Hydraulic Control

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