My dealer rocks.... (TSB)
 

Called my dealer yesterday about the "thunk in the trunk" TSB and they were great. They're ordering the parts and scheduling me whenever I want to come in. Totally awesome. Just wondering if anyone else is having such great luck with the GTO/dealer??? They weren't even aware of this TSB yet, and they've sold a couple along with 3 others sitting on their lot. Just thought I'd share my good news :D

My local dealer ordered the parts last week. They called today to let me know that they were in. I go have them installed tomorrow. Everything is going smoothly!!!
:chug:

what thunk in the trunk?

The loud clunk you hear when you shift hard in 6speed cars. Yours might not have it if its VIN was after the braking point. Go to www.ls1gto.com and check out the drivetrain section. There is a post in there all about.

**Thanks to DANLS1 for the help!!! My car is going in friday to get the fix!!

Shifting Clunk
 

Did they tell you what is causing the clunk noise?
