Shift Point Road Test
This test verifies that the shift control system is operating correctly.
- Bring engine and transaxle up to normal operating temperature.
- Operate vehicle with selector lever in (D) range.
- Apply minimum throttle and observe speeds at which upshift occurs and torque converter engages using the shift speeds chart.
- 4. Stop vehicle, with the selector lever in the (D) range, press the overdrive cancel button. Repeat Step 3. Transaxle will make all upshifts except 3-4 and torque converter clutch apply should occur above 40 km/h (25 mph).
- 5. With vehicle speed above 43 km/h (27 mph), press accelerator pedal to floor, wide-open throttle (WOT). Transaxle should shift from third to second, or third to first, depending on the vehicle speed. The torque converter clutch should release.
- 6. With vehicle speed above 56 km/h (35 mph), move the 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 45 km/h (28 mph), transaxle should downshift into first gear.
- 7. If transaxle fails to upshift/downshift or TCC does not apply and release, refer to DIAGNOSIS BY SYMPTOM .
NOTE:
Shift speed ranges are approximate for all applications. For specific applications (engine, axle ratio and application) refer to the Automatic Transmission Specification Issue available from Ford Customer Service Division.
