Hi forum,
I have recently transplanted a LSA and 6L80 combination.
The combination was perfect before the transplant, and I have not made any calibration changes in the meantime.
The OS is from a 2013 Camaro - 12653669
The TCM OS is - 24264923
As mentioned, these were matched and cooperating before the engine and gearbox were moved.
Now I am faced with the code U0101 Lost communication with TCM.
I have verified wiring from the TCM.
The ECM is communicating with the dash etc all working.
I can read the calibration from TCM, ECM both fine which means the TCM is powered up and communicating on the canbus.
I have tried various combinations of disconnecting the battery, pulling TCM fuse with no luck.
I have tried a write entire of the same ECM and TCM files that were already loaded.
As some extra info, the only other code current is P0315 crankshaft position not learned (Never seen this code before so wondering if its related)
Anyone got ideas, I'm stumped!
