Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Hydraulic Control
The lower valve body assembly includes the main valve body, the secondary valve body, the CVT driven pulley pressure control solenoid valve, the CVT drive pulley pressure control solenoid valve, the CVT clutch pressure control solenoid valve, and the inhibitor solenoid valve. These valve bodies are positioned on the lower portion of the transmission housing. The manual valve body is bolted on the intermediate housing.
The main valve body contains the start clutch shift valve, the shift inhibitor valve, the lubrication regulator valve, and cooler relief valve. The secondary valve body contains the pressure high (PH) regulator valve, the pressure high control (PHC) shift valve, the start clutch back-up valve, the clutch reducing valve, and the start clutch accumulator valve. The CVT driven pulley pressure control valve contains pulley control valve A and the driven pulley control valve with the solenoid. The CVT drive pulley pressure control valve contains pulley control valve B and the drive pulley control valve with the solenoid. The CVT start clutch pressure control valve consists of the start clutch pressure control valve and the solenoid. These solenoids are controlled by the PCM. The manual valve body contains the manual valve and the reverse inhibitor valve.
The CVTF pump is located on the transmission housing, and it is linked with the input shaft by the sprockets and the sprocket chain. The pulleys, the forward clutch, and the start clutch receive fluid from their respective feed pipes, and the reverse brake receives fluid from an internal hydraulic circuit.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
