when backing up and abrublty push in the clutch (disengage), I get this hellascious clunky clunk noise, did it since day one, does not do it if you press the clutch in slowly when backing up.

I can get the same kind of noises on my sportscars and on my S10 truck. I think it's just a function of the way your unloading the clutch/tranny in reverse.





Cure???

A lot of times vehicles with softer engine/tranny mounts will allow some excess movement, and often times you'll hear about it. You might want to have the dealer check into it, but it might only be a "normal" amount of driveline movement.

I've got the same thing. The drive shaft is pretty big and the dampener/balancer whatever next to the pinion adds to the inertia in the system.
