CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM Transmission Control Switch Circuit

DESCRIPTION

After moving the shift lever to M, it is possible to change the shift range between M1 and M7 using the transmission control switch. Moving the shift lever to "+" once raises the shift range by one, and moving the shift lever to "-" lowers the shift range by one.
