Clutch/Transmission Noise

xlid007 · 12-20-2012, 01:55 PM

I get this weird clunk sound when I release the clutch and go into a gear. Does't matter how slow or fast I release it. It's worse when I go at slow speed/RPM. Sometimes if I shift around 3-4k it's very faint. The clunk can be heard and felt inside the car. It feels like it's coming from the rear of the car. The car was put on a lift and no mounts were torn nontheless. It happens 100% of the time if I'm in stop and go traffic and I release the clutch at around 1-2k RPM. Also, it occurs no matter if I'm upshifting or downshifting.

I believe I am experiencing the same issue. When I disengage the clutch at low rps, car rattles. It is very annoying. Not all the time though. And I have no idea if it has to do with engine, transmission, or clutch.

my issue described above is finally fixed. Had my valves walnut blasted this last weekend and the rattle/clunk when shifting is completely gone.. after months of putting up with it.. car feels now like the first day it was driven

How does cleaning your intake valves fix clunking in your transmission?

To the OP:

Have you thought about changing your clutch fluid and bleeding it? That's what I would do first.

I'd then look into a transmission fluid change if you have offer 50,000 miles.

I don't know, just sharing my experience.. perhaps the clunking was caused by the engine?

Unlikely. Clunks are usually caused by bushings.

perhaps clunk is a very generic term.. this "clunk" was not the suspension noise type of clunk
