Valve body to case torque 98 inch lbs. Valve Body Pro: The leader in remanufactured valve bodies All valve bodies are run through a series of shift cycles at operating temperature, then precisely calibrated using state-of-the-art valve body test equipment to verify proper operation of the pressure/control circuits. Forward pattern full manual valve body with transbrake gives the driver complete control of gear range selection. No ECM required. Deep pan not required. Redesigned oil circuitry provides super positive gear changes, increased torque capacity and instant transmission brake release for the ultimate in efficiency, performance, and durability. The 4L80E uses shift solenoids A and B to control upshifts and downshifts in all forward ranges. The solenoids are both powered with system voltage when the ignition is on. Ground is provided by the vehicle PCM in a specific sequence to control shift scheduling (figure 1). Easily Convert the 4L80E to Full Manual Control They say necessity is.
