BorgWarner 34068KIT 68RFE Friction Clutch Module Kit

The BorgWarner 34068KIT is the full friction content for a Chrysler 68RFE six-speed, the automatic bolted behind the 6.7L Cummins in 2007-2024 Ram 2500 and 3500 pickups. If your truck slips on the 3-4 shift while towing, flares between gears, smells burnt on the dipstick, or came in on a hook with a no-move complaint, the clutch packs are coming out anyway. This kit puts one brand of friction material in every drum instead of a mix of whatever was on the shelf, so the whole unit wears and applies the same way after the rebuild.

What the friction clutch module does in a 68RFE

The 68RFE has no bands. Every gear is made by applying two of its clutches at the same time and holding the planetary members in different combinations: underdrive, overdrive, reverse, 2C, 4C and the low/reverse clutch. The transmission computer fills each clutch through its own solenoid and watches pressure switches and speed sensors to confirm the clutch actually applied. That means the friction surfaces are the parts doing the real work, and they are also what the computer is grading on every shift. When a pack wears thin or glazes, the fill time stretches, the computer sees a ratio error, and the truck either shifts soft, flares, or drops into limp mode. The overdrive pack takes the most abuse because it carries torque from fourth through sixth gear behind a high-torque diesel.

What is in the box

BorgWarner lists the content by pack and by spline, because several 68RFE clutches use single-sided plates that alternate internal and external teeth instead of a conventional friction-and-steel stack:

• 2nd clutch (2C): 3 frictions
• 4th clutch (4C): 3 frictions
• Underdrive: 5 external and 5 internal
• Overdrive: 6 external and 6 internal
• Underdrive reverse: 2
• Low/reverse: 7 external and 7 internal

Symptoms that point to worn frictions

• Slip or engine flare on the 3-4 upshift, worst when loaded or towing
• Burnt-smelling or dark fluid with friction material in the pan
• Harsh or delayed shifts that do not clear after a fluid and filter service
• Delayed or no reverse, which points at the low/reverse or reverse pack
• Overdrive clutch or ratio codes setting after a hot pull, with the truck falling into second gear limp mode

How to confirm before you buy

Pull the pan first. A pile of black friction debris and fine metal confirms that clutches are gone and the unit needs a teardown. A clean pan with a shift complaint usually means the problem is electrical or hydraulic, not frictions. Our 68RFE 3-4 clutch failure guide walks through the overdrive clutch failure pattern, and the 68RFE valve body testing guide covers the solenoid switch valve wear that can partially apply the overdrive clutch and cook a brand new pack. Fix that root cause or this kit will fail the same way.

Fitment

This kit is listed for 2007-2024 68RFE units, which covers the Ram 2500 and 3500 with the 6.7L Cummins across those years. The 68RFE had running changes over that span, including a redesigned solenoid pack and connector for 2019. Count the plates you pull out of each drum as you disassemble and compare them with the list above before you start stacking. If you want us to double-check, send your year and VIN before ordering. Everything else we carry for this transmission is on the 68RFE parts page.

Install notes

• Soak every friction in clean ATF+4 for at least 30 minutes before assembly.
• Inspect each drum, piston and return spring. Replace the seals and bonded pistons at the same time; the 68RFE overhaul kit for 2019-2022 covers the gaskets and seals on later trucks.
• Set every pack to the clearance in your manual with a dial indicator. Too tight causes bind-up, too loose means long fill times and an overheated pack. The ATSG 68RFE rebuild manual has the clearance tables and selective snap ring data.
• Air-check each clutch circuit on the bench before the unit goes in.
• Flush or replace the cooler, fill with ATF+4 only, set the level with the fluid hot, and run the quick learn with a scan tool before the road test.

Does the 34068KIT fit my 2019 or newer Ram 2500 with the 6.7L Cummins?

It is listed for 2007-2024 68RFE units, so 2019-2024 trucks are in range. The later trucks changed the solenoid pack and connector, not the basic clutch layout, but count your plates on teardown and send us your VIN if you want fitment confirmed.

Does this kit include steels, seals or a filter?

No. It is the friction content for all clutch packs. Seals, gaskets, bonded pistons, steels for the conventional packs and the filter come in an overhaul or master rebuild kit, which most rebuilders buy alongside it.

Why does my 68RFE keep burning the overdrive clutch?

Industry write-ups point to thin frictions, housing flex that opens up clearance, and a worn solenoid switch valve bore that lets line pressure partially apply the overdrive clutch. Replace the frictions and also repair the valve body and consider an upgraded overdrive housing on a towing truck.

What fluid goes in after the rebuild?

Mopar ATF+4 only. Set the level with the transmission at normal operating temperature, because a cold check reads wrong on this unit.

Do I need a scan tool after installing new clutches?

Yes. The computer stores adaptive values from the old worn clutches. Run the quick learn procedure so it relearns fill times on the new frictions, then drive it gently while the adaptives settle.
