0605 PCED Powertrain Control Module ROM error Internal PCM failure Internal PCM failure
P0743 which is the Torque Converter Electrical Circuit
To replace the pack you have to drop the trans pan. If you find a lot of metal fragments in the pan/on the magnet then don't even bother changing the solenoids...you have internal failure. A lot of times the solenoids will get clogged with metal & trip a code
The fault might be a wiring harness fault, a faulty PCM, or a faulty solenoid/pack in the transmission.
