05 Base Auto transmission problems
So, I bought a 2005 base C6 roller, I had another 05-donor car for the drivetrain. The car has heads and cam 6.2l ls3 short block with 243 heads. running a Lingenfelter module to account for reluctor difference. transmission is stock. Ever since I built the car it shifts 1-2 fine upon shifting into 3rd it acts like it's in neutral before falling back down into second. I have since replaced the transmission and am having the exact same issue. I also tried the transmission control module from the other car. Not sure if it could be wiring harness related or if I really have managed to get two transmissions with the exact same problem.

What I learned is the 05 Automatic was only installed in the 05, after that different transmission used believe it's 4L65E.
