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 as an assembly. The A/T clutch pressure control solenoid valves A and B 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 shift valve
E, 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, 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.

STATOR SHAFT
The regulator valve maintains constant hydraulic pressure from the ATF pump to the hydraulic control system, while
also furnishing fluid to the lubricating system and torque converter. Fluid from the ATF pump flows through B and B’.
Fluid entering from B flows through the valve orifice to the A cavity. This pressure of the A cavity pushes the regulator
valve to the right side, and this movement of the regulator valve uncovers the fluid port to the torque converter and
the relief valve. The fluid flows out to the torque converter and the relief valve, and the regulator valve moves to the
left side. According to the level of the hydraulic pressure through B, the position of the regulator valve changes, and
the amount of fluid from B’ through torque converter changes. This operation is continued, maintaining the line
pressure.
NOTE: When used, ‘‘left’’ or ‘‘right’’ indicates direction on the illustration.
Increases in hydraulic pressure according to torque are performed by the regulator valve using stator torque reaction.
The stator shaft is splined with the stator in the torque converter, and its arm end contacts the regulator spring cap.
When the vehicle is accelerating or climbing (torque converter range), stator torque reaction acts on the stator shaft,
and the stator arm pushes the regulator spring cap in the direction of the arrow in proportion to the reaction. The
stator reaction spring compresses, and the regulator valve moves to increase the line pressure which is regulated by
the regulator valve. The line pressure reaches its maximum when the stator torque reaction reaches its maximum.
