Shift Paddle Switch Circuit: Description

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.

When the shift lever is in M, it is possible to make use of the highest engine speeds by holding the vehicle in a gear. Gear hold control means that gear shifts will not be performed as long as the paddle switches are not operated in either the "+" (UP), or "-" (DOWN) direction.
