The Power Driven Diesel Full Manual Valve Body Build Kit (Shift Kit) allows you to modify your factory 47RH, 47RE, or 48RE valve body to provide manual shifting capability, as well as add the capability to lock up the torque converter in second, third, and fourth gear. The included instructions will walk you through the build process and help you build the valve body to your desired power level and shift firmness. Whether you’re building a 400 hp work truck or a 1,000 hp beast, this kit has you covered.

By installing the Power Driven Diesel Full Manual Valve Body Build Kit into your valve body, you can unlock the full potential of your transmission system, increasing line pressure to hold the power as well as allowing you to manually shift the transmission into whatever gear you choose instead of the gear the transmission thinks you should be in. It’s an ideal choice for diesel enthusiasts and individuals looking to maximize the power and capability of their vehicles.

Note: This kit converts your valve body into a full manual valve body. In factory form, if you put the shifter into D, the transmission will shift itself from first to second to third gear all by itself. A full manual valve body disables that. Putting the shifter into manual first will be first gear, putting the shifter into second will shift to second gear, and shifting the transmission to D will now be third gear, all regardless of throttle or mph.
