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, shift valves A, B, D, E, 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 shift valve C, 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 the 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.
