hi everyone i have a 91 firebird 3.1 v6 and when i really gun it from a dead stop there is a loud clunk but then it is fine anytime after, except when i am in second and i floor it and it kicks down to first. I figured it was the u joints so i canged the front and back u joints. It has the stock trandmission and stock rear end. When it happens it feels like it is under the console. Any ideas would help, thanks

Get the front of the car on ramps or stands and check the transmission and torque arm mount.

Its your transmission mount. I replaced mine and it fixed the clunk noise.

Before you purchase anything, crawl under the car and take a peek. You may well have that awful and very expensive fluid-filled mount. If so, I'd recommend, swapping in a used cross member and a standard mount.

How will i be able to tell if it is the fluid mount?

I think they are round.

Careful. I stripped my trans mount bolt replacing it a couple days ago still haven't gotten it out.

could also be a missing rubber bushing in the rear or front suspension.

I had the same situation but , I just put the car back together with 383 and b&m built trans and brand new mount from Orielly Auto Parts and tore that mount in half within 5 brisk drives!...so I replaced it with the black poly performance one ..bad thing is I also stripped a bolt hole to the trans installing that thing so I havent got to try this out yet also just ordered matching torque arm bushing I see that it is done with ..?wonder if that caused the new mount to tear in half! oh well

I may have the same problem, Im going to get some t-mounts this weekend. I had this banging noise coming from the passenger floor board, sounded like exhaust hitting floor. when turning left and accelerating. I installed wheel bearings, well i bought some, they didnt mach up so i took them back.they were ok. . "i got on it" going straight an it sounded like the trans hit the pavement.
