clunk when power shifting '04

I only get this when I really pull a hard 2/3rd or 3/4th under full acceleration. It's very loud, feels more like differential or axle movement rather than just wheel hop but I might be wrong. Is this a problem with '04 GTO's? Is there a correction?

sounds like a loose/broken transmission mount.

Say, I didn't think of the transmission movement, but I was under the impression is was coming from the rear end area. I will tune my ears a little and see if it's more up the middle.

it will sound like that but the best way to know for sure is to get underneath and check it out.

Thunk in the trunk t.s.b., take to dealership and they will add the bushing to help stop the noise.

When I took my 04 in for the Thunk-in-the-Trunk, I took a printed out copy of the tsb with me and told them "I was experiencing this issue". No problem and they fixed it.

most dealers wont argue if you walk in with a TSB. Its those that dont have one that meet resistance.
