Built Transmissions for 2013-2018 Ram 2500 & 3500s from Tier One:

It's not exactly a secret that the Rams don't have the strongest transmissions in the world. Unfortunately, the issues weren't fixed for the 2013-2018 Ram 2500 and 3500 trucks, and their transmissions remain a problem area, even at stock power levels. The Chrysler 68RFE is especially notorious for their unreliability and their multiple points of failure. We here at Tier One offer 2013-2018 Dodge Ram built transmissions that can hold serious levels of horsepower and torque and handle the toughest applications on the planet without letting you or your tough Ram truck down. We here at Tier One offer both built 68RFE transmissions and built AS69RC transmissions available in several different variations so that you can find the perfect transmission for your Ram's power level, intended application, or your budget.

2013-2018 Ram 2500 & 3500 6.7L Cummins Towing Transmissions:

Towing heavy loads puts a lot of strain on your Ram's transmissions, and both the 68RFE and AS69RC transmissions can use some upgrades in order for them be reliable when you're towing heavy loads. Tier One's 2007.5-2018 Ram 6.7L Cummins 68RFE HD Tow Transmission and our 2013-2018 Ram 6.7L Cummins AS69RC HD Tow Transmission feature just enough upgrades to let these transmissions better handle heavy towing, off-roading, and street driving at factory power levels or with mild tuning and basic bolt-on parts. Tier One's HD Tow transmissions are budget-friendly (for complete transmissions) and are a great choice for anyone who wants more reliability without going too crazy.

2013-2018 Ram 2500 & 3500 6.7L Cummins Stage 1 Transmissions:

Tier One's Stage 1 built transmissions feature a number of upgrades over the stock 68RFE and AS69RC transmissions that allow them to handle a good amount more power than stock, and are good choices for Ram 6.7L Cummins trucks that are using fairly aggressive tuning, and even mild turbo upgrades like Fleece Cheetahs or ATS Aurora 3000s. The 2007.5-2018 Ram 2500 & 3500 6.7L Cummins 68RFE Stage 1 Transmission and the 2013-2018 Ram 3500 6.7L Cummins AS69RC Stage 1 Transmissions are both rated to 600 crankshaft horsepower, making them perfect for Ram Cummins trucks running with a few mods, towing heavy, and rocketing around off-road on big tires. While our Stage 1 transmissions probably can't handle track or sled-pull use, they're rocking enough upgrades for your average street, towing, and trail-riding Ram 6.7L Cummins build.

2013-2018 Ram 2500 & 3500 6.7L Cummins Stage 2 Transmissions:

Ram's that are rocking big-time horsepower and torque are going to need a seriously built transmission to hold it all. Tier One's 2007.5-2018 Ram 6.7L Cummins 68RFE Stage 2 Transmission and 2013-2018 Ram 6.7L Cummins AS69RC Stage 2 Transmission can hold a bunch more power than stock, letting you add some serious power-adders to your tough 6.7L Cummins Ram build without needing to worry about your transmission letting you down. Tier One's Stage 2 68RFE transmission is rated to handle up to 750 crankshaft horsepower, giving it the ability to handle aggressive performance tuning, big turbos, slightly oversized injectors, and full bolt-on parts without giving up the ghost. Tier One's Stage 2 AS69RC transmission is rated it to handle up to 1000 crankshaft horsepower, which lets you stack on extremely big turbos, upgraded CP4s or CP3 conversions, extremely powerful custom tunes, and other potent power-adding components while still letting you tow and haul heavy loads.

2013-2018 Ram 2500 & 3500 6.7L Cummins Stage 3 Transmissions:

Rams that are seeing some seriously big power, but still aren't dedicated competition rigs are going to need our 2013-2018 Ram 2500 & 3500 6.7L Cummins Stage 3 68RFE Transmission. The Stage 3 68RFE transmission can hold up to 900 crankshaft horsepower, which lets you put together one heck of a Ram build that still gets fairly smooth shifting on the street. The Tier One 68RFE Stage 3 transmission is a great choice for Rams that are rocking big turbos, massively oversized injectors, lift pump upgrades, big CP4s or CP3 conversions, extremely aggressive custom tuning, and nearly anything else you can throw onto your high-powered Ram build. The Stage 3 transmission also great for very heavy towing, tough off-roading with big tires, occasional track use, and trips down to your local sled pull.

2013-2018 Ram 2500 & 3500 6.7L Cummins Competition Transmission:

If you're putting together an immensely powerful Ram 6.7L Cummins build that's going to see hard use at the drag strip, sled pull, or dyno day, it's going to need a fully-built transmission that's going to handle the power and the forces of hard launches. The Tier One 2007.5-2018 Ram 6.7L Cummins 68RFE Competition Transmission comes with a ton of different upgrades that allow it to handle some of toughest applications on the planet.

The Tier One 68RFE Competition transmission can handle compound turbo builds, massively oversized fuel injectors, total fuel system overhauls, nitrous or water-meth injection, and practically anything else you want to do with your track-ready Ram 6.7L Cummins build.

Top 2013-2018 Ram 6.7L Cummins Transmission Parts

If a complete transmission sounds like a bit much for your tough Ram truck or if you just don't have the budget, we here at Tier One still have more than a few individual 2013-2018 Ram 6.7L Cummins Transmission Parts available that can help shore up your Ram's transmission against potential issues and to handle much more horsepower and torque than stock. Unfortunately, there's more than a few transmission parts available for the Ram 6.7L Cummins trucks which can make it tough to figure out where to start.

68RFE Valve Bodies: the factory valve body inside your Ram's 68RFE is the source of a ton of the Ram 6.7L Cummins' transmission issues, and swapping it out with a performance, high-pressure valve body is a great way to get your truck's transmission running reliably and holding more power than stock. The OEM valve body can cause your transmission to suffer from weird shifting behavior, burnt-out clutches, fluid starvation for critical components, and other issues that can all cause problems with your transmission or even outright cause a failure. Aftermarket 68RFE valve bodies have much higher line pressures than stock which helps prevent poor clutch engagement and a lack of lubrication that can lead to the failure of your Ram's critical transmission components. We even carry a selection of billet 68RFE valve bodies that can handle extreme levels of power and torque so that you can stack powerful modifications and tuning onto your Ram 6.7L Cummins.

2013-2018 Ram 6.7L Cummins Thermal Bypass Valves: the stock thermostatic valve on your 2013-2018 Ram 6.7L Cummins may be a small part of your truck's transmission cooling system, but it can cause some big problems that can lead to high transmission temperatures, limp modes, or even transmission damage. Your best bet would be one of our Ram 6.7L Cummins thermal bypass valves. These bypass valves completely delete the thermostatic element to allow full-time fluid flow from your Ram's transmission to its transmission cooler so that you both eliminate a potential point of failure and keep your Ram's transmission temperatures under much better control.

2013-2018 Ram 6.7L Cummins Torque Converters: while the stock torque converter on your Ram 2500 & 3500 6.7L Cummins does its job just fine at stock power levels and during light towing, it can really let you down when you start to add power or tow heavy loads with your awesome Ram Cummins build. The good news is that we here at Tier One have a bunch of performance torque converters for 6.7L Cummins Ram trucks that can hold more power, handle heavy towing, and keep your Ram running reliably in basically any application that you have in mind for your Ram truck build. We here at Tier One have multi-disc, triple-disc, and billet 68RFE torque converters available so that you can find the Ram 6.7L Cummins torque converter that's perfect for your budget or specific application.

2013-2018 Ram 6.7L Cummins Transmission Pans: while a transmission pan isn't the flashiest transmission component in the world, and while the stock transmission pan does the job of holding in your truck's transmission fluid, adding an aftermarket deep pan to your Ram actually really help your 6.7L Cummins Ram out. Tier One's selection of transmission pans for 2013-2018 Ram 6.7L Cummins trucks can help reduce running temperatures, improve lubrication and make transmission fluid changes a whole heck of a lot easier. These 68RFE transmission pans and AS69RC transmissions pans are made out of cast aluminum, which dissipates heat much more effectively than the factory stamped steel pan. Aftermarket Ram transmission pans also hold more fluid than stock, which serves as both a heat sink for further reduced temperatures, as well as providing improved lubrication. Best of all, these transmission pans come standard with built-in drain plugs that make doing fluid and filter changes a whole heck of a lock easier than the stock pan.

2013-2018 Ram 6.7L Cummins Transmission Coolers: heat is the enemy of anything mechanical, and the 6.7L Cummins trucks generate a whole heck of a lot of heat that can not only send your truck into limp mode if transmission temperatures climb too high, but can hurt your transmission. Tier One's selection of transmission coolers for 2013-2018 Ram 6.7L Cummins trucks greatly reduce the running temperatures of your Ram's 68RFE or AS69RC transmission, even when you're towing heavy or tearing around off-road. Aftermarket Ram 6.7L Cummins transmission coolers have larger surface areas, thicker cores, and more efficient designs than the factory transmission cooler, giving you and your truck vastly improved cooling capability than stock. We here at Tier One have both drop-in replacement transmission coolers and auxiliary transmission coolers available so that you can find the perfect transmission cooler for your tough Ram truck.
