Shift Point Road Test: Notes
WARNING: This page is about a different car, the 2005 Ford Pickup, 2005 Ford F550 Super Duty, 2005 Ford F450 Super Duty, and 2005 Ford Cab & Chassis. 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.
NOTE:
If equipped, turn the power take-off (PTO) unit off for correct test results. For a description of PTO operation, refer to TRANSMISSION ELECTRONIC CONTROL SYSTEM .
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 range selector lever in (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). The transmission should shift from sixth to fifth gear or fifth to third, depending on vehicle speed. Torque converter clutch should disengage and then reapply.
- With the vehicle speed above 48 km/h (30 mph), move the transmission range selector lever to manual third gear. The transmission should immediately have a fifth to third shift. When the vehicle speed drops to 32 km/h (20 mph) a three to one shift should occur.
- If transmission fails to upshift/downshift or if the torque converter clutch does not apply and release, refer to DIAGNOSIS BY SYMPTOM for concern diagnosis.
