PROBLEM

The existing 244-3114, 258-8987, 425-4563, 522-0906 Valve Group (whichever is installed) for transmission clutches 1 through clutch 6 and the Torque Converter Lock-Up Clutch (LUC) can fail on certain 793F Off-Highway Trucks.

If the existing modulating valve fails, it can result in failed fill time and engagement pressure calibrations. Additionally, it can result in erratic clutch and LUC pressures causing premature failure of these clutches.

ACTION REQUIRED

Replace the existing clutch 1 through clutch 6 modulation valves on 793F Off-Highway Trucks (244-3114, 258-8987, or 425-4563 Valve Group) with the 562-6148 Modulation Valve. The Torque Converter LUC modulation valve (244-3114, 425-4563 or 522-0906 Valve Group) should be replaced with the 562-6148 Modulation Valve or 591-6918 Modulation Valve depending upon whichever valve is installed.

Note: The 562-6148 has a DT connector and the 591-6918 has an ampseal connector. Please ensure you use the correct valve based on the applicable truck harness.

Group 1, 2, 4, 7, 8: 595-3443 power train software or latest available on SIS Web must be installed when replacing the modulation valves. This software must be installed prior to the calibration of the modulation valves.

Group 3, 5, 6: 588-6190 power train software or latest available on SIS Web must be installed when replacing the modulation valves on machines not running in fully autonomous configuration. This software must be installed prior to the calibration of the modulation valves.

Refer to the Service Manual as required to replace the modulating valves.

Refer to the Service Magazine, M0120605, "New Software (2020.1 Bundle) is Now Used for Certain 793F Large Off-Highway Trucks" for additional information about the 595-3443 power train software.

Refer to the Service Magazine, M0112569, "Improved Transmission Software and Electronic Control Group are Now Used on Certain 793F CMD Off-Highway Truck" for additional information about the 588-6190 power train software.
