The transaxle selector lever control linkage consists of:
- a selector lever cable that connects the transaxle range selector lever to the selector lever assembly.
- a Brake Shift Interlock Actuator (BSIA) that is integral to the selector lever assembly.
The selector lever assembly:
- locks the transaxle range selector lever in the PARK position when the ignition switch is in the lock position.
- requires the transaxle range selector lever to be in the PARK position to turn the ignition switch to the lock position.
Vehicles equipped with a 2.5L engine have a Transmission Control Switch (TCS) which is 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.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
