Overdrive Range, Fourth Gear - Torque Converter Clutch Not Applied: Notes
WARNING: This page is about a different variant/trim than selected.
As the speed of the vehicle continues to increase, the powertrain control module (PCM) monitors the input signals from various engine and transmission sensors. The PCM uses this data to energize the 1-2, 3-4 shift solenoid (SS) valve in order to shift the transmission into fourth gear at the appropriate time.
