Title: AB60F AUTOMATIC TRANSMISSION: AUTOMATIC TRANSMISSION SYSTEM: Transmission Control Switch

Circuit; 2015 MY Tundra [08/2014 - ]

Transmission Control Switch Circuit

DESCRIPTION

When moving the shift lever into the S position using the transmission control switch, it is possible to switch the

shift range position between "1" (1st range) and "6" (6th range).

Shifting to "+" once raises the shift range position by one, and shifting to "-" lowers the shift range position by

one.
