Only code is inputs speed sensor and tcm code, whoever put the tranny on last put it on kinked and cracked the adapter plate and bell housing. I’m having both of those replaced and hoping the sensor fixes the shifting problem. it’s a 05 lly 4x4 and it shifts hard from 1-2 then is stuck in 2 but once it shifted perfect on the way to the shop any ideas other than sensor and the tcm has been changed only other thing I can think of is solenoids.
