Transmission Control Module (TCM) Control Function

In automatic gear shift control, based on each gear shift pattern, Shift Solenoid A (SSA) and Shift Solenoid B (SSB) turn ON or OFF and Shift Solenoid C (SSC), Shift Solenoid D (SSD), Shift Solenoid E (SSE) and Shift Solenoid F (SSF) are operated linearly according to information that includes vehicle speed, the degree to which the accelerator is open and brake signals. For the gear and solenoid operation chart, refer to SPECIFICATIONS .

The Transmission Range (TR) sensor is built in the TCM, it detects the automatic transmission range information via the Hall-effect sensor and outputs the information to the TCM. The TCM reads the voltage and adjusts the automatic transmission range.
