I believe the transmission rebuild has solved the mechanical problem but the warning lights remaining suggest to me that the TCU needs reflashing. Can the TCU be reset (flashed, reprogrammed, etc.) or are the previous faults "permanently" set? Can you also explain to me the communication line between the two (2) bank ECUs, the two(2) cat ECUs and the single (1) TCU? Which control unit is responsible for triggering the SDL? the CEL? Your help is appreciated.
