Eaton Fuller 10-speed AutoShift transmissions have 10 forward speeds and two reverse speeds. The transmission consists of a 5-speed front section and a 2-speed rear section. The driver must use the clutch to start and stop the vehicle.

The driver does not need to break torque or increase or decrease engine speed to synchronize the shift. The transmission signals the engine controller when to break torque and the engine controller automatically increases or decreases engine speed. When engine speed is correct, the transmission engages the next gear and signals the engine controller to resume operation.

Warning: When starting or stopping on hills and grades, use extra care to prevent the vehicle from rolling back. A rollback accident could cause death, serious personal injury, or property damage.

The AutoShift system consists of the following components:

  • The SmartShift control paddle on the steering column. See Fig..

  • The gear display module (see Fig. ) mounted on the dashboard indicates the current gear position or transmission status. The display also flashes the next gear to be engaged while the transmission is in neutral during a gear change.

    Note: To upshift manually, pull the lever up (towards you). To downshift manually, push the lever down (away from you).

    • The shifter mechanism performs shifts at the front portion of the transmission. It preselects the shift to neutral and completes the gear change after driver input.

    • The Electronic Control Unit (ECU) includes two controllers: a transmission ECU and a system ECU. The transmission ECU controls all transmission shift functions and the system ECU manages all vehicle interfaces for transmission shift functions.

    • An electronic range valve, controlled by the transmission ECU, is used to perform range shifts.
