Shift Point Road Test

Shift Point Road Test

This test verifies that shift control valves are operating properly.

1. Bring engine and transaxle up to normal operating temperature.
2. Operate vehicle with shift control selector lever in O/D range.
3. Apply minimum throttle pressure and observe upshift speeds and speed at which torque converter clutch applies.
4. Stop vehicle and move shift control selector lever to D range.
Repeat Step 3.
Transaxle will make all upshifts except 3-4 and torque converter clutch apply should occur above 46 km/h (27 mph).
5. Press accelerator pedal to floor, wide open throttle (WOT). Transaxle 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 48km/h (30mph), move shift control selector lever from D range to 1 range (LOW) and remove foot from accelerator pedal. Transaxle should immediately downshift to second gear. When vehicle speed drops below 32 km/h (20 mph) transaxle should downshift into first gear.
7. If transaxle fails to upshift and/or downshift as outlined, refer to Quick Test.
