2019-2024 Ram 6.7L Cummins Transmissions

About 2019-2024 Ram 2500 & 3500 6.7L Cummins Built Transmissions

The factory transmission, especially in the case of the 68RFE, is one of the biggest weak points on the 2019-2024 Ram 6.7L Cummins trucks, and while you can try replacing parts as they fail or guessing which component is going to fail next, your best bet may be a complete transmission, and we here at Tier One specialize in the manufacture and installation of built Dodge Ram transmissions that can hold more horsepower than stock and can handle much more aggressive applications than the factory transmission without letting you or your truck down. Tier One's Dodge Ram transmissions come with a ton of different upgrades that make them the perfect choice for practically any Ram truck build. We here at Tier One offer several different levels of our transmission builds so that you can find the perfect built Ram transmission for your truck's power level, application, or budget. Our various stages can get a little confusing, so here's a bit of rundown on Tier One's built transmission offerings.

2019-2024 Ram 6.7L Cummins Towing Transmissions:

Tier One's built 2019-2024 Ram 6.7L Cummins HD Tow 68RFE Transmission and 2019-2024 Ram 6.7L Cummins HD Tow AS69RC Transmission are our more budget-friendly Dodge Ram built transmissions that come with just enough upgrades to improve reliability on trucks that are at stock or near-stock levels of power from mild tuning or basic bolt-on parts like cold air intakes and upgraded intercoolers.

- Our 2019-2024 Ram 68RFE HD Tow Transmission comes with one of our 68RFE High-Pressure Valve Bodies, a twin-disc torque converter, and a 68RFE PPE deep transmission pan. These upgrades are just enough to increase your transmission's reliability and fix some of the weak points of the 68RFE, though if you're running a decent amount more power than stock, this transmission isn't for you.

- Our 2019-2024 Ram AS69RC HD Tow Transmission comes with an HD torque converter, performance valve body, and an AS69RC PPE deep transmission pan. The AS69RC tends to be more stout than the 68RFEs, and we include a few upgrades that help improve its reliability when towing heavy and consistently. However, Tier One's AS69RC towing transmission is still only meant for stock or near-stock power levels, and if your truck is running aggressive tunes or a bigger turbo, you'll probably want to step up.

2019-2024 Ram 6.7L Cummins Stage 1 Transmissions:

If your Ram is running extra power and torque from fairly aggressive tuning or mild turbo upgrades like a Fleece Cheetah or an ATS Aurora 3000, our HD Tow series won't be enough to reliably handle the increase in power and torque. For Ram trucks that are throwing down a good amount more power than stock and running slightly more power, but still towing heavy, then you'll want to jump up to our Ram Cummins Stage 1 transmissions. Our 2019-2024 Ram 2500 & 3500 6.7L Cummins Stage 1 68RFE Transmission or our 2019-2024 Ram 3500, 4500, 5500 6.7L Cummins Stage 1 AS69RC Transmission have even more upgrades than our HD Tow transmissions that allow them to handle more power, heavy towing, and tough off-roading without letting you or your truck down.

- Our 2019-2024 Ram 68RFE Stage 1 Transmission comes with a billet twin-disc torque converter, billet 4C retainer, deep transmission pan, and a Tier One 68RFE High-Pressure Valve Body. The addition of a billet twin-disc converter and a billet 4C retainer allow for increased power-holding and fixes the issues of a 4C snap ring failure from wrecking your day when your truck is running at increased power levels. The Stage 1 68RFE transmission is rated for up to 600 crankshaft horsepower.

- Our 2019-2024 Ram AS69RC Stage 1 Transmission comes with a billet 6-disc torque converter, billet K2 clutch hub, new clutch module with GPZ clutches, and a deep transmission pan. The improved billet torque converter, billet hub, and improved clutches all increase the transmission's ability to hold power. The billet K2 hub also fixes a potential issue of the stock hub getting gouged by the clutches when placed under load so that you get reliable operation even at higher power levels and heavy towing. The Stage 1 AS69RC transmission is rated for up to 600 crankshaft horsepower.

2019-2024 Ram 6.7L Cummins Stage 2 Transmissions:

When your Ram is running big turbos, oversized injectors, and aggressive tuning or when you're pushing your truck hard on the street, towing heavy, or hitting the occasional sled pull, then you're going to need a transmission that can hack it. Tier One's 2019-2024 Ram 2500 & 3500 6.7L Cummins Stage 2 68RFE Transmission and our 2019-2024 Ram 3500, 4500, 5500 6.7L Cummins Stage 2 AS69RC Transmission are designed specifically for trucks that are churning out some serious horsepower and torque while still being a streetable, easy-shifting truck. Tier One's Stage 2 transmissions are perfect for trucks that are moderately modified or being used in extremely heavy towing or ripped around hard off-road or down at the occasional sled pull.

- Our 2019-2024 Ram 68RFE Stage 2 Transmission comes with a billet triple-disc torque converter, billet flex plate, billet input shaft, billet input clutch drum, billet 4C retainer, billet 2C piston, rollerized sprag, a Tier One 68RFE Billet High-Pressure Valve Body, and a deep transmission pan. Jumping up to a triple-disc converter, billet input shaft, billet clutch hub, and billet valve body all allow the transmission to handle much more power than the Stage 1 system. The end result is a transmission that can handle big turbo builds that are going to see some aggressive use on the street or out in the dirt. The Stage 2 68RFE is rated to handle up to 750 horsepower.

- Our 2019-2024 Ram Stage 2 AS69RC Transmission comes with a 6-disc billet torque converter, a performance valve body, billet K2 hub, billet K3 drum, billet K2 piston, billet K2 piston, new friction module with GPZ clutches, and a deep transmission pan. The addition of the 6-disc torque converter and a full suite of billet hubs, drums, and pistons all allow the transmission to hold a whole bunch more power and torque than the Stage 1 AS69RC transmission. The Stage 2 can hold up to 1000 crankshaft horsepower, which lets you use huge turbos, massively oversized fuel injectors, higher-flow CP4s or CP3 conversions, and extremely aggressive tuning without letting you down. The Stage 2 AS69RC is perfect for dedicated towing, hard off-road use, sled-pull use, and even the occasional use down at the track.

2019-2024 Ram 6.7L Cummins Stage 3 Transmissions:

While our AS69RC transmissions top out at Stage 2, our 2019-2024 Ram 2500 & 3500 6.7L Cummins Stage 3 68RFE Transmission takes power to the next level. The Stage 3 68RFE transmission is a great go-between if your truck is pushing out a bunch of power, being used as a dedicated tow rig, seeing some time down at the sled pull, but isn't quite an out-and-out competition build. The Stage 3 transmission takes the Stage 2's upgrades to the next level and lets you use big turbos, extremely high-flow injectors, upgraded lift pumps and CP4s, and really aggressive tuning while still maintaining decent shifting and street drivability.

- Our 2019-2024 Ram 68RFE Stage 3 Transmission comes with a billet triple-disc torque converter, billet flex plate, billet maraging steel input shaft, billet input clutch drum, billet outer drum, billet center support, billet overdrive clutch hub, billet 4C piston, billet 4C retainer, billet 2C piston, rollerized sprag, a Tier One 68RFE Billet High-Pressure Valve Body, and a deep transmission pan. The jump up to a billet maraging steel input shaft, billet outer drum, billet overdrive clutch hub, and billet pistons allow the transmission to hold more power and better hand the shock and torsional strains from hard shifting under huge levels of load. The Stage 3 68RFE transmission can hold up to 900 crankshaft horsepower and is a great choice for powerful, weekend warrior trucks that are going to see some hard use on the street, off-road, at the sled pull, or even at the track or dyno day.

2019-2024 Ram 6.7L Cummins Competition Transmissions:

If you're putting together a Ram Cummins build that's destined for the track, sled pull, or dyno day, then you're going to need a fully-built 68RFE transmission that can hold tremendous levels of power and torque in the toughest applications on the planet. The Tier One 2019-2024 Ram 2500 & 3500 6.7L Cummins 68RFE Competition Transmission features basically every upgrade you can throw at a 68RFE, letting it hold a ludicrous level of power and handle extreme drag strip, dyno, and sled pull applications without letting you or your Ram down. The Competition 68RFE transmission is so strong, even we don't know how much power it can handle, though we're trying hard to find the limit. If your Ram is going for massive power and podium finishes, the Tier One 68RFE Competition Transmission is your best bet.

- Our 2019-2024 Ram 68RFE Competition Transmission comes with a billet triple-disc torque converter, billet flex plate, billet maraging steel input shaft, RevMax billet XR clutch drum, RevMax billet center support, billet overdrive clutch hub, billet 4C retainer, billet 4C piston, billet 2C piston, billet rollerized sprag, Tier One Billet High-Pressure Valve Body, and deep transmission pan. The jump up to the RevMax XR drum and billet rollerized sprag allow the competition transmission to hold a whole bunch more power and handle the high shock and massive loads that come with huge-power Ram builds and extremely hard use down at the track or on the dyno. This transmission is so bullet-proof, even we aren't sure what it's maximum power holding tops out at.
