AUTOMATIC TRANSMISSION SYSTEM Shift Paddle Switch Circuit

DESCRIPTION

When moving the shift lever into the M position using the transmission control switch, it is possible to switch the shift range position between "1" (first range) and "6" (sixth range).

Shifting up "+" once raises one shift range position, and shifting down "-" lowers one shift range position.

When the shift lever is in D, operating the "-" side shift paddle switch will cause the transmission to enter fixed range mode which restricts the highest gear. By operating the shift paddle switches "+" (UP) or "-" (DOWN), the shift range can be changed.

When the vehicle is being operated in D position (fixed range mode), if the vehicle is stopped or the accelerator pedal is kept steady for a certain period of time with the transmission in the same gear, the vehicle will change back automatically to normal D position operation.
