Have Transmission Questions? Ask a Mechanic for Answers ASAP
Hi,Are you able to get the vehicle to an auto parts store for a free scan to at least see what the engine light fault is? This won't tell us the transmission fault (the flashing N light indicates a problem there), but it may be related and could accelerate the diagnosis considerably.
The N light operates as a "check engine" light of sorts for the transmission. It serves two different functions depending on the speed at which it flashes.If the light is flashing at 1Hz (about one time per second) it is indicating that a trouble code is stored in the transmission controller. This is the transmission equivalent to the check engine light.
If the light is flashing at 2Hz (about twice per second) it is indicating that the transmission temperature has gotten too high.
The latter is rarely the case, and would have gone away in most instances once the vehicle was allowed to rest; only the former instance would continue with the light flashing.
The transmission faults need a specific scan tool to read... a generic OBD reader can not retrieve them, it has to have Mitsubishi transmission controller access. However the check engine light may be related... there are several transmission faults that can set which will turn on the check engine light with a related code (for example many solenoid faults, speed sensor faults). This is why scanning the engine light is a good idea here, since the transmission codes you would have to pay a repair shop to scan (auto parts stores do not have the proper scan tool to read the embedded transmission faults).
