    This RFE-HP-19UP High Pressure Tuneless™ Reprogramming Kit  is a must-have for stock, fleet, hard-working, or enhanced powered 2019-on Ram trucks with a 68RFE.  It includes essential fixes and major durability upgrades for the top complaints of repeat underdrive and overdrive clutch failure. Transmission removal not required. No transmission tuning required.

    Features without removing the transmission:
    • Stops repeat underdrive clutch failure after tuning
    • Adds 36% more line pressure at all throttle openings without the need of computer software
    • Reduces OD clutch failure with added power
    • Major performance and durability upgrades
    • Perfect for performance and hard-working trucks
    • Short, clean shifts that really hold the power
    • Calibration that relearns quickly
    Optional features by removing the transmission:
    • Stops rough lockup when using triple disc converters
    • Prevents converter drain back
    • Allows use of pump cover with worn TC limit bore
    • 5 dual-sealing billet accumulator pistons with recalibrated springs
    • Torque converter limit system
    • Heavy duty accumulator plate
    • Triple-disc converter calibration valve
    • Heavy duty underdrive snap ring
    • Laminated triple separator plate with gaskets
    Note: High mileage vehicles sometimes come in with codes P0841, P0871, P0988, P1775 and P1776 due to wear at the solenoid switch valve bore in the valve body. If you need to address solenoid switch valve bore wear, then also check out our solenoid switch valve kits.
    Optional Upgrade: 

    The TransGo hot-forged 1045 steel fully CNC machined overdrive pressure plate #RFE-PP-ODHP allows you to quickly and easily add extra capacity to the overdrive clutch pack in all models. Also, this pressure plate is a direct fit for the OEM drum. Consequently, there is no need for you to spend a small fortune on an aftermarket drum. When using this pressure plate, you can add two overdrive frictions for single sided application and one overdrive friction for double sided application. For single sided friction setup like in the 68RFE, the new stack up yields a 15% increase in surface area. Alternatively, for double sided friction setup like in the 545RFE, the end result is a 25% increase in surface area.
