External Controls

The transaxle external controls system consists of the following components:

- Selector lever assembly
- Selector lever cable and bracket
- Brake Shift Interlock Actuator (BSIA)
- Transmission Control Switch (TCS)

The selector lever controls the transaxle gear selection through the selector lever cable. When the selector lever is moved to the desired mode of operation it moves the selector lever cable which moves the manual control lever on the transaxle. This results in the desired gear selection. The selector lever knob controls the cable detent and selector lever locking position.

Range Selection





Brake Shift Interlock Actuator (BSIA)









Location

The BSIA is part of the selector lever assembly.

The brake shift interlock system prevents the selector lever from being moved out of PARK unless the requirements to do so are met. The ignition switch must be in the ON position and the brake pedal must be pressed. The brake pedal position is detected by the Brake Pedal Position (BPP) switch. In the event the vehicle will not come out of PARK, the manual release mechanism mechanically bypasses the electric portion of the brake shift interlock system allowing the selector lever to be moved out of PARK. The manual release mechanism is part of the selector lever assembly. If PARK is selected again, the selector lever will be locked again.

Drive with Grade Assist

Drive with Grade Assist





Drive with Overdrive (O/D) cancel and grade assist is activated when the Transmission Control Switch (TCS) is pressed. The TCS is located on the selector lever knob. When the TCS is pressed, the 6th gear or O/D upshift is prevented or the transaxle shifts down to 5th gear. The TCS is meant to be used when driving conditions cause excessive shifting from 6th to other gears such as hilly terrain, mountainous areas or when engine braking is required.

Grade Assist

- O/D is cancelled.
- The transaxle operates in gears 1 through 5.
- The Grade Assist lamp illuminates on the Instrument Cluster (IC).
- Improves vehicle handling in hilly terrain or mountainous areas by providing engine braking and extending lower gear operation on uphill climbs.

- Provides additional engine braking through the automatic transaxle shift strategy which reacts to vehicle inputs (vehicle acceleration, accelerator pedal, brake pedal and vehicle speed).

- The transaxle selects gears that provide the desired engine braking which is based on the vehicle inputs. Engine braking increases engine rpm.

Returning to DRIVE mode on flat terrain provides the best fuel economy and transaxle performance. The transaxle returns to O/D when the TCS is pressed again or the key is turned OFF.
