Shift Patterns: Upshifts
WARNING: This page is about a different car, the 2003 Ford Econoline. However, it is still accessible from the selected car via links, so may be relevant.
Transmission upshifting is controlled by the powertrain control module (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.
