Shift Control
The PCM instantly determines which gears should be selected by various signals sent from sensors and
switches, and it actuates shift solenoid valves A, B, C, D, and E to control shifting transmission gears.
Also, a grade logic control system has been adopted to control shifting in the D position. The PCM compares
actual driving conditions with memorized driving conditions, based on the input from the accelerator pedal
position sensor, the engine coolant temperature sensor, the barometric pressure sensor, the brake pedal position
switch signal, and the shift lever position signal, to control shifting while the vehicle is ascending or descending
a slope.
