HYDRAULIC CONTROLS 

Valve Bodies 

The valve body includes the main valve body, the regulator valve body, and the servo 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 the shift valves and to each of the clutches via the solenoid valves. The shift solenoid valves A, B, 
C, D, and E are bolted on the servo body. The A/T clutch pressure control solenoid valves A, B, and C are 
mounted on the outside of the transmission housing.

Main Valve Body 

The main valve body contains the manual valve, the shift valves A, B, C, and E, the relief valve, the lock-up 
control valve, the cooler check valve, the servo control 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.
