Shift Point Road Test

Shift Point Road Test






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

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

2. Operate vehicle with transmission selector in (D) range.

3. Apply minimum throttle and observe speeds at which upshift occurs and torque converter engages. Refer to the following Shift Speeds chart.

4. Stop the vehicle. Depress transmission control switch (TCS) to activate (D) range. Repeat Step 3. Transmission will make all upshifts except 3-4 and torque converter clutch apply should occur above 46km/h (27mph).

5. Press accelerator pedal to floor, wide open throttle (WOT). Transmission should shift from third to second, or third to first, depending on vehicle speed, and torque converter clutch should release.

6. With vehicle speed above 48 km/h (30 mph), move transmission range selector lever from (D) range to (1) range (LOW) and release accelerator pedal. Transmission should immediately downshift to second gear. When vehicle speed drops below 32km/h (20mph), transmission should downshift into first gear.

7. If transmission fails to upshift / downshift or torque converter clutch does not apply / release, refer to Diagnosis by Symptom Index for possible causes. Symptom Related Diagnostic Procedures
