The 68RFE in the Ram 6.7L Cummins has been around longer than a certain popular touchscreen tablet. In the last 14 years, some of those have been through many owners, towing jobs, stoplight to stoplight pulls, and teaching youngsters how to drive. They've suffered through a lot of heat, and electronic tuning. SunCoast offers a cost-effective solution to revive your drivetrain in your 2007.5-2019 Ram with their Category 1 Transmission. With an approach centered in science and study, this 450HP capable transmission has been built with heavy towing and street driving in mind. Below are some of the highlights of their build.

The Torque Converter

The Guardian SunCoast Torque Converter fits 68RFE transmissions and is engineered to handle everyday duties. Towing a camper or hauling dirt to a job site, this torque converter is configured to improve vehicle response and give you years of solid, reliable performance. It comes with furnace-brazed fins and hardened turbine splines. Improving on a common factory failing point, the clutches in this converter are carbon-graphitic for precise and accurate lock-up. While there is an increase the in performance over the factory unit and is a cost-effective solution, this converter is great for heavy duty towing and hauling, however it not intended for racing. Plan accordingly.

The Category Transmissions

The SunCoast Category 68RFE transmissions are designed and developed with the systematic approach to solving the issues with the 68RFE transmission.  SunCoast approaches each deficiency and failure point and need from a scientific approach.

The Smart Tech Drum

The 68RFE's factory overdrive clutches are at high risk of failure when towing or installing aftermarket programmers, delete kits, or larger turbos. This is in large part to the fragile and thin (.034) single-sided clutches. When exposed to increased torque or higher temperatures, they will distort, causing additional clearance and uneven pressure application. This will always result in burnt clutches. The clutches in the overdrive housing are by far, reportedly, the weakest link in the 68RFE transmission design.

SunCoast utilizes Sonnax Smart Tech 68RFE overdrive drums to address these issues. The new billet clutch housing holds a physically taller clutch pack, allowing the overdrive clutch area to increase 16%. In addition to the increased application to surface area, the thicker clutches and steels increase clutch steel mass by 28%, drastically improving the heat dissipation and aiding in transmission longevity.

The new 68RFE overdrive clutch drum also comes with a top bolt-on plate to help eliminate clutch pack flexing and distortion that contribute to premature failure.

The 2C Piston

The factory molded piston is prone to uneven application which leads to excessive heat in the clutches and steel leading to premature failure. In the 68RFE Category 1 Transmission, SunCoast replaces the factory piston with a greatly improved billet piece that also allows for an additional clutch further increasing surface supply area.

The Ducenti

SunCoast is proud of its Pro-Loc Ducenti 200psi Shift Calibration Kit for the 68RFE. SunCoast put together a solution after years of continuing research and refinement. In this valve-body, several key issues within this hydraulic circuit were addressed using a multi-faceted approach. The kit includes everything you will need to achieve 200psi without any additional tuning and is designed to be a complete drop-in, resulting in firmer, quicker gear changes aiding further in transmission longevity.

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.

The Solenoid Pack

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

Zero Cavitation Filter Kit

The factory 68RFE has had many issues with the pressure relief check valve system in the transmission pan filters. Initially, there were issues with the plastic filter splitting in half. This was later remedied by adding a pressure relief valve on top of the filter. This later proved to be an issue, as the valve would release itself from the filter all together.

The Zero Cavitation Filter Kit is a bottom feed filter kit allowing the usage of a torqueflite filter. This filter conversion will not only prevent pump cavitation, but it will also allow a higher volume of fluid to be passed through the system.

Treats and plenty of ball throwing with these doggie toy
Size: Medium (2.5"), Style: Fetch Pack 1
I have actually purchased these twice already. I love the one that glows in the dark but it still got lost in my yard lol. My dog is a big breed half pitt/Labrador so she did chew through one of them already. I play ball with her every single day but I DO have to take them away from her because she will destroy them. They are great to add in treats as well, that was one of the my favorite things about them as well. They do last just if you have an over zealous chewer do not let them keep them for long periods of time. They are a good value for the price. Buy them your dog will love it!

My Female GSD loves
Size: Medium (2.5"), Style: Fetch Pack 1, Size: Medium (2.5"), Style: Fetch Pack 1
Shasta is my smallest. Six in December (2025) along with her brother. She’s 100 lbs and outside, completely ball driven see last picture. Don’t let the size (2.5”) of these Chuck-It balls deter you. If your larger Breed dog has any orthopedic issues, has already torn their ACL etc, one has arthritis but wants to play. This size is perfect! Shazzy was born with several ortho issues. I don’t throw balls distance but right to her. This size and lighter weight assure even when Shazzy is spazzy w excitement, she’ll catch the ball mid air. The green balls are softer, and glow in the dark. In summer we can play well past dusk and I can see them! Her personality shows in the pictures. Playing ball is part of her. These balls are just perfect for her situation. Somehow they disappear, she loves making baskets, puts them in my tractor bucket, or my gardening bucket..then get put in burn pile, trash etc. I keep replacing them because she’d look day and night if we actually ran out!! 🙏✝️👍🏼👍🏼

Perfect for Blind Dogs, Fun and Durable
Size: 2-pack, Style: Duo
My blind dog loves these Chuckit! sniff balls. She can easily sniff them out and plays fetch with them for 20 minutes a day, even running up and down the stairs. The balls are durable, bounce well, and the bacon and peanut butter scent keeps her engaged. I do wish Chuckit! would bring back the version with a tone so we could play fetch outside more easily. Overall, a fantastic toy for dogs that rely on scent and a fun way to keep them active.

My Golden Loves
Size: 2-pack, Style: Duo
My 8 month old Golden Retriever loves these. It is also one of the few products she cannot destroy. They smell as described and she loves to chew them and play fetch when. She can chew these easily without destroying them. Overall good value for the money for my Golden
