AUTOMATIC TRANSAXLE SYSTEM Shift Paddle Switch Circuit

DESCRIPTION

When the shift lever is in M, the shift range can be changed using the shift paddle switches. It is also possible to select the shift range when the vehicle is being driven with the shift lever in D by operating the shift paddle switches.
