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, 2nd gear band and direct clutch failure as well as torque converter drain-back.
Features and benefits:
With max main line 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 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.
