Can a manual transmission make a knocking sound?
Noises – Ticking, Knocking, Clicking We will help you to make a list of noise that related to manual transmission problems. For instance, a clicking noise most probably means a broken tooth, while knocking sounds mean a damaged or broken gear. Last but not least, a ticking or bearing noise means a wrong gear.
What does automatic transmission make when in park, neutral?
Automatic Transmission has a noise (sounds like bad bearing) when in park, neutral and engine is running. The noise does varies with engine speed. When transmission is shifted to drive or reverse the noise goes completely away. Car runs fine except it has a little rough shift from 1 gear to 2nd gear during hard accelerations.
When does a bad gearbox make a clunking noise?
Commonly, the noise is loudest when letting out the clutch when taking off from a stop. Alternatively, if the rear transmission is bad in a rear-wheel-drive vehicle, the noise will occur when letting out the clutch in reverse as the tail shaft of the transmission rises up and slams back down. Broken mounts may also result in a clunking noise …
What causes an inefficient gearbox synchronizer to work?
Inefficient synchronizer performance can be caused by either a problem in the transmission, or by a separate clutch issue. While cone-like-synchronizers are simple and reliable, they rely on friction to function, and as such, the blocking rings degrade over time.
When does the noise of the transmission go away?
The noise does varies with engine speed. When transmission is shifted to drive or reverse the noise goes completely away. Car runs fine except it has a little rough shift from 1 gear to 2nd gear during hard accelerations. Any idea of what might be wrong?

What kind of noises do you hear when you shift gears?
Use some fast acceleration, allowing the transmission to firmly shift. Listen for any rumbling, growling or mechanical metal-to-to metal noise in each gear just after it shifts. Such noises indicate problems with the individual planetary gears, input shaft or interior transmission bearings.
Why does the torque converter make noise in neutral?
This puts the torque converter in operational mode. Since the torque converter pump, stator and turbine spin freely without engagement during neutral or park, the noise will not be present in those settings. Accelerate slowly in drive and listen to whether the torque converter noise will get quieter as the vehicle moves forward.
