Shift Control
The PCM controls the shift pulley ratio through the solenoids, while receiving input signals from the various sensors and switches located throughout the vehicle. The PCM actuates the pulley control solenoids to control pulley control valves A and B. Drive pulley pressure is regulated at pulley control valve B and applied to the drive pulley, driven pulley pressure is regulated at pulley control valve A and applied to the driven pulley, and the pulley ratio is changed to their directed ratio.
