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.

Not for small animals
I bought these for my ferret and even though it’s hard for her to pick up, they’re so cute and soft.

Squeaker Shenanigans!
I have four large dogs - 65-70 lbs, pittie babies. Three out of four love, love, LOVE squeaker toys. You can't keep a squeaker toy in my house to save your life. If it squeaks, it dies a quick squeaker death. We generally buy squeak toys at the Dollar Store. My going theory on toys is it has to last one minute per dollar I spend on it. Then I call it "worth the money." Right now, it is winter and where I live, so very cold. My kids can't get all their energy out by being outside, so we have to come up with creative indoor fun. I like these types of packs of toys, one for the value and two the quantity. I put all the toys in a box, and then my kids get to come up and pick one out of the box - they then run off for the squeaker toy of destruction fun! Squeak! Squeak! Squeak! Death. One kids goes right to hunting for where the squeaker is inside the toy, and the hunkers down to figure out how to get it out and kill it. She is usually the 60 seconds or less, 1st Place Squeaker Death Winner. The other two, will take their time and enjoy the squeaks and work the squeaker out until death finally takes it. My 70 lb boy, is kind of a baby, and after he neatly gets his squeaker out, he makes the toy his baby, and then carries it around proudly. Considering how large my kids are, these are well made and take the full minute for Squeaker of Death girl to get the squeaker out. The size is great, even for my larger dogs. I got nine toys for about $12 at the time of this purchase, and it was perfect. It did come with the storage bag...but not something that is necessary in this house. Although, it was actually quite nice, and I am sure I can use for something else. The Sun was a big hit, and despite not having its squeaker anymore, is still hanging around, days later. I will be buying this pack again.

Pom approved!
My pomeranian ONLY plays with small stuffies that squeak. She loves these and they are just small enough for her to hold and squeak. They are durable enough - but we will see when her big dog cousins come play with her, just how sturdy they are! They are very cute, soft, and squeak well. Good value for the pack of them.

Goldilocks of dog toys!
We recently rescued a small/medium bulldog breed (35lbs) and she *loves* toys. Problem was that our other dog's (75lbs) toys were too big. They literally were the size of her. We found that our new baby pooch was constantly raiding our cat's bed with the cat toys. They were more her size and she knew it. I bought her some cat toys (mostly mice with catnip inside and a yarn tail). She *loved* them, but they were too small. She would choke on them and I would literally have to pull them out of her throat by the mouse tail. Scared us too much so we gave (all 20) away to a friend. I scoured Amazon and found these whimsical toys and they are *JUST RIGHT*! Perfect size, have held up several days of chewing and gnawing, squeak pretty well, and my big dog also loves them! These deserve the 4.9 (5.0 but can't please everyone) rating that lead me to purchase them in the first place. Buy with confidence for your medium size (or any size really) fur baby!
