Features
• The TCM selects and determines the shift diagram based on the results of the range and driving mode
judgements. Then, based on the shift diagram, the TCM sends the signal to the duty-cycle type solenoid valves
and the ON/OFF type solenoid valves, according to the VSS signal and the throttle opening signal, to perform
shifting.
