Manual transmission problems can develop due to high mileage, abuse, or lack of proper maintenance. But they are rather rare. Most manual transmission issues originate not with the transmission itself, but from related components like the clutch assembly, linkage, or driveline: the components that transmit turning power from the transmission to the wheels. Also, as we discuss below, symptoms that seem to be coming from the transmission can come from unrelated parts of the car.
The key to diagnosing your manual transmission problem is to gather detailed information about the particular problem. For example, does the problem appear in only one of the gears, only at a certain speed, only when turning, only when downshifting, or after having serviced the clutch or another transmission component? Can you feel a vibration? Can you hear a clunking or grinding noise?
Then put the transmission in reverse. If it goes into reverse with no grinding you have no problem at all. If it does grind your clutch is dragging, possibly the pilot bearing has failed or the clutch disk is warped. There’s nothing unusual about the transmission grinding if you go directly into reverse from neutral.
Symptoms of a Bad Transmission
Here are some symptoms that can indicate a worn-out transmission, each one of which we discuss below.
- Odd sounds (whirring, squealing, bumping, or thumping)
- Grinding noise
- Transmission jumps out of gear (into neutral)
- Difficulty shifting gears
- Car stuck in one gear
- Car that can't get into gear
- Leaking transmission oil
This guide will get you started on identifying the source of these problems. You'll need to investigate further and remember that manual transmission configurations can change from one model to the next.
Remember that this guide only deals with symptoms coming from the manual transmission (or transaxle) itself. Some symptoms that may appear to originate in the transmission actually come from the clutch (or another system), and vice versa. To get a more accurate diagnosis, take a look at the Bad Clutch Symptoms guide as well.
1. Odd Noises That May Come From the Transmission
The most common cause of a noisy transmission is insufficient oil, causing the gears or internal assembly to hum or whir. If a noisy transmission does have enough oil, the lubricant may be contaminated with metal shavings or particles.
Insufficient or contaminated oil may cause the transmission to become noisy in some or all of the gears. But if you hear noises in a specific gear, that gear's teeth or synchronizer may be worn or damaged.
Sources inside the transmission that can cause noise:
Insufficient or contaminated oil may cause the transmission to become noisy in some or all of the gears. But if you hear noises in a specific gear, that gear's teeth or synchronizer may be worn or damaged.
Sources inside the transmission that can cause noise:
- A worn-out synchronizer
- The gears on the speedometer drive
- Misaligned transmission
- A worn or damaged input shaft bearing, if your transmission makes noises only in neutral (sometimes a bumping sound)
- Worn-out gears
- Output shaft pilot bearing problems
- Metal shavings in the oil
Sources outside the transmission that can cause noise:
Some noises that seem to come from the transmission are actually coming from an outside though possibly related source. For example, if you hear a thumping noise when you accelerate or decelerate, check first for these problems before you blame the transmission:
- A loose or damaged engine or transmission mount
- A worn or damaged drive axle inner CV joint
- Problems with the differential case
Noises that manifest when turning could point to a problem with the CV joint.Knocking noises when driving at low speeds could come from the differential case or the CV joint.
A Three-Step Test for Transmission Bearing Noises
That noise you keep hearing may come from a bearing. This three-step test is simple and can reveal problems with one or more transmission bearings.
A Three-Step Test for Transmission Bearing Noises
That noise you keep hearing may come from a bearing. This three-step test is simple and can reveal problems with one or more transmission bearings.
- Fire up the engine and set the transmission to neutral. If you can hear a noise in neutral, suspect a worn-out input shaft bearing. Watch the video at the bottom of this article to see how internal problems can affect input shaft operation.
- Now, with the engine running, depress the clutch pedal just enough to remove the free play, to the point where you feel you need to apply force to the pedal to push it down further. You may need to push the pedal a little more. If you hear a squealing noise, you may have a worn out release bearing.
- Fully depress the clutch pedal to release the clutch. If you hear a whirring sound then, you probably are dealing with a bad pilot bearing.
2. The Transmission Makes a Grinding Noise
Problems with the transmission can also be revealed through a grinding noise.
A grinding noise may come from clashing gears. The clashing may happen because of linkage problems like wear or need of adjustment.
Other potential sources could be a worn or damaged synchronizer, shift fork, or rail and bearing shafts.
If you can hear the gears clashing only when downshifting, the problem may come from the synchronizer (too much play at the output shaft end).
However, a grinding noise may also come from a dragging clutch.

3. The Transmission Jumps Into Neutral
This seems to be a common problem on worn-out transmissions. You shift into gear, and the transmission jumps out of gear.
Once again, there could be other several causes for this problem, besides a worn-out transmission:
- A common problem is a worn out, stretched, or maladjusted shift linkage. A stretched linkage can be caused by a damaged engine or transmission mount. An external linkage can wear out or become loose and maladjusted, causing the transmission to jump out of gear. Look for rust and binding. You can try to adjust the linkage. But in most cases, you'll have to rebuild or replace that part of the assembly.
- You may be dealing with a weak or broken spring in the shift rail. In an internal shift linkage, the spring is part of the spring-loaded ball that locks the transmission into gear. If the ball slips out of the notch, the transmission will jump out of gear.
- Also, you may be dealing with a worn-out pilot bearing (the gap causes the input shaft to vibrate, which causes the shift forks or synchronizers to move).
- You may have problems with a worn synchronizer or shift fork assembly or other internal components.
Other potential causes to keep in mind:
- Loose or misaligned transmission (possibly after service)
- Misaligned clutch housing
- Loose shifter cover
- Worn-out gear teeth
Note: When the transmission only jumps out of a high gear, check the clutch housing bolts for tightness, or the transmission for misalignment.
4. It's Hard to Shift Gears
This problem happens when you find it hard to move the shift lever from one gear to another. Usually, this points to a problem with a loose linkage, worn shift cables or worn bearings.
Check the linkage. You may need to raise the vehicle and safely support it on jack stands or remove a component in order to make the inspection, depending on your vehicle model. You may need to remove a shift lever boot.
Get the help of an assistant to operate the linkage while you inspect the linkage, if necessary. Look for problems like binding, poor lubrication, misaligned components.
To remove components for inspection, consult your vehicle repair manual. Haynes is a good aftermarket manual: get the manual for your exact model.

- Worn or loose internal components (shift fork, levers, shafts)
- Low oil level (or the wrong type of oil)
- Misaligned transmission
- Synchronizer problems
5. The Transmission Is Stuck in Gear
You may find that you can't get the transmission out of gear. This symptom may indicate:
- Low oil level or the wrong type of oil
- Problems with the linkage or shifter assembly. Look for maladjustment, or wear or damage to rods, bushings, or shifter arms.
- Internal components: shift rail, detents, forks or a stuck synchronizer sleeve
- Worn-out or broken drive gear teeth
- A stuck shift rail
- Misaligned transmission
6. The Transmission Won't Get Into Gear
When you have trouble getting the transmission into gear, inspect the shift linkage for adjustment, looseness or damage.
However, remember that failure to get into gear can also be caused by the clutch, if the clutch isn't fully releasing or has other problems. The clutch might need adjustment. Check my article on bad clutches. Also, consult your vehicle repair manual.

7. Leak From the Transmission
Manual transmission leaks can be caused by:
- bad or worn-out seals or gaskets,
- a damaged case or component,
- or even loose bolts.
To verify that a leak exists, first, check the transmission case and oil level. If it leaks after you just replaced the oil, you may have put too much. Consult your vehicle repair manual.
Locate the source of the leak. Inspect the transmission oil seal and the O-ring in the vehicle speed sensor.
Consult your vehicle repair manual for the proper procedure to replace seals, bearings, or gaskets. Some of these repairs don't require much work, and you may be able to do the job in your own garage with a few common tools.

Knowing about common manual transmission problems can help you diagnose your problems sooner, and possibly save money. This guide helps you identify and explore those common and not-so-common areas. Still, manual transmissions vary between models, so once you have an idea of the possible problem with your transmission, consult your model's vehicle repair manual to troubleshoot that particular issue. You may be able, in some cases, to do the repair yourself.

- My 69' VW Beetle makes a grinding noise when trying to shift into 2nd gear. If I shift into 1st with the clutch pressed and then try 2nd again, it will go into it fine. Do you have any ideas as to what might the problem be?Check the clutch linkage, there could be some binding. Another possibility is low oil or synchro worn.1
- My 98 Neon grinds when shifting into 1st and 2nd. There’s not any grinding sound. It just feels not smooth when shifting. Is this the CV joint? Or is it a transmission problem?Usually CV joints will feel rough, produce a humming or growling noise when dry, and usually, the bearings will be worn. But make sure your gearbox has enough oil.
- So when I let off of the gas of my car (but still in gear) at highway speeds (50 mph plus) there's a thumping and bumping noise. I can feel it very slightly! My question is, what would cause this? I have no other issues with shifting. I just noticed it happening today.Usually, this type of noise comes from a worn universal joint; but other related issues that may cause noises during deceleration or even acceleration - axle bearings, or a worn transmission extension housing bushing.4
- I have a 06 Scion. In first and second gear only you can literally feel the entire gear shift pull forward when accelerating. In second gear, it pulls so hard it drops to gear shift back into neutral. If I try to hold the gear shift in second, it grinds. Third, fourth and fifth are all fine. Do I need a new transmission?There could be a number of things. Gearshift, shift fork or rail problems, clutch shaft or synchronizer assembly damage.2
- I have a 97 LS Integra with 134000 miles on it. It makes a grinding noise at roughly 3000-3600rpm, 4000-4300rpm, and 5000-6500rpm in all gears, as well as in neutral. Any ideas of what it can be?There are several reasons for this: first make sure there's enough lubricant; worn bearings, gears or synchronizer can also cause this.1

- I have a 1998 dodge Dakota 3.9l with a 5 speed transmission AX-15 and at 35 mph it jumps out of gear
- 96 maxima makes noise when clutch pedal is out and in 123rd gear when you let off of gas pedal sounds like a 4/11 in old chevy truck
- I have a BMW 1 series 2009 6 speed manual. I can shift into 2nd gear but when I release the clutch I get lots of grinding, the gear stick vibrates and ultimately I can’t drive in the 2nd gear. It’s only this gear I’m having issues with, any ideas?
- When driving my manual 2000 VW Beetle... just had clutch changed...All of a sudden the car seems to be over revving when going from second to third gear... like it has power bit the car is acting like it does...any idea?
- I have noticed recently a whining noise only in 5th gear of my 2000 Toyota Camry 4 cylinder. I am thinking that I need to change the gear oil and I haven't done so but can this be the problem?
- I have a 1985 F250 6.9 IDI 4 speed with a gear splitter, My truck makes a whirring type noise when accelerating in 2nd and 3rd gear. The noise only happens when i'm accelerating. If i ease off the accelerator to the point where I'm not pushing the truck, the noise stops. When i shift past 3rd into 4th, no noise. I checked gearbox oil, gear splitter oil and diff fluid - all levels okay. Any ideas would be much appreciated.
- Hi Dan,I was wondering if you could help me. I have a Ford Transit 1987. It pops out of 3rd gear into neutral whilst making a grinding noise and it is becoming increasingly difficult to get into 2nd gear...do you know what might cause these problems? Thank you
- 2013 vw beetle will only go in rev 1st & 5th can anyone out there help me
- Howdy.. I’ve got a question regarding the manual transmission in my husbands 87 Jeep Cherokee YJ. I’ve read several possibilities as to why it’s popping out of gear and or getting stuck in gear. I was hoping to narrow the field of possibilities down a bit. Could you tell me the most common causes/reasonings for the Jeep to jump out of and become stuck in the 3rd & 4th Gear’s ?!I’m hoping the issue at hand is maybe a little more pocket friendly if you know what I mean ?! This of course starts happening right as I was going to surprise him with a 6” lift and 33” tires.Any advice suggestions or direction you’d be willing to share with me would be much appreciated ! Thank you
- I have a 93 ford ranger 2.3l 5 speed I bought about 3 months ago and it’s becoming increasingly harder to shift. It seems to be intermittent but when it is bad it’s crunchy to shift and almost impossible to get into gear. I was told it was low or bad fluid
- Thank you. One thing I have to tell you is that when idling and neutral position if I push lever to 1st to 5th gear one by one (without pushing pedal, so gear will not engage) the sound become lower.
- My Land cruiser 105 manual transmission has whiring sound from gearbox when idling in neutral position and the sound disappears when pushing clutch pedal. Everything works well but the sound. I changed input, output, counter shaft, flywheel bearings and clutch & cover discs, but the sound doesn’t disappears. All gears looks good condition. In cold start its sounds very low and when the oil is warmed up it’s sounds louder. As I am well experienced mechanic I know that it’s not common problem, please advise me. Thank you.
- I have a 2004 dodge dakota my transmission was ran 6 months without fluid do to a idiot Tech when first got it it was fine about 6 months later is whines in all but 4 gear what could be the problem also about 2 months ago my throw out bearing exploded so we replaced it and the slave cylinder and now about middle of my peddle my clutch sqeeks
- I have a 03 ford ranger. I have a hard time shifting gears and there are times i cant even shift in gear.
- why the 3rd gear of Toyota land cruiser out when driving after few minute drived
- I floored my 96 Integra gsr today and there was a loud band sound when shifting from 1st to 2nd. After, I could not get out of 2nd gear but when I came to a complete stop, the car drove perfectly fine again. What could be the problem?
- My Triton has abnormal sound when in 5th gear .. at 2000RPM and above..when I depressed the gas pedal no round...No sound for gear 1, 2 , 3 and 4 even if at 2000RPM and up..What could be my issue? Broken gear (5th)... if yes, if you are to repair this, the entire tranny will be pulled -out??Thanks.
- I have a 2004 Dodge Dakota 5 speed -shifts fine but starting from a stop in first gear, there is a clunk as i release the clutch it feels like it is engaging the gear.
- I have a 1996 dodge dakota that whirls and is sometimes hard to shift but not all the time, it pops out of gear sometimes as well
- I put my truck into 4wd and as soon as I started up a hill I heard a loud clanking sound it did it twice.
- Bought son 2013 dodge dart w 6speed Manuel, C635 im told, installed new slave, whent to bleed and realized no fluid getting to slave, just very small sauirts when you push pedal w hand, master is located near bottom of wall, how do i get fluid through it to the slave?? Then i realized the slave dont even have a bledder screw, jist a 1/4' nipple w rubber tip on it, alot money and time invested, dealers wont help and no parts store either, need halp bad please. College jyst started back, he really needs it. God bless.
- @ HaroldIt sounds like you are referring to an automatic tranny (mention of putting the tranny in 'park')This article is about manual transmissions, however your problem sounds like either a bad boost valve, broken sun shell, or band
- My car wont change into gear at high rpm. I move the shifter into position but it wont engage the gear and just stays in nuetral. When i drop back down to say below 4500rpm i have no problem other than second which takes a little while to come right. I have no problems while the car is in any gear only while trying to shift. Car is a 1999 toyota caldina gt-t 4wd turbo.
- I sent a question at the top where it says ask but didn't seem to go through. A Chevy 4×4 Silverado has has two rebuilt trans in it within a month. It has all gears working yet no reverse and no noise. Any suggestions. I also noticed shift linkage not right as it's only going as far as second to park. Any idea's. Something is telling me it's asimple fix. Thanks
- we have a honda crv 2003 and the pilot bearing went the mechanic said we need to replace the clutch kit and a gearbox is this correct.
- Good day DanIf you have the time I would like to see what your opinion is on my current situation. I have a 2011 Camaro RS v6 manual transmission I purchased the vehicle almost a year ago and at the time I noticed that it was having some issues going into 3rd gear. I informed the dealer they looked at and said it was nothing!!!!!! Now it's in the shop and it will not even go in 3rd gear and slipping out of gear as well. At the time of purchase I did get the extended warranty that covers everything (I thought). They sent out someone to look at the failed part but what do you know he decided it to be because of the way I drive the car. I need to know what to look for when there is a failure part or abused driving cause I am having them send another adjuster and I want to be there. Thanks for your time.
- Hi I'm working for a rather small towing yard and we do most repairs here at the shop. Our main mechanic just quit and they are now asking me to attempt to fix our service truck. But I am having trouble finding the issue. I have replaced the clutch pressure plate and slave cylinder but it still will not shifting when running. With the clutch pressed in trying to shift into any gear the truck starts creeping in the direction the gear carries it. Any help would be greatly appreciated
- Yeah I had a vibration coming from the from the front of my SM465. Turns out the needle bearings on pilot were gone. And it mushroomed the input shaft. I was happy just to have a spare SM465 to replace it. Now I have time to rebuild the old one and replace that shaft.So new clutch, new slave cylinder (I like the old rod and spring version better though) and replaced trans. Had it back on the road by night fall and readly to pull heavy hay wagons in the morning.

In second gear, it pulls so hard it drops to gear shift back into neutral. If I try to hold the gear shift in second, it grinds. Third, fourth and fifth are all fine. Do I need a new transmission?There could be a number of things. Gearshift, shift fork or rail problems, clutch shaft or synchronizer assembly damage.2
- I have a 97 LS Integra with 134000 miles on it. It makes a grinding noise at roughly 3000-3600rpm, 4000-4300rpm, and 5000-6500rpm in all gears, as well as in neutral. Any ideas of what it can be?There are several reasons for this: first make sure there's enough lubricant; worn bearings, gears or synchronizer can also cause this.1

- I have a 1998 dodge Dakota 3.9l with a 5 speed transmission AX-15 and at 35 mph it jumps out of gear
- 96 maxima makes noise when clutch pedal is out and in 123rd gear when you let off of gas pedal sounds like a 4/11 in old chevy truck
- I have a BMW 1 series 2009 6 speed manual. I can shift into 2nd gear but when I release the clutch I get lots of grinding, the gear stick vibrates and ultimately I can’t drive in the 2nd gear. It’s only this gear I’m having issues with, any ideas?
- When driving my manual 2000 VW Beetle... just had clutch changed...All of a sudden the car seems to be over revving when going from second to third gear... like it has power bit the car is acting like it does...any idea?
- I have noticed recently a whining noise only in 5th gear of my 2000 Toyota Camry 4 cylinder. I am thinking that I need to change the gear oil and I haven't done so but can this be the problem?
- I have a 1985 F250 6.9 IDI 4 speed with a gear splitter, My truck makes a whirring type noise when accelerating in 2nd and 3rd gear. The noise only happens when i'm accelerating. If i ease off the accelerator to the point where I'm not pushing the truck, the noise stops. When i shift past 3rd into 4th, no noise. I checked gearbox oil, gear splitter oil and diff fluid - all levels okay. Any ideas would be much appreciated.
- Hi Dan,I was wondering if you could help me. I have a Ford Transit 1987. It pops out of 3rd gear into neutral whilst making a grinding noise and it is becoming increasingly difficult to get into 2nd gear...do you know what might cause these problems? Thank you
- 2013 vw beetle will only go in rev 1st & 5th can anyone out there help me
- Howdy.. I’ve got a question regarding the manual transmission in my husbands 87 Jeep Cherokee YJ. I’ve read several possibilities as to why it’s popping out of gear and or getting stuck in gear. I was hoping to narrow the field of possibilities down a bit. Could you tell me the most common causes/reasonings for the Jeep to jump out of and become stuck in the 3rd & 4th Gear’s ?!I’m hoping the issue at hand is maybe a little more pocket friendly if you know what I mean ?! This of course starts happening right as I was going to surprise him with a 6” lift and 33” tires.Any advice suggestions or direction you’d be willing to share with me would be much appreciated ! Thank you
- I have a 93 ford ranger 2.3l 5 speed I bought about 3 months ago and it’s becoming increasingly harder to shift. It seems to be intermittent but when it is bad it’s crunchy to shift and almost impossible to get into gear. I was told it was low or bad fluid
- Thank you. One thing I have to tell you is that when idling and neutral position if I push lever to 1st to 5th gear one by one (without pushing pedal, so gear will not engage) the sound become lower.
- My Land cruiser 105 manual transmission has whiring sound from gearbox when idling in neutral position and the sound disappears when pushing clutch pedal. Everything works well but the sound. I changed input, output, counter shaft, flywheel bearings and clutch & cover discs, but the sound doesn’t disappears. All gears looks good condition. In cold start its sounds very low and when the oil is warmed up it’s sounds louder. As I am well experienced mechanic I know that it’s not common problem, please advise me. Thank you.
- I have a 2004 dodge dakota my transmission was ran 6 months without fluid do to a idiot Tech when first got it it was fine about 6 months later is whines in all but 4 gear what could be the problem also about 2 months ago my throw out bearing exploded so we replaced it and the slave cylinder and now about middle of my peddle my clutch sqeeks
- I have a 03 ford ranger. I have a hard time shifting gears and there are times i cant even shift in gear.
- why the 3rd gear of Toyota land cruiser out when driving after few minute drived
- I floored my 96 Integra gsr today and there was a loud band sound when shifting from 1st to 2nd. After, I could not get out of 2nd gear but when I came to a complete stop, the car drove perfectly fine again. What could be the problem?
- My Triton has abnormal sound when in 5th gear .. at 2000RPM and above..when I depressed the gas pedal no round...No sound for gear 1, 2 , 3 and 4 even if at 2000RPM and up..What could be my issue? Broken gear (5th)... if yes, if you are to repair this, the entire tranny will be pulled -out??Thanks.
- I have a 2004 Dodge Dakota 5 speed -shifts fine but starting from a stop in first gear, there is a clunk as i release the clutch it feels like it is engaging the gear.
- I have a 1996 dodge dakota that whirls and is sometimes hard to shift but not all the time, it pops out of gear sometimes as well
- I put my truck into 4wd and as soon as I started up a hill I heard a loud clanking sound it did it twice.
- Bought son 2013 dodge dart w 6speed Manuel, C635 im told, installed new slave, whent to bleed and realized no fluid getting to slave, just very small sauirts when you push pedal w hand, master is located near bottom of wall, how do i get fluid through it to the slave?? Then i realized the slave dont even have a bledder screw, jist a 1/4' nipple w rubber tip on it, alot money and time invested, dealers wont help and no parts store either, need halp bad please. College jyst started back, he really needs it. God bless.
- @ HaroldIt sounds like you are referring to an automatic tranny (mention of putting the tranny in 'park')This article is about manual transmissions, however your problem sounds like either a bad boost valve, broken sun shell, or band
- My car wont change into gear at high rpm. I move the shifter into position but it wont engage the gear and just stays in nuetral. When i drop back down to say below 4500rpm i have no problem other than second which takes a little while to come right. I have no problems while the car is in any gear only while trying to shift. Car is a 1999 toyota caldina gt-t 4wd turbo.
- I sent a question at the top where it says ask but didn't seem to go through. A Chevy 4×4 Silverado has has two rebuilt trans in it within a month. It has all gears working yet no reverse and no noise. Any suggestions. I also noticed shift linkage not right as it's only going as far as second to park. Any idea's. Something is telling me it's asimple fix. Thanks
- we have a honda crv 2003 and the pilot bearing went the mechanic said we need to replace the clutch kit and a gearbox is this correct.
- Good day DanIf you have the time I would like to see what your opinion is on my current situation. I have a 2011 Camaro RS v6 manual transmission I purchased the vehicle almost a year ago and at the time I noticed that it was having some issues going into 3rd gear. I informed the dealer they looked at and said it was nothing!!!!!! Now it's in the shop and it will not even go in 3rd gear and slipping out of gear as well. At the time of purchase I did get the extended warranty that covers everything (I thought). They sent out someone to look at the failed part but what do you know he decided it to be because of the way I drive the car. I need to know what to look for when there is a failure part or abused driving cause I am having them send another adjuster and I want to be there. Thanks for your time.
- Hi I'm working for a rather small towing yard and we do most repairs here at the shop. Our main mechanic just quit and they are now asking me to attempt to fix our service truck. But I am having trouble finding the issue. I have replaced the clutch pressure plate and slave cylinder but it still will not shifting when running. With the clutch pressed in trying to shift into any gear the truck starts creeping in the direction the gear carries it. Any help would be greatly appreciated
- Yeah I had a vibration coming from the from the front of my SM465. Turns out the needle bearings on pilot were gone. And it mushroomed the input shaft. I was happy just to have a spare SM465 to replace it. Now I have time to rebuild the old one and replace that shaft.So new clutch, new slave cylinder (I like the old rod and spring version better though) and replaced trans. Had it back on the road by night fall and readly to pull heavy hay wagons in the morning.
