This TFRE-PRO
Reprogramming Kit fits 1995 and newer Dodge and RAM vehicles equipped
with the 46RE, 47RE and 48RE automatic transmissions. Does not fit 1995-type valve bodies without the 3/16 checkball in lower channel casting.
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:
This Reprogramming Kit is designed for the aggressive sport driver
with engine power additions that is looking for that competitive edge in
transmission torque capacity. This kit includes valve body and servo
components as well as internal components that are calibrated for higher
operating pressures in all gears.
As a result, with a more aggressive pressure curve and MAX main line
set to 185 psi in all forward gears, the kit provides as much as 75%
increase in torque capacity for all the clutch elements including the
TCC clutch. This kit includes our patent-pending triple valve body
separator plate which allows you to achieve TCC operation in all forward
gears in 1st to 4th on 46-47 type valve RE bodies
with the use of a toggle switch (not furnished). Keeping the shift
timing at the OE RPM’s for the optimal engine power curve brings a whole
new driving experience to the truck. Therefore, the shifts are short,
clean and flat out hold as the power is rolled on. We feel this kit is
the Holy Grail of 47-48RE valve body kits on the market, you are going
love it!
Packed with patented components
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.
