Overview:When available and enabled, Neutral Coast Mode allows the transmission to disengage the driveline by pulling out of gear on slight downhill grades, where little to no engine power is required, when the vehicle is in cruise control and the transmission is in Drive Mode. Neutral Coast may refer to one of several different systems that control various elements of vehicle cruise control logic. The transmission controlled version is an Eaton proprietary logic where the transmission makes the decisions when the driveline should be engaged or disengaged. Engine/J1939 controlled systems use an engine or another vehicle ECU to determine the...

Overview:The Fuller Advantage transmission uses the X-Y Shifter to engage and disengage gears based on the driver’s selected mode of operation. Gear engagement and disengagement 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 or disengage the Sliding Clutch into or out of a gear. The position of the X-Y Shift Finger is controlled and monitored by the Transmission Electronic Control Unit (TECU) by way of the X-Y Gear Position and Rail...

Overview:The Fuller Advantage transmission may be equipped with an analog shift control device. The Transmission Electronic Control Unit (TECU) supplies the analog Shift Control Device a 5-volt reference through OEM wiring. This voltage is reduced by resistive ladder circuitry in the shift device, based on the position the driver selects. The return voltage to the TECU indicates the position of the Shift Lever. Fault Code 83 indicates the TECU did not identify a Shift Lever position. Detection:The TECU monitors Shift Lever position by supplying voltage to the Shift Lever and measuring the returned voltage. When the return voltage received by...
