I'm looking to swap a 4L80E into a 06 Trailblazer SS wiht a E40 PCM T42 TCM. Is this possible? Can't get a segment swap on these PCMs. So if it's possible I'm guessing it would take some tuning!
I believe the 06 Trailblazer SS has the I.S.S so that shouldn't be a problem, but I thought I read that the 2-3 solenoid is different or PWM on the 4L80E. Can that be tuned out?
