| Description |
Transmission Control Module (TCM) is the automatic
Transmission's brain. The module receives and processes signals from
various sensors and implements a wide range of Transmission controls to
ensure optimal driving conditions for the driver.
TCM is programmed for optimal response to any on-road
situation. In the event of a transmission failure or malfunction, TCM
stores the fault information in memory so that the technician may
reference the code and quickly repair the transmission.
Functions
| • |
Monitors the vehicle's operating conditions to determine the optimal gear setting. |
| • |
Performs a gear change if the current gear setting differs from the identified optimal gear setting. |
| • |
Determines the need for damper clutch (D/C) activation and engages the clutch accordingly. |
| • |
Calculates the optimal line pressure level by constantly monitoring the torque level and adjusts the pressure accordingly. |
| • |
Diagnoses the automatic transmission for faults and failures. |
