Have a 2008 range Rover. Getting the limited gear available and special programs not available error on dash. Tried clearing the codes and pulling the battery and the message comes back as soon as you turn the key to on. I also tried changing transmission pan, filter and connector sleeve. Also dropped the valve body and replaced the four tube seals and the bridge seal. Cleaned and refitted the transmission wire harness, no damage seen. Used SDD tool and got a P0657-00 on the TCM. Actuator supply voltage A - circuit/open. Any idea what this could be?
