VALVE B
The valve body includes the main valve body, the regulator valve body, the servo body and the accumulator body. The
ATF pump is driven by splines on the left end of the torque converter which is attached to the engine. Fluid flows
through the regulator valve to maintain specified pressure through the main valve body to the manual valve, directing
pressure to each of the clutches. The shift solenoid valves B and C are mounted on the outside of the torque converter
housing. The shift solenoid valve A and the torque converter clutch solenoid valve are mounted on the torque
converter housing. The A/T clutch pressure control solenoid valves A, B, and C are mounted on the transmission
housing.

The main valve body contains the manual valve, the modulator valve, the shift valve C, the shift valve D, the servo
control valve, the cooler check valve, the torque converter check valve, the reverse CPC valve, the lock-up shift valve,
the relief valve, the kick-down valve, the kick-down short valve, and the ATF pump gears. The primary function of the
main valve body is to switch fluid pressure on and off and to control hydraulic pressure going to the hydraulic control
system.
The regulator valve body is located on the main valve body. The regulator valve body contains the regulator valve, the
lock-up timing valve, and the lock-up control valve.
