The transmission Failure Mode Effects Management serves 3 purposes: Prevents invalid combinations of applied clutches that cause tie-ups Isolates a potential fault down to a specific pressure switch, solenoid or clutch Limits gears of operation based on the failure after the fault had been isolated	When failures occur the customer may complain of erratic shifting or transmission hanging in gear. This is normal for the Failure Mode Effects Management strategy. DETERMINE which gears are being commanded, and which gears are being avoided, and this will in turn point to a specific pressure switch, solenoid or clutch fault.
