Turbo 400 Pressure Regulator Assembly

This valve will regulate the torque converter pressure. Lower converter pressure reduces the chance of having thrust main bearing issues in the engine.
The kit includes a billet aluminum governor cover, 12″ premade hose, misc fittings and regulator valve.
This is the new design valve with three pressure ports for monitoring torque converter charge pressure.

The ATI TH-400 case doesn’t have the factory governor boss therefore this kit will not work. The case will have to be tapped for a fitting just like the Powerglide does. So we recommend using the Powerglide kit instead (Part#:330601).
