Re: Transmission fluid leak (help wanted)
If the transmission module gets changed with the transmission, you may need a reflash. Modern automatic transmissions are very complex compared to the old schools ones I grew up with, I'd take it to a reputable transmission shop, and leave the other shop to the engine issues. It's clear that they aren't going to help you.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
