Overdrive (O/D) OFF

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

The Overdrive (O/D) OFF Transmission Control Switch (TCS) is a momentary contact switch located on the end of the selector lever which is used along with the O/D OFF indicator lamp Transmission Control Indicator Lamp (TCIL). When pressed, the O/D OFF switch sends a signal to the PCM to only allow automatic upshifts that include 5th gear. O/D, or 6th gear, is disabled during O/D OFF mode. Pressing the O/D OFF switch again restores automatic upshifts from 1st through 6th gears.
