when i step on the gas all the way, i hear a clunk clunk from the rear of the car, like it's coming from the trunk but it's from under the car. any ideas guys?

My Camaro does the same thing, what the hell is that?

i would guess its a bad tranny mount

cheap and easy to fix

thanx bro, u are givin me alot of help tonight:hail: :hail:

It's probably the tranny mount very easy fix, or it could be U-joints but iam not to sure on that.

no prob man, i do what i can

dont go out any buy the tranny mounts just yet like my stupid a$$ did look under, some bolts just might be loose.

Changed the mount yesterday and I fixed the problem perfectly. Shifts great and no more clunck.

congrats! such a small part, however, stops the clunk that sounds like your car is falling apart!!

i have the same problem, i get a multiple of clunks when my tranny downshifts, i have a new Prothane tranny mount, so unless those things only last a few hundred miles i believe it is my u joints which i plan on changing within the next 2 weeks. Ill let you guys know if it fixes my problem.

how easy is this to do, i mean, if it's the mount, am i gonna have to un mount the tranny to change it? will i have to jack up the entire vehicle on a lift or will jacking in up with a floor jack do the trick?

to change the mount, i jacked up the front of the car, and put it on jackstands. Then i unbolted the mount and jacked up the tranny by the tranny pan (use a block of wood or something to keep from damaging the pan). THen just change the mount. Its that simple.
