AC60E AUTOMATIC TRANSMISSION / TRANSAXLE  AUTOMATIC TRANSMISSION SYSTEM(for 7GR-FKS)  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 "6" (S6 range) using the transmission control switch.

Moving the shift lever to "+" once raises the shift range by one, and moving the shift lever to "-" once lowers the shift range by one.
