Electro/Hydraulic Valve Body

Electro/Hydraulic Valve Body:







Located in the oil sump, the valve body is the electro/hydraulic control center for regulating and distributing pressurized transmission fluid for activating the various clutches, torque converter variable lock up, and regulation of main line oil pressures.

Sub components of the valve body assembly include:
- Manual valve
- One main pressure regulator solenoid (Pressure Regulator Force Motor Solenoid - "GM term")
- One torque converter regulator solenoid (also serves the Reverse Lock out function)
- Three MV shift solenoids (When activated in a coded sequence provide shifts for 1-2, 2-3, 3-4, 4-5)
- The spool valves and springs for controlling apply pressures, activating shifts, regulating torque converter lock up, etc.
- Four accumulator chambers for "cushioning" the transmission fluid apply pressure during upshifts 1-2, 2-3, 3-4, 4-5.
