Default What is this thud

So I drove the car today (2000 WS6 m6) and it hasnt been driven in a few days. So when I go to pull out of my neighborhood as the clutch is engaging at the top of the pedal I hear and feel this thud. Its not bad but it is there. It only does it when I engage into 1st from a dead stop. I layed into first real hard and everything was fine. Now, if I really really baby the clutch it sometimes wont make the thud. I dont know what to make of this. It doesnt do it in any other gear. If anyone knows anything I would appreciate it. Its something every week with this car...

Does the shifter jump around at all?...Or do you just "hear" it.

it may be either tranny mount, but my car also if i just put it into 1st gear sometimes i hear like this slight knock! i think there may be a little play in my differnsials gearsm if your in 5th gear driving normal and you give it a little throttle and you see the shifter move up and down as your giving gas then its the tranny mount!

Ok ill try some gas in 5th gear. I dont think that it is anything serious because like I said I went WOT from 1st through 3rd and there were no issues whatsoever.

Agreed, I have personally had my BMR TQ arm bolt for the mount come out and since it opens on the top half the arm thuds against the underside of the body.

I agree. Its very possable its the t-arm mount. When I did the T56 conversion on my 94 B4C i forgot to put the top bolt in my t-arm mount and just closed the clam shell around the end of the t-arm.... All Ive got to say is WOW! Ive never seen my phone fly so high and into the rear hatch compartment when I dumped the clutch. It didnt "thud" it SLAMMED. Dented the floor and wedged the t-arm up above the trans. What a pain in the rear. Needless to say I never made that mistake again.

I have a Chrome moly end link on my Adj. TA and it thuds sometimes under conditions that seem similar to yours... Did you recently install a new TA?

Your transmission mount could be cracked too. I replaced on for a friend that was only halfway broken and it would still bump the floor. Check all your bolts and the t-arm mount. Good luck.
