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.
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.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
