So I'm having a TCC problem and after replacing the solenoid didn't fix it, a tranny guy suggested changing the PCM. I have one, but it's from the LT1. Is this swap okay or are there differences in the computer? Thanks

Computers are the same if it's from the same year (94, 95 OBD1 - 96 OBD2). However the programming is different. You'll need to have that adjusted.
