Build a stronger, cooler, smoother drivetrain for your 2019–2024 Ram Heavy Duty. CPP Diesel stocks proven upgrades and OE-quality service parts for 68RFE and Aisin AS69RC applications—torque converters, valve bodies, clutch/rebuild kits, pans/filters, coolers & lines, sensors, flexplates, mounts, and hardware curated to fit your 6.7L Cummins.
Check your build sheet/VIN and the tag on the transmission. 2500 models commonly use 68RFE; many 3500 HO trucks use the Aisin. Match parts by the exact code on your tag.
A relearn/teach-in procedure is recommended after major hardware changes. Follow the product and service manual steps so shift quality adapts correctly.
Yes—added fluid and increased surface area improve heat capacity. Pairing a deep pan with an upgraded cooler/lines offers the best temperature control under heavy load.
High torque, aggressive launches, or competition use can exceed OE margins. Billet shafts and SFI flexplates add safety and reliability for big power or racing classes that require them.
Use the fluid type and procedure specified for your transmission and the products you install. Check level with the vehicle on level ground and at the temperature indicated in your service manual.
