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.

The Amazing, Original View of Sex, Marriage and Romance.
Format: Hardcover
Two words: So. Good. I hadn't read anything by John Mark Comer before, but now I'm definitely looking at reading his other books. The depth, honesty, intensity and openness of Loveology really makes it a great tool for getting God's perspective on some of the most important topics in life. So good. As a young man (not even in my twenties yet), this was a great, consuming, eye-opening book that I'm so grateful God allowed me to read. I saw a video for it on Jefferson Bethke's YouTube channel and knew from that moment that I needed to read it. Although it took a few months, I finally ordered the book and got in the mail a few days later. The information and perspective this book both gave me and enforced are priceless. If you're a young man (or "teenager), and a Christian one a that, you NEED to read this book. If you're a young woman (or "teenager"), and a Christian one at that, you also NEED to read this book. As the younger generation, this is stuff we need to get. We have our entire lives ahead of us, and the more things we do God's way the first time around, the more He can do through us and for us as we continue down our path for life. Sexuality, marriage, romance, and God's place in all of this has been so freaking warped and twisted in our spiraling American culture. We need God's truth on this topic like *crazy.* Everyone does, but especially Christian youth. God has amazing things for us to do, but we can't do those things if we have bad relationships, wrong views of sex or warped ideas of marriage standing in the way. And while this book is definitely not the only way for us to get this truth, it is an extremely good start.

A great dive into "love"
Format: Hardcover
A perhaps too easy-to-read book with an interesting perspective on the concept of love, sex, and romantic relationships. It provided for me a mostly pleasant confrontation with my beliefs about love. Props to the author for the ballsy somewhat "counter-cultural" content. Good read for all interested in the idea of love, regardless of one's belief.

MUST READ - Biblical Perspective of Sex and Relationships, Great Book For Late Teens
Format: Hardcover
This book gives a right on Biblical perspective of dating, relationships, sex and more. Every Christian parent should buy this for their older teenage kids. I bought this book for my 18 year old daughter. She took it to school and found out that several of her friends had heard about the author and were also reading it. Her boyfriend is reading it now too. The Q&A portion at the end of the book is so good.
