Shift Point Road Test
WARNING: This page is about a different car, the 2009 Mercury Milan and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
This test verifies that the shift control system is operating correctly.
- Bring engine and transaxle up to normal operating temperature.
- Operate the vehicle with the selector lever in the D position.
- Apply minimum throttle and observe the speeds at which upshift occurs and torque converter engages. Refer to the following Shift Speeds Chart for the appropriate final drive ratio.
- Press the accelerator pedal to the floor, Wide Open Throttle (WOT). The transaxle should shift from 3rd to 2nd, or 3rd to 1st, depending on vehicle speed, and Torque Converter Clutch (TCC) should release.
- With vehicle speed above 48 km/h (30 MPH), move the transaxle range selector lever from D position to 1st position and release the 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 1st gear.
- If transaxle fails to upshift/downshift or TCC does not apply/release, refer to Diagnosis By Symptom for possible causes.
