Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I've owned a 996 C2 Cab 3.4 for 16 years. It had 50k miles when I got it and its now at 90k. It had a full Hartech inspection and top end rebuild 10 years ago and is generally in good nick all round. So now I want to address an annoying little niggle. When changing up through the gears during hard acceleration there is a jolt and a thump when releasing the clutch quickly. This can be avoided by feathering the clutch release. It doesnt occur under gentle acceleration or changing down and in all other respects, the car drives well. Its been there for ages and does not seem to be getting worse over time. I'm assuming its wear in the CV joints but this has never been picked up in any service or MOT. Can anyone shed any light on this? I have driven a similar age C4 which did not do it. Thanks!

POST 3Original post

I recently changed the engine mounts on my c4 which has improved the overall feel of the transmission. The clutch assembly could require cleaning and greased or replacing. Many aspects could contribute to feel of transmission over time.

POST 4 / ORIGINAL POSTEROriginal post

Good shouts. Thank you. I'll get those things checked at next service and feedback
