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.

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.

Apply minimum throttle and observe speeds at which upshift occurs and torque converter engages using the shift speeds chart.

With vehicle speed above 43 km/h (27 mph), press accelerator pedal to floor, Wide Open Throttle (WOT). The transaxle should shift from 4th to 3rd, or 4th to 2nd, depending on the vehicle speed. The Torque Converter Clutch (TCC) should release.
With vehicle speed above 56 km/h (35 mph), move the selector lever from D (DRIVE) range to L (LOW) range and remove foot from accelerator pedal. The transaxle should immediately downshift to 2nd gear. When vehicle speed drops below 32 km/h (20 mph), the transaxle should downshift into 4th gear.
If the transaxle fails to upshift/downshift or TCC does not apply and release, refer to Diagnosis By Symptom for possible causes.
