How Much Does a 68RFE Rebuild Cost? Parts Breakdown
The 68RFE is the six-speed automatic behind the 6.7L Cummins in 2007.5 and newer Ram 2500 and 3500 trucks, the double-overdrive replacement for the old 48RE. When it is time to rebuild one, the honest answer to "how much does it cost" is: it depends almost entirely on which parts you put back in. Labor is fairly fixed; the parts side is where a rebuild swings from a stock refresh to a built unit that survives a tuned, towing Cummins. This breakdown walks through the parts by category, what actually lasts, and how to think about the effort so you can budget the job without getting surprised.
Note up front: we do not quote competitor prices here. What follows is a parts-and-labor framework so you know where the money goes and which upgrades earn their keep.
What a 68RFE rebuild has to cover
The 68RFE is a band-less, clutch-to-clutch design with dual filters and a dual-face torque converter lockup clutch that can lock in gears 2 through 6. That means every gear change lives and dies on the friction clutches and the pressure that applies them. A proper rebuild is not just "new frictions and seals," it is restoring clutch capacity, sealing the hydraulics, and making sure the converter and pump are not feeding debris back in. Skip any one of those and you are rebuilding it again.
Parts breakdown by category
1. Frictions and steels (the core of the job)
This is the heart of any rebuild kit. Fresh frictions and steels restore clutch capacity in every pack. On the 68RFE, the overdrive and 2C clutch packs are the packs builders focus on first, which is why performance kits add billet pistons and thicker clutch-and-steel stacks in those positions to add apply area and heat mass. A basic kit gives you OE-style frictions; a master or performance kit steps up the friction material and steel count so the packs shrug off tow heat instead of glazing.
2. Gaskets, seals, o-rings and bushings
The rubber-and-paper side is cheap in dollars but non-negotiable. A complete gasket and sealing kit plus a full bushing kit is what keeps line pressure where the TCM commands it. Worn bushings and hardened seals bleed pressure and are a common reason a "rebuilt" trans still shifts soft. Every quality kit, from a basic 3-piece to a master kit, includes these because they are the difference between a leak-free unit and a comeback.
3. Filters and fluid
The 68RFE uses two filters - a spin-on and a sump/pan filter - and calls for ATF+4. Both filters go in on every rebuild; reusing either one is how debris from the old failure gets pumped straight into fresh clutches. Budget the correct fluid volume for a double-overdrive six-speed plus converter fill, and always refill to spec rather than by eye.
4. Valve body and shift correction
Pressure control is the other half of clutch life. A tired valve body or worn separator plate lets apply pressure sag, which cooks the very clutches you just installed. Options run from a shift-kit correction inside the stock valve body up to a remanufactured heavy-duty valve body. On tuned trucks, a higher-line-pressure valve body strategy is a common upgrade because it firms up the clutch apply and reduces slip.
5. Torque converter
The converter is where a lot of 68RFE rebuilds are won or lost. A worn or shuddering converter sends debris through the whole hydraulic system and starves the pump. A multi-disc lockup converter built for Cummins torque is the upgrade that pays back in both durability and drivability, especially on a truck that tows or is tuned.
6. Billet hard parts (for tuned and towing trucks)
This is the optional tier. Billet input shafts, billet 2C and overdrive pistons, and upgraded snap-ring retainers add strength where added power finds the weak link. A stock-power truck may not need them; a tuned Cummins that has already broken parts absolutely does. This is the category that separates a stock-spec rebuild from a "built" transmission.
Which kit level fits you
Match the kit to how the truck is driven:
- Basic (frictions, steels, gaskets, seals, filter) - a stock daily driver getting a clean refresh. See the 68RFE rebuild kits range for tiers.
- Advanced (adds shift kit and servo) - a truck that tows occasionally and you want firmer, cooler shifts.
- Master 7-piece (adds solenoids and bushings) - the do-it-once choice for a high-mile or tuned truck, since it covers the electrical and pressure-control wear items at the same time.

Replace while you are in there
Since the case is open, do not leave obvious wear items for a second teardown:
- Both filters (spin-on and sump) - always.
- Torque converter, if there is any shudder, debris, or high miles.
- Thrust washers and bearings, plus the bushing kit.
- External cooler flush or replacement, so old debris does not contaminate the fresh build.
- Fresh ATF+4 to the correct capacity, and clear the adaptive tables after the job.
Cost and effort framing
Think of the cost in three buckets. Labor is the most predictable: pulling, tearing down, rebuilding, and reinstalling a 68RFE is a full professional job measured in many hours, and it is an advanced DIY project that needs a lift, a clean bench, and the ability to set clutch clearances. Core parts - the rebuild kit and both filters - are the fixed middle. Upgrades - converter, valve body strategy, and billet hard parts - are the variable that moves the total the most. The single best way to control cost is to right-size the kit to your truck: a stock daily does not need billet, and a tuned tow rig that skips the converter and pressure upgrades will simply be back on the bench.
Frequently Asked Questions
What fails first on a 68RFE?
The clutch packs and pressure control are the usual culprits, with the overdrive and 2C packs getting the most attention in performance rebuilds. That is why builders add billet pistons and thicker clutch-and-steel stacks in those positions and pair them with a higher-pressure valve body strategy.
Do I need to replace the torque converter during a 68RFE rebuild?
If there is any shudder, contamination, or high mileage, yes. A failing converter sends debris through the hydraulics and starves the pump, which will take out a fresh rebuild. A multi-disc converter built for Cummins torque is a common and worthwhile upgrade.
What fluid and filters does a 68RFE use?
The 68RFE calls for ATF+4 and uses two filters - a spin-on and a sump/pan filter. Both filters are replaced on every rebuild so old debris is not pumped into the new clutches.
