the car will run but only in 3rd gear i do believe. the tcu isn't throwing any codes and where do i find parts for this car it's not easy
transmission is stuck in safe mode how do i get it out of safe mode on 1991 Mitsubishi 3000GT
Check that the transmission fluid level is correct. Parts can be got on line from sources like www.rockauto.com but you are right the dealer has discontinued a lot of parts for the 3000GT, great car!
