SunCoast 68RFE Catagory 2 500HP Transmission With Converter 07.5-18 Ram 6.7L Cummins

If you're looking for reliability out of a mild performance transmission for the 2007.5-2018 Ram 6.7L Cummins, SunCoast offers an effective solution to bolster your drivetrain with their Category 2 500HP capable transmission. With an approach centered in science and study, SunCoast's Category 2 Transmissions have been built with heavy towing and street driving in mind. Give yourself a little room for an increase in performance and reach for the sun.

The SunCoast Category 68RFE transmissions are designed and developed with the intention of taking a systematic approach to solving the issues with the 68RFE transmission.  SunCoast approachs each deficiency and need from a scientific approach. They aim to offer the most complete series of 68RFE transmissions available on the market today.

The SunCoast V2 68RFE Billet Drum is the most revolutionary thing that has happened for the 68RFE. SunCoast have touted that no other project they've worked on has had as much research and development invested. This drum has many features that have been improved over previous iterations as well. There is a 24% improvement in hydraulic clamping force over the factory drum and increased friction elements in overdrive, and all centrifugal supply springs were removed. SunCoast's V2 billet drum was redesigned with a new lip seal style for the outer seal by increasing the diameter of the outer sealing surface. The quad-ring design of the inner drum o-ring maintains compression during high RPMs and has consistent factory-like CVIs. The drum’s wall thickness was also increased to improve drum rigidity and to reduce lateral movement in the overdrive supply plate. This V2 billet drum is a completely assembled drop-in replacement for 68RFE vehicles. In the Category 2 Transmission however, it's already installed and ready to get to work.

The factory molded piston is prone to unevenly engage which leads to excessive heat in the clutches and steels causing burning and premature failure. In SunCoasts 68RFE transmission rebuild kit, they replace the factory piston with an improved billet piece that also allows space for an additional clutch further increasing surface application area. The new Category Series 68RFE transmissions are designed with the builder in mind, with options available for mild to extreme duty uses.

SunCoast is proudly equipping their Pro-Loc Ducenti 200psi Shift Calibration Kit in the 68RFE. SunCoast has spent many years refining a valve body solution. In this valve body, SunCoast addresses several key issues within this hydraulic circuit using a multi-faceted approach through research and refinement. This kit includes everything you will need to achieve 200psi without any additional tuning and is designed to be a complete drop-in unit. Features and benefits of this shift calibration kit include a new pump half, TCC limit valve, TCC switch valve, five billet three-ring accumulator pistons, billet upgraded valve body plate, an upgraded heavy duty accumulator plate, and custom-calibrated spring rates for PR circuit. Giving you the best possible shifting performance.

Every new Suncoast transmission receives a new OEM solenoid back from Mopar.

The factory 68RFE has had several issues with the pressure relief check valve system in the transmission pan filters. Initially, the 68RFE had issues with the plastic filter splitting in half. This was later remedied with a pressure relief valve on top of the filter. This later showed to also lead to failures as the valve would release itself from the filter all together. SunCoasts bottom feeder filter kit allows the usage of a torqueflite filter, and this conversion will not only prevent pump cavitation, but will also allow a higher volume of fluid to be passed through the system. Helping keep fluid temps down, improve performance and longevity. This will come with a specially machined Mag-Hytec pan.

This Category 1 SunCoast Torque Converter fits 68RFE transmissions and is engineered to handle your everyday duties. Whether you're towing a camper or hauling dirt to a job site, this torque converter is designed to improve vehicle response and to give you years of reliable performance. It comes with furnace-brazed fins and hardened turbine splines. The clutches in this converter are carbon-graphitic for precise and accurate lock-up. If you are looking for increased performance over the factory unit and looking for a cost-effective solution this is the converter for you. 

This converter, while great for heavy duty towing and hauling, it is not intended for racing.
