Transmission Control Switch (TCS)-2.5L
WARNING: This page is about a different car, the 2011 Mercury Milan, 2011 Lincoln MKZ, and 2011 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Vehicles equipped with a Transmission Control Switch (TCS) have a momentary contact switch located on the selector lever knob that allows the driver to cancel the operation of Overdrive (O/D) and provides grade assist.
Grade Assist
- Improves vehicle handling in hilly terrain or mountainous areas by providing additional engine braking and extends lower gear operation on uphill climbs.
- Additional engine braking is provided through the automatic transaxle shift strategy which reacts to vehicle inputs including vehicle acceleration, accelerator pedal, brake pedal and vehicle speed.
- The transaxle will select gears that will provide the engine braking desired, based on the vehicle inputs, this will increase engine rpm during engine braking.
It is recommended to return to DRIVE mode on flat terrain to provide the best fuel economy and transaxle function. The transaxle returns to O/D and grade assist is cancelled when the TCS is pressed again.
