In manual transmissions, the reverse gears use a different type of gear teeth than forward gears. When your transmission is under load (clutch engaged, in gear), you won't necessarily hear it. Consult your repair manual for the location of these components. Hey guys! The most common cause of a loud transmission is low oil, causing the gears or internal assembly to hum or whir. The Transmission Makes a Grinding Noise. This difference is governed by the bending of the gear teeth from the torque placed upon them, defects and the dynamic behavior of the gearbox at the rotational speeds considered. See our, How to use Equivalent Damage Methods for…. If you are sure the noise is coming from your gear box and happens even in neutral, then the output shaft bearing in your transmission may be starting to go bad.

Similarly for any of the modes of the system that generate unwanted noise, structural modifications of the casing design can be incorporated. for instance, does the problem appear in only one of the gears, solely at a precise speed, only when turning, only when downshifting, or after having serviced the clutch or another transmission component? If a manual transmission makes noises just when the clutch pedal is all the way up or engaged and a grinding or rattling noise is heard, the throw-out bearing for the clutch is bad. Problems with the linkage or shifter assembly. Since the gear train has not been engaged in drive, it rules out all the other components. Reverse gears are … So sounds that occur while the car is stationary and in gear are most likely associated with the clutch.
