Transmission Control Switch Circuit

U241E AUTOMATIC TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: Transmission Control Switch Circuit
- Transmission Control Switch Circuit

DESCRIPTION

After moving the shift lever to S using the transmission control switch, it is possible to change the shift range between "1" (1st range) and "4" (4th range).

Shifting to "+" once raises the shift range by one, and shifting to "-" lowers the shift range position by one.
