Shift Control
The PCM instantaneously determines which gear should be selected by various signals sent from sensors, and actuates the shift control solenoid valves A and B to control shifting. Also, a Grade Logic Control System has been adopted to control shifting in [D4 ] position while the vehicle is ascending or descending a slope, or reducing speed.
