Overview:This code indicates an electrical failure of the solenoids that control the pneumatic range valve. Detection:Starting at key-on and throughout operation, the Transmission Controller constantly measures this circuit. A failure mode 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 LO range or HI range. When the vehicle comes to a stop, an attempt to shift into LO range is made. Required Tools:1) Basic Hand Tools2) Digital Volt/Ohm Meter3) AutoSelect/AutoShift Troubleshooting Guide Possible Causes:1) Range solenoid coil open or shorted2) Damaged transmission harness3) Malfunctioning transmission...

Overview:This code indicates an electrical problem in the interia 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.
