TransGo A/T Valve Body - 48REHD2

Specifically engineered for hard working trucks that tow or haul heavy loads, the 48RE-HD2 Reprogramming Kit fits 2003 to 2008 Dodge and Ram vehicles with the 48RE automatic transmission with gas or diesel engine. This kit will not work with hybrid or converted 47RE valve bodies. Common complaints on this transmission are TCC slip or shudder, second gear band and direct clutch failure as well as torque converter drain-back. With max main line pressure set to 145 psi in first through third gear and up to 180 psi in fourth gear or lock-up as well as a more aggressive pressure curve, this kit includes valve body and servo components as well as internal components calibrated for higher operating pressures in all gears to provide a very 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 our line-to-converter feed system which helps the unit run cooler and promotes longer TCC clutch life. Likewise, 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, this helps with difficult park dis-engagement problem. Similarly, the new drop-in TV and throttle reducing valve (boost) with relocated lands restores the TV pressure boost system functionality providing quick 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. Lastly, you can install this kit 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.
