Shift Control
The PCM instantly determines which gear should be selected by various signals sent from sensors and switches, and it actuates the shift solenoid valves A, B, C, and D to control gear selection.
The shift control on the seven-position transmission includes the automatic shift control in D (1st through 5th gears) and D3 (1st through 3rd gears), the grade logic control, and the shift-hold control.
The shift control on the five-position transmission includes the automatic shift control in D (1st through 5th gears) and S (1st through 4th gears), manual shift mode control in D (D-paddle shift mode) and S (sequential sportshift mode), the grade logic control, and the shift-hold control.
