BD Diesel 19-24 Dodge 68RFE 4WD TorqueMaster Transmission w/ Billet Input Shaft
If your 2019-2024 four-wheel-drive Ram 2500 or 3500 with the 6.7L Cummins has burned up its overdrive clutches, slips under a trailer, or is about to get more power from a tune, this is the complete transmission built to stay together. The BD Diesel TorqueMaster, part number 1064294B, is a new, fully assembled 68RFE with a billet input shaft, sold as BD's Stage 5 unit.
The stock 68RFE gives up first in the overdrive clutch pack. Sonnax describes the factory OD clutches as single-sided with a steel core only .034 inch thick, which is why they warp and burn when heat builds under load. BD attacks that directly. According to BD, the overdrive and 2C clutch packs each get a 33 percent increase in clutch count, made possible by billet QT100 pressure plates that also cut deflection and distortion inside the drum. A longer Big Stack overdrive shaft carries the larger pack, and a steel girdle on the 2C piston broadens its apply area.
The billet input shaft is the headline. It is there to take the shock of hard throttle and high horsepower, which is how stock input shafts break on modified trucks. BD also lists a heavy-duty cam and roller low/reverse one-way clutch, a new billet 4C spring retainer, a reinforced accumulator plate, and a bonded-gasket valve body separator plate that raises line pressure while stopping internal cross leaks. Every unit ships with a hard anodized valve body and a new solenoid pack installed, plus a BD deep sump pan for extra fluid capacity and less case flex.
Make sure the problem is the transmission and not a cooling or electrical issue that will kill the new unit too. GEARS Magazine puts the ideal maximum fluid temperature on these trucks at 200 degrees F and notes that life roughly halves for every 20 degrees above it, so confirm cooler flow is healthy. Our 68RFE Ram 2500 Cummins common problems guide covers the failure patterns, and 68RFE towing upgrades explains when a built unit makes more sense than a stock rebuild.
This listing is the four-wheel-drive version for 2019 through 2024 Dodge and Ram trucks with the 68RFE and 6.7L Cummins. A two-wheel-drive truck needs the matching 2WD unit, and earlier 2007.5-2018 trucks use a different BD part because the 68RFE changed in 2019. Transmission Digest documents that the 2019 redesign added a separate torque converter clutch solenoid and a reverse solenoid with a blue connector, so 2019-up and earlier units do not swap. Check your driveline and model year, or send us your VIN and we will confirm. More parts for this transmission are on our 68RFE collection page.
This is a heavy, freight-shipped assembly of roughly 240 pounds, so plan for a lift or a transmission jack rated for it. The torque converter is not included. BD states that special tuning is required on 2019-up applications for increased line pressure and that a line pressure controller is not included, so budget for that before the truck goes back on the road. Flush or replace the cooler and lines; debris from the failed unit will go straight into the new one. A new 68RFE transmission cooler for 2019-2024 is cheap insurance. Fill with ATF+4, check level hot, and keep a 68RFE service kit with ATF+4 and filters on hand for the first service. BD notes that race abuse is not covered under its warranty.

Doing this repair right usually means replacing these at the same time. Same transmission, ships together.
No. This part number is the transmission only. Reuse a healthy converter that matches your truck or buy a converter separately, and never reuse one from a unit that came apart with debris in it.
Yes. BD states that special tuning is required on 2019 and newer applications to raise line pressure, and that the line pressure controller is not included in this package.
No. This is the 4WD unit for 2019-2024. Two-wheel-drive trucks need the 2WD version, and 2007.5-2018 trucks use the earlier 68RFE design with a different connector and solenoid layout.
ATF+4, the factory specification for the 68RFE. Set the level with the fluid hot. The included deep pan holds more fluid than stock, so expect to add more than a factory fill.
It replaces the factory input shaft with a stronger billet piece built to take the shock of hard throttle and high torque, which is a known breaking point on modified 6.7L trucks.
Flush or replace the transmission cooler and lines, use fresh ATF+4, and confirm the torque converter is in good shape. A failed unit leaves debris in the cooler that will contaminate a new transmission.
