Judder when downshifting into 2nd

Hi folks,

When downshifting into 2nd gear without rev-matching, I get some judder when I release the clutch. Doesn't happen in any other gear and there are no obvious other symptoms.

Any suggestions?

Thanks.

Karl.
 
Yes it seems to happen on a lot of 944S2,s....
I had this EVEN after a new clutch + flywheel re-surfaced....[8|][8|]
 
It does seem to be an S2 trait, it happens with mine in normal speed change downs, but only as you say 3rd to 2nd. If you speed the change up it does not happen, or at least if far less noticable. Another S2 that does it is in for a new clutch at the moment, it will be interesting to see if it still does it.

It may be the flywheel face , but I have a feeling it may have something to do with older clutches and weaker clutch springs. (I know that goes againts B Dave having a new clutch)

 
My Lux (and my previous one IIRC) has done this on both the first and new gearbox / clutch. Never progressed however and as you say was only ever going down into 2nd.
 
Ever had your diff carrier bearings checked?

Rubber or spring centre clutch?

Engine mount condition?

Hi Jon,

Never had the diff carrier bearings checked.

I believe its on its original (rubber center?) clutch with 135K miles. And if I do a hard 1st gear launch the clutch will slip a bit (I've 255 wide Avon tyres on a 17x9" rims in the rear), so in general I think the clutch is beginning to show signs of wearing out. But I didn't know if that's the cause of the judder and feedback from folks to date seems to imply its a coincidence (unless rubber bits are the cause).

As regards the engine mounts, not in great condition.

Thanks for the pointers. Plenty to keep me busy...

Karl.
