Manual transmission makes noises

The truck has gone close to 200,000 miles. A month ago, the manual transmission started making noise in third and fifth gear. It occurs when the drivetrain is loaded or gas pedal depressed. When there is no load, there is no noise at all, whether in gear or during coasting. I had all the fluids checked and they look fine and are at good levels. There is also noise that has been occurring for a couple of years now. It's noticeable when my foot is off the clutch and I put it in drive or neutral. If I then press the clutch, there is no noise at all. What could be causing this?
Experienced mechanics share their insights in answering this question :
Hello. It sounds like you have a gear, bearing, bushing, or other rotating component issue caused by wear. At that mileage, really the thing to do is just simply rebuild the transmission which is not particularly difficult since it is manual type. There are probably multiple parts which are worn and all should be simply addressed at one time. If you need to have this checked out, a certified technician from YourMechanic can come to your car’s location to diagnose the noise and let you know what needs repair.

Bearing, gear and shaft wear are the most common causes of noise. As gear tooth faces and bearing races wear, they develop groves and small pits. While these are only small at first, they will gradually become larger, and as they grow, these imperfections will cause even more noise to occur.
If you hear a humming noise in all gears, you may be dealing with a worn or damaged shaft or bearing. If you hear a growling noise specifically while moving, it is usually caused by a bad input shaft bearing.
When you hear a grinding sound, this happens because that collar that is colliding with the end of the gear is spinning at a slower or faster rate compared to the shaft in your transmission. To limit this grinding sound, a synchronizer ring is used to match these speeds effectively.
This noise is caused by the excess air in your transmission line. Commonly, drivers will notice this gurgling noise when their transmission slips while shifting gears. If you hear a gurgling noise, particularly while shifting gears, it may mean that your fluid levels are low enough to cause damage to your transmission.
Beware a shake, jerk or grind

Automatic gearbox telltale signs include hesitation, slipping, or “trembling” during gear changes. Manuals are more likely to grind. Jerking and clunking noises are more likely to be caused by failing engine and transmission mounts.

Strange Noises

If the sound resembles humming, buzzing, or clunking, you may be experiencing transmission failure. Bad automatic transmissions may emit humming, buzzing, or whining noises while manual transmissions have harsher “clunking” sounds.

My Gears Are Clunking, Clicking Or Rattling

These noises usually mean that your gearbox or engine is on it`s way to failing, which can be catastrophic if you are driving at the time. For this reason, you should try and have the car collected rather than driving it to the garage.

While a slightly damaged release bearing usually causes a whining noise, a severely damaged release bearing often produces loud, grinding noises when it is placed under pressure.
You may feel or hear an awkward clunking noise when you are accelerating or decelerating. Again, it may be low transmission fluid or it could also be damaged gears. The gears might be slipping between shifts and this leads to those noticeable clunks.
Gearbox bearing failure symptoms cause shaking, jerking or grinding and will affect the steering wheel. Automatic gearbox problems often cause problems like hesitation, slipping, or trembling during gear changes. Manual cars usually make a grinding sound if it has a gearbox fault.

The short answer to this question is no, you should not drive with a bad transmission. Sometimes, life happens, and you have to keep driving your vehicle even though you know that it needs to be serviced.
If you hear a high-pitched squeaking as you press the pedal then you know that you have a problem with your clutch. This sort of noise is usually associated with problems with the clutch release or throw-out bearings.

There is automatic transmission fluid in a manual transmission. Is it okay to leave or do I need manual transmission fluid?
ANSWER : This would depend on what the manufacturer recommends. Many manual transmissions do take automatic transmission fluid. If your transmission has ATF in it, it is very likely that it is supposed to have that in there. If not, it is likely that the transmission would not function properly with the wrong fluid. Many manual transmissions will also take engine oil as a lubricant. The best way to know for sure is to check your owner’s manual or call your local General Motors dealership to inquire.

car making womp womp noise and pop
ANSWER : A common cause of a noise like that is tire belt (internal) separation, flat spot(s) on tire or other tire defects. If the tires end up being excluded during a diagnostic, the CV axles, wheel bearings, and unfortunately the transmission and clutch have to be considered. The noise on turning is suggestive of a possibly defective outer CV joint but very loose tie rods ends and ball joints can sometimes be implicated. Also, it is possible to have a bad strut bearing, in the strut mount. Keep in mind, a "combination" of faults might be in play here. Your best bet is to request a front end inspection/diagnostic during which the responding certified mechanic will get this resolved for you insofar as identifying the root cause(s) and estimating the repair for you.

Car makes grinding noise – 1996 Chevrolet Corsica
ANSWER : Hey there, thanks for writing in. I would have a professional mechanic check out the constant velocity joints on your vehicle. One or more of them may be worn enough to cause the noises you describe. S/he can diagnose and replace any failed CV joints.

when i turn it make little noise. when press on brake and put on reverse it’s makes weird noise and shakes. thank you
ANSWER : It sounds like you may be dealing with a few issues. I would start by asking if there is a check engine light on? If there is, then getting the engine control module scanned for faults would be the first step to diagnosing the low power issue. As far as the noise over bumps and when turning, there could be a damaged CV joint or axle shaft, or there could be a loose suspension or steering component. Weak motor mounts could cause a weird noise and shake when going into reverse with your foot on the brake, so it’s possible those have failed as well. I would suggest having a qualified mechanic, such as one from YourMechanic, diagnose the noise over bumps and the noise when put in reverse.

Chattering noises coming from transmission
ANSWER : Hello. From the symptoms you’ve described it would appear to me that there may be an issue with the clutch disc or perhaps flywheel.

If the contact surfaces of either are excessively worn it may cause intermittent chatter, as you are experiencing. If the clutch is still the original one than it may need to be replaced.

If you’d like a second opinion on this or would like to get this fixed, consider getting some help from a qualified mechanic who can diagnose the noise your car is making. Once this assessment is made an accurate repair can then performed.

Whining noise from transmission and difficulty in shifting
ANSWER : Hello. From what you describe it would appear that your vehicle has developed some sort of issue with the transmission, perhaps related to the hydraulic system, or with the transmission gears. If there is an issue with the vehicle’s hydraulic clutch system it may cause problems such as grinding or popping when putting the transmission into gear. The components to look at there would be the clutch master and slave cylinders. If the clutch appears to be engaging and disengaging properly then it may be possible that the issue is with the transmission, perhaps in the form of a bad throw out bearing, or worn transmission gears. Both of these could also cause a whining noise as well as difficulty changing gears if a problem occurs. I would also check the fluid levels for both the transmission and hydraulic clutch systems, as that could also cause similar symptoms. If you are unsure I would recommend having a professional technician, such as one from YourMechanic, come to your location to diagnose what may be causing your transmission issues.

My car makes a really annoying noise and sometimes dies right after
ANSWER : Hi there. From the description you have provided your vehicle’s moaning noise and intermittent stalling problem could be any number of things. It could be a failed alternator diode making the moaning noise and affecting the idle.

A failed alternator diode(s) allows voltage to flow both directions or no flow at all resulting in noise heard and erratic electrical operation. It could be a faulty idle air control valve. The idle air control valve can make noise and would account for the erratic idle and sporadic dying. It could be an accessory component, such as an A/C compressor, serpentine belt tensioner, or idler pulley, power steering pump making noise and placing undo load on the engine at idle. If you would like to have this done, a certified professional from YourMechanic can come to your car’s location to diagnose the noise and stalling issue.
