TransGo Reprogramming Kit


1996-2007 Dodge Cummins 5.9L 24V (46RE/47RE/48RE)

The TransGo TFRE-PRO Reprogramming Kit is engineered to give your 1996-2007 Dodge Ram Truck (With 46RE/47RE/48RE Transmission) a big increase in torque capacity. Specifically designed for the aggressive sport driver with plenty of engine power additions. This kit includes a valve body and servo components as well as internal components that are calibrated for higher operating pressures in all gears.

With a more aggressive pressure curve and MAX mainline set to 185 psi in all forward gears, this kit provides as much as 75% increase in torque capacity for all the clutch elements including the TCC clutch. TransGo’s patent-pending triple valve body separator plate is included, which allows you to achieve TCC operation in all forward gears in 1st to 4th (on 46-47 RE type valve bodies). Keeping the shift timing at the OE RPMs for the optimal engine power curve brings a whole new driving experience to the truck. The shifts are short and flat-out hold as the power is rolled on. This kit is the Holy Grail of 47-48RE valve body kits on the market!

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. 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 problems. Similarly, the new drop-in TV and throttle reducing valve (boost) with relocated lands restore 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.
