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 automati-
cally increases or decreases engine speed. When
engine speed is correct, the transmission engages
the next gear and signals the engine controller to
resume operation.
The AutoShift system consists of the following com-
ponents:
•
The Gear Display Module (
Fig. 8.4
) 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.
•
The Driver Command Console (DCC) replaces
the shift lever and controls the transmission’s
shift patterns.
