2003-2007 Cummins 5.9L 48RE Transgo Valve Body Repair Kit (SK-48RE)

The TransGo kit includes valve body and internal components that are designed for higher operating pressures. As a result, with MAX main line pressure set to 115 psi in 1st, 2nd and 3rd gear and up to 160 psi in 4th or in lock-up, this kit provides a significant increase in torque capacity for all of the friction elements including the TCC clutch. These elevated pressure specs are ideal for the heavy-duty work truck as well as for pulling the fishing boat to the loading ramp. With the kit installed it brings a whole new driving experience to the truck while keeping the shift timing at the OE RPM’s for the optimal engine power curve. Therefore, the shifts are short and clean with no harshness, bang’s or clangs.

There are several innovative components in this kit. For instance, our line-to-converter feed system which helps the unit run cooler and promotes longer TCC clutch life.  Also included is a TransGo pioneered manual valve to reduce overnight forward and reverse delayed engagement complaints due to torque converter drain back.

Lastly, this kit can be installed with the transmission in the truck. On the other hand, there are internal sealing rings furnished in the kit if the transmission is on the bench for overhaul.
