hi I own a 1997 camaro z28 and my consal vibrats when i drive at high speeds it only started doing it after i rebuilt my transmision. can anyone help me out if they no what it is ??

its not the trany mounts cause they replaced those already twice. I brought the car back to the shop and they could not find the problem can anyone help me plz..

 

what kind of trans mount did they put in. the poly mounts will transfer vibrations bad.

 

Even worse effect with poly motor mounts also.

 

im not to sure what kind of mounts they are he never told me I put a shift kit in my automatic transmission and it staped my stock tranny mounts twice. but even when i had my stock mount since it came out of the shop with a rebult tranny it seemed a lil diffrent and started vibrating the consal

its pissing me off and i need to find how to fix it !!!

 

You could have a u joint going maybe, but I would think that would show up at slower speeds. What you're describing is exactly what mine does with the poly trans/motor mounts. It's really not that noticable any more though. I had to put some tubing around the parking brake spring to keep that from rattling. Maybe driveshaft out of tune, I wish I could help for sure.

 

get under there and have a look, if its solid it poly, many are red in color. if theres a hole going through it that lets it flex then its stock. u may be able use something like this to take some of the pressure off the trans.
