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 valve bodies include the main valve body, the secondary valve body, the regulator valve body, and the accumulator body. They are bolted to the torque converter housing. The main valve body contains the manual valve, the modulator valve, the torque converter check valve, the shift valves A, B, D, E, the CPC valve C, the cooler check valve, the relief valve, the lock up shift valve, the lock up timing valve, the lubrication control valve, the lubrication check valve, and the ATF pump gears. The secondary valve body contains the shift valve C, the CPC valve A, B, the reverse CPC valve, the servo control valve, and the kick down valve. The regulator valve body contains the regulator valve, the lock up control valve, and the 3rd accumulator. The accumulator body contains the 1st, 1st-hold, 2nd, 4th, and 5th accumulators, shift solenoid valves A, B, C, and torque converter clutch solenoid valve. Fluid from the regulator passes through the manual valve to the various control valves. The all clutches receive fluid from the internal hydraulic circuit.
