Shift Patterns: Upshifts

WARNING: This page is about a different car, the 2004 Ford Econoline, 2004 Ford E450 Super Duty, and 2004 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: This vehicle has adaptive shift strategies. Whenever the battery has been disconnected and reconnected, some abnormal drive symptoms will occur while the vehicle relearns its adaptive strategy. The customer needs to be notified that they may experience slightly different upshifts (either soft or firm) and that this is a temporary condition that will eventually return to normal operating condition.

Transmission upshifting is controlled by the PCM. The PCM receives inputs from various engine or vehicle sensors and driver demands to control shift scheduling, shift feel and torque converter clutch (TCC) operation.
