Overview:The Fuller Advantage transmission uses the X-Y Shifter to engage and disengage a gear based on the driver’s selected mode of operation. Gear engagement is achieved by activating the X-Y Shifter Gear Motor, which controls the fore-and-aft movement of the Shift Finger. Pushing the Shift Finger against one of the Shift Bar Housing Shift Blocks guides the Shift Yoke to engage the Sliding Clutch into a gear. The position of the X-Y Shift Finger is monitored by the Transmission Electronic Control Unit (TECU) by way of the X-Y Gear Position and Rail Position Sensors. Fault Code 73 is set when...

Overview:The Fuller Advantage Transmission Electronic Control Unit (TECU) communicates with the engine ECU over the J1939 Data Link. During every shift, the TECU receives speed and torque information from the engine and requests changes in speed or torque from the engine to synchronize shifts. If the engine does not respond to speed or torque commands and no J1939 communication fault codes are present, the fault is set. This fault can also be set if the TECU or engine ECU configuration settings are not correctly matched. Detection:TECU monitors the net torque output and calculates the synchronization speed required to shift efficiently....
