Hi all, I got a GM 4T65E transmission in a '09 Impala with a 3.5L V6. Just did a OBDII scan for tranny codes since 4T65Es have an awful history. It comes up U0101 "lost communication with TCM " this means I can't see what's happening in the tranny. This could mean wiring / connector problems between modules stashed in the intake air plenum. However, just yanking cables out without a "heads up" could make it worse. Anyone worked on this problem before? Thanks!!
