AB60F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSMISSION SYSTEM: Transmission Control Switch Circuit
- Transmission Control Switch Circuit
DESCRIPTION
When moving the shift lever to S using the transmission control switch, it is possible to switch the shift range between "1" (1st range) and "6" (6th range).
Shifting to "+" once raises the shift range by one, and shifting to "-" lowers the shift range by one.
