FLUID COOLER FLUSHING
Flushing Procedure
1. Drain the fluid from the transaxle and refill the
transaxle with new transaxle fluid. Refer to ”Fluid
Drain Procedure” in this section.
2. Let the engine idle for 5 minutes.
3. Drain the fluid from the transaxle and refill the
transaxle with new transaxle fluid. Refer to ”Fluid
Drain Procedure” in this section.
CONTROL CABLE ADJUSTMENT
Adjustment Procedure
The various shift control cable positions must match at the
shift control lever in the vehicle and at the selector lever
on the transaxle to provide proper transaxle shifting.
Place the shift control lever in the PARK position and
check the selector lever connection to verify that it is in the
forward most position. If it is not, the following adjustment
must be performed:
1. Disconnect the negative battery cable.
2. Remove the floor console. Refer to Section 9G,
Interior Trim.
3. Place the shift control lever in the PARK position.
4. Loosen the control cable adjusting nut.
5. Move the Transmission Range (TR) switch lever
counterclockwise until stopping the lever.
