Drive Range, First Gear (Hydraulic Circuits): Notes
WARNING: This page is about a different variant/trim than selected.
As the vehicle speed increases, the transmission control module (TCM) receives input signals from the automatic transmission input and output speed sensors, throttle position sensor and other vehicle sensors to determine the precise moment to energize or turn on. Shift solenoid valve E is commanded ON. Shift solenoid valve D is already on and commanded for low pressure.
