68RFE Shift Kit 2019, new and ready to install. Fits the 68RFE. Ships fast from the USA.
This is the TransGo RFE-HP-19UP High Pressure Tuneless Reprogramming Kit for the 2019 and newer 68RFE, the six-speed behind the 6.7L Cummins in the Ram 2500 and 3500. TransGo built it for the two complaints that keep coming back on these trucks: repeat underdrive clutch failure after engine tuning and overdrive clutch failure once the truck is making more power or pulling heavy. It is the step above the basic SK 68RFE-19UP shift kit, and its main features go in with a pan and valve body drop, with no transmission removal and no transmission tuning required.
The 68RFE applies its clutches with solenoid-controlled pressure, and the computer sets line pressure. Once an engine is tuned or a truck is working hard, stock pressure can let the underdrive and overdrive clutches slip long enough to overheat. TransGo states this kit adds 36 percent more line pressure at all throttle openings without computer software. It does that hydraulically with five dual-sealing billet accumulator pistons on recalibrated springs, a heavy-duty accumulator plate and a laminated triple separator plate with gaskets. The box also includes a torque converter limit system, a triple-disc converter calibration valve and a heavy-duty underdrive snap ring. TransGo lists those last items as optional work done with the transmission out, where they address rough lock-up with triple-disc converters, converter drain-back and a worn TC limit bore in the pump cover.
Start with software and recall status. FCA released powertrain control module updates for 2019 Ram 2500 and 3500 Cummins trucks covering harsh downshift clunk during exhaust brake use and upshift quality, and Safety Recall W03 covers roughly 85,000 2019-2020 Ram 2500 and 3500 trucks with the 68RFE. Make sure both are done. Then check the fluid and look for clutch ratio codes. Our guide on 68RFE harsh shift causes walks through software, adaptives and hardware in order, and 68RFE shift solenoid symptoms covers the pressure switch and solenoid codes that point to the valve body instead of the clutches. If the clutches are already burnt, this kit protects a rebuild; it does not restore worn frictions.
This kit is for 2019 and newer 68RFE transmissions in Ram 2500, 3500 and cab-chassis trucks with the 6.7L Cummins. Do not fit it to a 2007-2018 unit. Sonnax documents that the 2019-up 68RFE went to a blue connector solenoid pack and that the low/reverse solenoid no longer controls the converter clutch, with the reverse clutch on its own solenoid, so the valve body hydraulics differ from the earlier trucks. Compare with the lighter TransGo SK 68RFE-19UP shift kit or browse every 68RFE part on our 68RFE parts page. If you are unsure which transmission your truck has, send us the year and VIN.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No, not for the main features. TransGo states the performance and underdrive protection parts install with a pan and valve body drop. Only the optional converter limit and triple-disc converter features need the transmission removed.
No. It is a Tuneless kit: the added line pressure comes from hydraulic changes in the valve body, not from computer software.
No. It is for 2019-on 68RFE units only. The 2007-2018 trucks use a different valve body layout and different TransGo kits.
The SK 68RFE-19UP is TransGo's valve body repair kit for the 2019-up unit. The RFE-HP-19UP adds high pressure calibration and underdrive and overdrive clutch protection for tuned, fleet or hard-working trucks.
ATF+4. Replace the filter at the same time and check the level hot with the engine running.
Not by itself if the cause is solenoid switch valve bore wear. TransGo recommends a separate switch valve kit for that wear, installed while the valve body is out.
