AUTOMATIC TRANSMISSION SYSTEM (for 1KD-FTV) - Transmission Control Switch Circuit


DESCRIPTION

After moving the shift lever to S, it is possible to switch the shift range between "1" (S1 range) and "5" (S5 range) using the transmission control switch.
Shifting to "+" once raises the shift range by one, and shifting to "-" once lowers the shift range by one.
