Control Module: Description and Operation
Description
DESCRIPTION
The transmission control module (TCM) receives, processes and sends various digital and analog signals related to the automatic transmission. In
addition, it processes information received from other vehicle systems, such as engine torque and speed, accelerator pedal position, wheel speed,
kick-down switch, traction control information, etc.
The TCM is located forward under the driver's seat (1) and is connected to other control modules via a CAN bus. It controls all shift functions to achieve
smooth shift comfort in all driving situations considering:
-
Vehicle speed.
-
Transmission status.
-
Position of selector lever.
-
Selected shift range.
-
CAN signals.
-
Engine Status.
Engine speed limits may be reached in all gears with full throttle or in kick-down operation. In forward driving, the shift range of the forward gears can
be adjusted by the operator by tipping the selector lever to the left or right (AutoStick). However, the TCM features a downshift inhibitor to prevent the
engine from overspeeding.
