Shift Point Road Test: Notes
WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, 2008 Ford E450 Super Duty, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Always drive the vehicle in a safe manner according to driving conditions and obey all traffic laws.
This test verifies that the shift control system is operating correctly.
- Bring engine and transmission up to normal operating temperature.
- Operate the vehicle with the transmission selector lever in Overdrive (Circle D) range.
- Apply minimum throttle and observe the speeds at which the upshift occurs and the torque converter engages. (Refer to the shift speed chart.)
- Press the accelerator pedal to the floor, Wide Open Throttle (WOT). The transmission should shift from 6th to 5th gear or 5th to 3rd gear depending on vehicle speed. Torque Converter Clutch (TCC) should disengage and then reapply.
- With the vehicle speed above 48 km/h (30 mph), move the selector lever to the manual 3rd gear position. The transmission should immediately have a 5th to 3rd shift. When vehicle speed drops to 32 km/h (20 mph) a 3 to 1 shift should occur.
- If the transmission fails to upshift/downshift or if the TCC does not apply and release, refer to Diagnosis By Symptom for concern diagnosis.
