This TFOD-HD2
Reprogramming Kit fits 1988 to 2003 Dodge, Ram and Jeep vehicles with
both small case transmissions such as the A500, 40RH, 42RH, 40RE, 42RE,
44RE as well as big case transmission such as the A518, 46RH, 46RE,
A618, 47RH and 47RE with gas or diesel engines. This kit does not fit the 48RE transmission or the 2003 Dodge trucks with the 8th VIN code of ‘C’. 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 TransGo Reprogramming Kit is designed for the aggressive sport
driver and off-road enthusiast. This kit includes valve body and servo
components as well as internal components calibrated for higher
operating pressures in all gears. Designed to deliver a more aggressive
and adjustable pressure curve with a range from MAX 122-137 PSI in 1st,
2nd and 3rd gear and up to 145-160 PSI in 4th or in lock-up, the kit
provides a significant increase in torque capacity for all the clutch
elements including the TCC clutch. Keeping the shift timing at the OE
RPMs for optimal engine power curve brings a whole new driving
experience to the truck. As a result, the shifts are short, clean and
flat out hold as the power is rolled on, you are going love it!
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 has an
optional “Gear Command” feature that holds 1st, 2nd
and 3rd gear to any engine speed. When the gear command feature is
installed, this will allow the transmission to be manually down shifted
to 1st gear at any speed. This feature is very popular for off road and rock crawling enthusiasts.
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.
*The gear command feature is NOT advised for diesel engines.
Also, the PSI output applies to big case units only and will vary
depending on oil pump volume output.
