PURPOSE
The Transmission Control Unit (TCM) receives various sensor signals and determines vehicle operating conditions. It then sends control signals
to each solenoid according to the preset gearshift characteristic data, lock-up operation data, and transfer clutch torque data (duty ratio).
LOCATION
Inside left rear quarter panel.
OPERATION
Shift pattern is selectable automatically between a normal pattern suitable for ordinary economy running and a power pattern suitable for climbing
uphill or rapid acceleration. In the power pattern, the shift down point and shift up point are set higher than those of the normal pattern.
When the power pattern is selected, the POWER indicator light in the meter lights up.
