2013-2018 Ram 6.7L Cummins Transmission Parts

About 2013-2018 Ram 6.7L Cummins Transmission Parts:

With all the problems that plague the transmissions of the 6.7L Cummins trucks (especially the 68RFE), the aftermarket has had to step up and provide solutions, and the good news is that it's been mostly successful. That being said, there's a ton of aftermarket parts and upgrades for the 2013-2018 Ram 2500 & 3500 6.7L Cummins out there, and it can be a bit of the pain to navigate all of the various 6.7L Cummins transmission parts and upgrades out there. Luckily for you, we here at Tier One are Dodge Ram transmission experts, and we're here to help you figure out everything you need to get your Ram's transmission fixed and ready to hold more power and handle tougher applications than your stock transmission alone.

2013-2018 Ram 6.7L Cummins Valve Bodies:

The factory valve body on the 68RFE transmission is the source of a ton of issues with the 6.7L Cummins Rams and swapping it out with a high-pressure 68RFE valve body or billet 68RFE valve body is a great way to win your transmission back both excellent functionality and long-term reliability all in one place. The factory valve body suffers from several design flaws that cause cross-leaks, pressure loss, and solenoid issues that can lead to weird shifting behavior, the dreaded P0871 trouble code, and a lack of lubrication to your Ram's other critical transmission components.

Aftermarket 68RFE valve bodies feature a ton of reliability and performance improvements that can give your Ram 6.7L Cummins back excellent transmission function and longevity all in one place. Tier One's own 07.5-18 Ram 6.7L Cummins 68RFE High-Pressure Valve Body and our 07.5-18 Ram 6.7L Cummins 68RFE Billet Valve Body generate higher line pressures than stock and come with a ton of improvements that reduce the chances of leaks and pressure loss, even when your Ram is generation a ton more horsepower and torque than stock. Tier One's billet valve body includes a billet channel plate and can handle applications of over 1000 horsepower.

2013-2018 Ram 6.7L Cummins Transmission Pumps:

The stock transmission pump on the 68RFE transmissions can suffer from some issues that lead them to produce lower pressures than what's ideal for your Ram's transmission, which can lead to sub-optimal line pressures which can give your truck weird shifting behavior, as well as a lack of lubrication for your Ram's critical transmission components. Both of these are "bad things" which can have huge consequences for how your Ram 6.7L Cummins drives and how long its transmission will last.

Aftermarket transmission pumps feature design improvements that fix both common reliability issues with the factory pumps, and can generally handle much higher power levels without deflection or power losses. Some of these pumps even come standard with billet pump bodies that are perfect for extremely high-horsepower Ram 6.7L Cummins builds.

2013-2018 Ram 6.7L Cummins Thermal Bypass Valves:

The stock thermostatic valve on your Ram 2500 or 3500 is not a huge part of your truck's transmission, but it's a failure-prone component that can lead a lot of no-good-very-bad-things for your Ram's transmission. The stock thermostatic valve is a block with an integrated thermostat element that controls fluid flow from your Ram's transmission to its transmission cooler. The valve stays closed until your Ram's transmission fluid reaches an optimum temperature, then it opens and allows fluid to flow out to your Ram's transmission cooler. Unfortunately, that thermostat element likes to fail or get clogged with debris which makes it get stuck closed and keeps hot transmission fluid flowing back into your Ram's transmission.

Thermal bypass valves for 2013-2018 Ram 2500 & 3500 trucks work by deleting the thermostat element in its entirety, which removes a potential point of failure that can seriously hurt your Ram's transmission. Thermal Bypass valves are essentially billet blocks that install in place of the factory thermostatic valve and allow full-time coolant flow to your Ram's transmission cooler. Some of these bypass valves even come with magnetic maintenance plugs that help pull grime and debris out of your Ram's coolant, which helps reduce the chance of them getting clogged. 2013-2018 Ram 6.7L Cummins thermal bypass valves are inexpensive, easy to install, and don't require tuning, making them perfect for essentially any Ram 6.7L Cummins build.

2013-2018 Ram 6.7L Cummins Transmission Coolers:

It's a well-known fact that the 6.7L Cummins Rams and their transmissions produce more than a little heat, which can be a bit of problem when you start to tow heavy, rip around in got climates, stack on powerful tunes and other aftermarket parts, or some combination of the three and your Ram's transmission temperatures start to hit critical levels. Unfortunately, the factory transmission cooler just can't keep up with the heat production that tends to happen in tough applications like towing heavy uphill at fairly low speeds, or when your truck is throwing down more power from turbo upgrades and aggressive tuning.

Performance transmission coolers for 2013-2018 Ram 6.7L Cummins trucks can drastically reduce your Ram's transmission temperatures, even when you're towing extremely heavy loads with your tough truck. We here at Tier One have both drop-in transmission coolers auxiliary transmission coolers available that improve heat dissipation over stock and keep your transmission running cool. Drop-in transmission coolers install right in place of the factory transmission cooler and feature larger surface areas, thicker cores, and more efficient designs than stock so that you get improved cooling in an easily-installed package. Ram 6.7L Cummins Auxiliary coolers install in addition to your stock cooler (or an aftermarket replacement cooler) to give your Ram insane levels of cooling for extreme towing, track use, or extremely hard off-road driving. While auxiliary transmission coolers are a bit tougher to get up and running on your truck, they provide awesome levels of cooling potential.

2013-2018 Ram 6.7L Cummins Transmission Pans:

Swapping out the stock transmission pan may not seem like that huge of a priority versus other transmission components, but the stock transmission pan doesn't do a lot for you that you probably don't even realize. The stock transmission pan doesn't come with a drain plug, which makes a swapping out your Ram's transmission fluid and filter a giant pain in the neck. The stock pan is also made out of stamped steel which isn't the most effective material for dissipating heat, and its design doesn't let it hold as much fluid as it possibly can.

Aftermarket deep transmission pans for 2013-2018 Ram 6.7L Cummins trucks not only make fluid changes a whole heck of a lot easier thanks to their built-in drain plugs, but they also help keep your Ram's transmission temperatures under control. Ram Cummins deep transmission pans are made out of cast aluminum which is far more effective at dissipating heat than the stock pans which helps reduce transmission temperatures when you're pushing your truck extremely hard. The deep design of these pans also allow them to hold more transmission fluid than stock, and that increased fluid volume serves as a heat sink, as well as improving lubrication for your Ram's transmission. Transmission pans are easy to install, and are a hassle-free upgrade for practically any Ram 6.7L Cummins build.
