I know the LS4 trans in complete crap (basically a v6 trans). But Im curious to see if anyone has built or modded any of those cars? Just saw a GXP today that sounded pretty mean, which made me think of this. :noes:

Yeah there are quite a few with cams and there was a company making headers for them at one time, there is also a company that makes a turbo kit for them, still the trans is the weak link and takes lots of money to make it handle decent power

It takes alot of money to make the trans hold stock power haha. I know a couple cars that have their problems with the trans.

If GM was thinking, put in a strong trans, and made them RWD those cars would be legendary.

If you get one, leave it alone.

They're nice spunky DDs, but drive it like you stole it and the trans will give up the ghost quickly.

If only they brought over the pre-G8 Holdens over with the "Ecotec" 3800 from down under.
