Shift Control Mechanism

To shift gears, the PCM controls shift solenoid valves A, B, and C, and automatic transaxle (A/T) clutch pressure control solenoid valves A and B, while receiving input signals from various sensors and switches located throughout the vehicle. The shift solenoid valves shift the positions of the shift valves to switch the port to send hydraulic pressure to the clutches. The A/T clutch pressure control solenoid valves A and B control the CPC valve A and B to shift smoothly between lower gear and higher gear. This pressurize a line to one of the clutches, engaging the clutch and its corresponding gear.
