Shift Point Road Test

Shift Point Road Test

NOTE: Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.

The Shift Point Road Test and Torque Converter Clutch Operation Test provide diagnostic information on transaxle shift controls and torque converter operation.

This test verifies that the shift control system is operating correctly.

1. Bring engine and transaxle up to normal operating temperature.

2. Operate the vehicle with the selector lever in the D position (Overdrive (O/D) switch ON).

3. Apply minimum throttle and observe the speeds at which upshift occurs and torque converter engages. Refer to the following Shift Speeds Chart for the appropriate final drive ratio. (Also refer to the Automatic Transaxle specification Issue.)

4. Stop the vehicle. Select the D position ( O/D switch OFF). Repeat Step 3. The transaxle will make all upshifts, except 3rd to 4th, and Torque Converter Clutch (TCC) apply should occur above 80 km/h (50 mph).

5. Press the accelerator pedal to the floor, Wide Open Throttle (WOT). The transaxle should shift from 3rd to 2nd, or 3rd to 1st, depending on vehicle speed, and TCC should release.

6. With vehicle speed above 48 km/h (30 mph), move the selector lever from D position to L position and release the accelerator pedal. The transaxle should immediately downshift to 2nd gear. When vehicle speed drops below 32 km/h (20 mph), the transaxle should downshift into 1st gear.

7. If transaxle fails to upshift/downshift or TCC does not apply/release, refer to Diagnosis By Symptom Diagnosis By Symptom for possible causes.
