Type of Fault: FMI Description: Fault Condition: Possible Symptoms: Possible Cause

This document provides fault codes and descriptions for issues with the transmission control unit of a vehicle. FMI 11 indicates a blocked engagement of first gear, which prevents the first gear from engaging and results in no torque or incorrect gear selection. FMI 12 signifies a blocked engagement of reverse gear, meaning reverse cannot engage and the system will repeatedly try to engage it while the gear lever is in reverse. Possible causes for both issues include problems with the control housing detent assembly, transmission control module, seals, solenoid valves, gears, engagement clutches, piston rods or gear wheels.
