When conditions are right for a shift, the transmission Electronic Control Unit (ECU) notifies the driver with a tone from the Driver Command Console (DCC). See Fig.. The driver, when ready to shift, breaks torque and the transmission goes to Neutral. The driver then either increases or decreases engine speed to synchronize the shift. When engine speed is correct, the transmission shifts automatically.

The AutoSelect system consists of the following components.

  • The Driver Display Module, or DDM (see Fig.), mounted on the dashboard, indicates gear position and the direction engine rpm needs to go for the next gear engagement. When the gear select lever is in the "D" position, the display module indicates what the driver must do to engage the next gear (decelerate or accelerate) by down and up arrows. When the gear number is solid on the display, that gear is fully engaged. When the gear number is flashing the transmission is either out of gear, waiting for the engine and transmission to synchronize, or the next gear engagement is in process.

  • The Driver Command Console, or DCC (see Fig.), replaces the shift lever and controls the transmission's shift patterns. There are indicators for the three forward positions: drive, hold, and low, plus reverse and neutral positions. Shift tone volume buttons and service and wait lamps are also located on the console. The gear select handle contains upshift and downshift buttons and a gear select lever detent button.

  • The shifter 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) consists of 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.
