This TFOD-Diesel
Shift Kit fits 1988 to 2003 Dodge, Ram and Jeep vehicles equipped with
the A518, 46RH, 46RE, A618, 47RH and 47RE TorqueFlite four speed
automatic transmission 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 Shift Kit includes valve body and internal components
that are designed for higher operating pressures. As a result, with MAX
main line pressure set to 125 psi in 1st, 2nd and 3rd gear and up to 150 psi in 4th
or in lock-up, this kit provides a significant increase in torque
capacity for all of the friction elements including the TCC clutch.
These elevated pressure specs are ideal for the heavy-duty work truck as
well as for pulling the fishing boat to the loading ramp. With the kit
installed it brings a whole new driving experience to the truck while
keeping the shift timing at the OE RPM’s for the optimal engine power
curve. Therefore, the shifts are short and clean with no harshness,
bangs or clangs.
There are several innovative components in this kit. For instance,
our line-to-converter feed system which helps the unit run cooler and
promotes longer TCC clutch life. Also included is a TransGo pioneered
manual valve to reduce overnight forward and reverse delayed engagement
complaints due to torque converter drain back.
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.
