Aside from going into limp mode, any other symptoms? Slipping? Banging into gear? My BA (210,000 kms also) started going into limp mode but showed no other signs of problems and it ended up being a faulty solenoid. It only threw codes when it was scanned whilst in limp mode - if I shut it off and restarted and then scanned, codes weren't being logged. Try and keep notice on when it does it - if it seems to happen during a shift, it could be a solenoid.
