transmission help!!

I have a 1988 GTA with a few mods on it and a small problem. Everytime i really romp on it i get a loud thud from the front of the drivline hitting up agaisnt the floorboard. I think its my transmission mount, could it be something else? Any advice or tips would be great.

Get an Energy Suspension one they are generally around 25-30 bucks if that. You should be able to get them at a local parts store or speed shop. I know Pep Boys used to have them. hth. I have had the same one for about 9 years now.

Re: transmission help!!

Yes, what Cliff said. They aren't expensive for the poly ones. They aren't too hard to install either.
Take care
Mike
