TCM failure
The early nineties Mitsubishi made TCMs are quality computers with the exception of the failing Rubicon electrolytic capacitors that were used to equip these electronic control units.
Engine computer or transmission computer, these will break down after five years or so, some last a few years longer but they are basicaly on bowored time. TCM or TCU failure usually appears as "fail safe mode"- the car drives in second or third gear only.
