Shift Point Road Test

WARNING: This page is about a different car, the 2008 Ford RV Cutaway, 2008 Ford Econoline, and 2008 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Shift speed ranges are approximate for all applications. For specific applications (engine, axle ratio, tire size and application), refer to the Automatic Transmission Specification Issue, available from Ford Customer Service Division.

This test verifies that the shift control system is operating correctly.

  1. Bring engine and transmission up to normal operating temperature.
  2. Operate vehicle with selector lever in Overdrive (Circle D) position.
  3. Apply minimum throttle and observe speeds at which upshift occurs and torque converter engages, refer to Shift Point Road Test .
  4. With the transmission in OVERDRIVE (4th gear), press the transmission control (TC) switch. The transmission should downshift to 3rd gear. Release the accelerator pedal; engine braking should occur.
  5. Press accelerator pedal to floor, wide open throttle (WOT). Transmission should shift from 3rd to 2nd gear or 3rd to 1st, depending on vehicle speed. Torque converter clutch (TCC) should disengage and then reapply.
  6. With the selector lever in Overdrive (Circle D) position and speed above 80 km/h (50 mph) and less than half throttle, move the selector lever from Overdrive (Circle D) position to manual 2 position and remove pressure from the accelerator pedal. Transmission should immediately downshift into 2nd gear. With vehicle remaining in manual 2 position, move the selector lever into manual 1 position, and release accelerator pedal. Transmission should downshift into 1st gear at speeds approximately below 45-56 km/h (28-35 mph).
  7. If transmission 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 booklet. Do not exceed local speed laws.
