Shop with Blessed Performance for the Tier One Transmission 750HP Stage 2 68RFE Transmissions for your 2019-2024 Dodge Ram 2500/3500 6.7L Cummins diesel. The Tier One Stage 2 Transmissions are built with care with technicians that have decades of combined experience in the performance transmission market. Each Stage 2 68RFE starts its life as factory 68RFE core that's fully disassembled, cleaned, and thoroughly inspected for damage before being repurposed for a Stage 2 68RFE transmission build. We include a SunCoast billet triple-disc torque converter that's resistant to warp and whose three discs provide a ton of surface area for holding power and load. Replacing the stock input shaft is a Sonnax billet input shaft made out of 300M steel that can handle and hold huge power in extremely aggressive applications. The Stage 2 68RFE transmission comes standard with a billet steel input clutch drum that solidly holds the clutch packs in place and resists warping and shifting even under extreme levels of power and torque. Tier One includes a billet 4C spring retainer that helps prevent gear walkout and premature failures at elevated levels of power. The Stage 2 comes with a billet steel 4C piston that handles the strain of extra horsepower better than stock. The heart of the Stage 2 68RFE is its Tier One Billet High Pressure Valve Body that features a billet aluminum construction that resists flex under load and utilizes deep worm tracks for increased fluid flow and cooling. The valve body also features a bonded separator plate that better seals the worm tracks and prevents cross-leaks. Each transmission comes with a deep transmission pan that holds more fluid than stock to improve cooling. The Stage 2 transmission is also fitted with a high-performance rebuild kit that includes new wearable parts with 14 overdrive clutches, 4 2nd gear clutches, and 4 4th gear clutches. Tier One throws in a new OEM solenoid pack and OEM line sensor to ensure proper operation. Each Stage 2 68RFE transmission is topped off with new seals and gaskets before being air-checked for leaks. Tier one goes over every miliimeter of their transmissions internal components to guarantee excellent function and reliability. All parts are disassembled and cleaned from our OEM cores to ensure your new 68RFE transmission is free from contaminants and other debris. We carefully inspect your transmission's planetary gear train for damage before fully speccing all bearings and washers for endplay. The original transmission pump is flat-sanded, checked for proper clearances, and vacuum-tested. The valve body is likewise flat-sanded and its solenoids thoroughly inspected for better than OEM function, and we replace the OEM accumulator plate to avoid potential codes and issues down the road. Each transmission is also fitted with a TIG-welded planetary pinions. The performance rebuild kit includes new Borg Warner clutches, seals, gaskets, and sealing rings to replace all the wearable parts of the transmission before it's installed on your Ram 2500 or Ram 3500.
