i dont know how mechanically inclined you are but here is some more info/links
this is the auto manual:

about 1/3rd down it starts on the awd auto
this is how to pull the tcu code manually:
TCU Codes
i know it says dsm but its the same diag plug and procedure
your ecu is located behind the climate control system, this is how to get to it:
Stealth 316 - ECM Removal
just imagine the pics flipped since we have rhd
pay close attention to the caps, mine looked fine but were actually leaking underneath where you couldnt see it unless you took them off. same goes for the tcu, pull it open it and inspect it.
the tcu is on the floor behind the ecu.
anymore questions just ask.
