Big bang when punched (automatic)

Well i just test drove a 1996 automatic z28 and there is a BIG bang when you punch it from a 10mph roll, the tranny shifts great and if not being punched, theres no bang. It sounds like its coming from the rear end, but the owner thinks its the tranny? Any ideas??????

could be tranny backlash or maybe a little too much play somewhere in your drivetrain...i have a 97 auto that i think does the same as what your talkin about.

I say it is the tranny mount, I've had that problem

what is tranny backlash?

lol...its the transmission mount. 25 bucks and its gone

Tranny mount. Get the Poly mount and be done with it.

Get an LS1 tranny mount. Poly vibrates too much :(

definately the trans mount ive been through many lol. i duno about the poly mounts.. heard lots on their vibration when i posted about it awhile back, but im in the process of testing an LS1 style mount now like it so far :) if it breaks before next year im getting a poly mount lol

man that be great, sence the car doesnt do it when normal driving easy, the seller failed to mention it hopes that it wouldnt be punched in a residential area. So he tried to screw me, he thinks its the transmission itself, but hes willing to deduct for the bang now so i can get it super cheap (i could replace the tranny and would still be getting a great deal), and really he deserves it i think for trying to hide it! Anyways so can anyone think, or has had anything happen that it could be the rear end or the tranny????

poly mounts suck, they are string, but vibrate terrible. At least on my car. I took it out and put a factory rubber mount back in. Probably won't last long . LOL.

i have poly and do not notice the shaking... i broke 3 rubber and put poly on now its fixed for good. call a tranny shop and ask how much it cost to rebuild for that camaro. then tell the seller what he said. this will help get the price down. then tell him the car is gonna be down for a week so then you won't be able to drive it. then say with the tranny broke its apparent that you coule have abused the car so your thinking about not even buying it.

this is gonna get you the car cheap........ then you have $$$ to make it faster!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

My poly mount work fine only notice a small vibration over 100 mph.

Thank you all for the advice, i really do appreciate it! Thanks.
