Shift Point Road Test

Use the following road test procedure to verify shift control valves are operating correctly:

1. Drive vehicle to bring engine and transaxle to operating temperature. Operate vehicle with gear selector in "OD" position.
2. Apply MINIMUM throttle and observe and record upshift speeds. See appropriate SHIFT SPEEDS SPECIFICATIONS  table. Observe and record speed at which converter clutch applies.
3. Stop vehicle and move gear selector to "D" position. Repeat step 2). Transaxle should make all upshifts except 3rd-to-4th. Torque converter lock-up should occur above 27 MPH (43 km/h).
4. Depress throttle pedal to Wide Open Throttle (WOT) position. Converter clutch should release and transaxle should downshift to next lower gear.
5. With vehicle speed greater than 30 MPH (48 km/h), move gear selector from "D" to "1" position and release accelerator pedal. Transaxle should immediately downshift to 2nd gear. When vehicle speed drops to less than 20 MPH (32 km/h), transaxle should downshift into 1st gear.
6. If transaxle fails to shift as described above, perform EEC-IV or EEC-V QUICK TEST procedure. See procedures in appropriate ELECTRONIC CONTROLS article.
