TransGo 48RE-HD2 Reprogramming Kit

Fitment

2003-2007 Dodge Cummins 5.9L 54V (48RE)

The 48RE-HD2 Reprogramming Kit is designed for hard-working 2003-2007 Dodge Ram 2500/3500 (48RE Transmission) that tow and haul heavy loads. Common complaints on the 48RE transmission are TCC slip or shudder, direct clutch failure, as well as torque converter drain back. With a max mainline pressure set to 145 psi in 1st through 3rd gear and up to 180 psi in 4th gear or lock-up as well as a more aggressive pressure curve, this kit includes valve body, servo components, and internal components calibrated for higher operating pressures in all gears to provide a significant increase in torque capacity for all the clutch elements (including the TCC clutch).

There are several innovative components in this kit. One of them is the line-to-converter feed system which helps the unit run cooler and promotes longer TCC clutch life. The TransGo pioneered manual valve reduces overnight forward and reverse delayed engagement complaints due to torque converter drain back. The kit also includes a drop-in detent ball bore repair bullet that works directly in the existing worn bore and helps with the park dis-engagement problem. The new drop-in TV and throttle reducing valve (boost) with relocated lands restore the TV pressure boost system functionality providing better line pressure response in forward and reverse ranges. In addition, the valve body modifications provide increased flow to the direct clutch and band release circuit reducing 2-3 shift overlap. Best of all, you can install this kit with the transmission in the truck.
