I dont know what trans you have, auto or stick. I dont know how the 4+3 mounts... but if it is like my 90 6 speed, and I am thinking it is... I would say you dont have a trans mount to replace.

whats the problem?
I am not sure what you are looking for.

There is no transmisson mount on C4's auto or manual. Are you talking about removing the C-beam??

I am having a semi loud "clunk" when I put auto in drive, or when the tranny down shifts. Reverse has no problems-very smooth. Just got new tires on it, and it still tends to vibrate pretty good around 70 mph. Maybe a joint of some sort? I am used to old school cars-this car is a trip.

My bet is a universal joint as well.

Does it do it worse as you accelerate to 70, then settle down as you let off the throttle?

On the plus side of not having a trans mount, you get a C brace. which makes removing the drive shaft a PITA.
