This test verifies the shift control system is operating correctly.
- Bring engine and transmission up to normal operating temperature.
- Operate vehicle with the selector lever in the D position.
- Apply minimum throttle and observe speeds when an upshift occurs. Refer to the SHIFT SPEEDS CHART in this article.
- With the selector lever in the D position and speed above 80 km/h (50 mph) and less than half throttle, move the selector lever from the D position to manual 2 position and release the accelerator pedal. The transmission should downshift into 2nd gear. With the transmission remaining in the manual 2 position, move the selector lever into the manual 1 position and release the accelerator pedal. The transmission should downshift into 1st gear at speeds below approximately 45-56 km/h (28-35 mph).
