Overview:Fault Code 43 indicates an electrical failure of the solenoids that control the range shift. Detection:Starting at key on and throughout operation, the Transmission Controller constantly measures this Range Valve circuit. A failure of short to battery, short to ground or open circuit is detected. Fallback:This fault causes a 5-speed fallback and the transmission stays in either low range or high range. When the vehicle comes to a stop, an attempt to shift into low range is made. Possible Causes:1) Range Valve2) Transmission Harness3) Transmission Controller Shop Talk:Key on. If the fault is present, the system should automatically detect the...

Overview:Fault Code 44 indicates an electrical failure of the solenoid that controls the pneumatic Inertia Brake. Detection:Starting at key on and throughout operation, the Transmission Controller constantly measures this circuit. A failure mode of a short to battery, short to ground, or open circuit is detected. Fallback:There is no fallback associated with this failure; however, it may be difficult to perform an initial engagement due to a poorly adjusted clutch. Also, hill shifting performance may be reduced. Possible Causes:1) Inertia Brake Solenoid2) Transmission Harness3) Transmission Controller Shop Talk:Key on. If the fault is present, the system should automatically detect the...
