OverviewFault Code 28 indicates either an electrical or mechanical failure in the wet clutch system. Detection:1) Starting at key on and throughout operation, the Transmission Controller constantly monitors this circuit. A failure of short to battery, short to ground or open circuit sets the fault code Active.2) When the wet clutch is locked after urge to move, engine speed and Input Shaft speeds are compared. If the engine speed is significantly higher than the Input Shaft speed for a period of 5 seconds, the wet clutch is slipping. Fallback:There is no fallback mode; however, if the failure mode is open...

Overview:Fault Code 31indicates an electrical failure of the Momentary Engine Ignition Interrupt Relay (MEIIR) circuit. Detection:The fault is detected during power up. The Shift Controller checks the MEIIR circuit every time the system is powered up. If the electrical characteristics of the circuit are incorrect, the fault code is set. Fallback:There is no fallback associated with this failure; however, if the engine speed flares uncontrollably while the transmission is in a gear, the transmission may not be able to achieve neutral if it is selected due to a torque lock condition. Possible Causes:1) OEM wiring2) Electrical failure in the MEIIR...
