ATS 319-933-2464 Full Allison Transmission Conversion Kit Stage 3 | 2019–2024 RAM 2500/3500 6.7L Cummins AS69RC 2WD

The ATS Full Allison Conversion Kit Stage 3 is engineered to replace the factory 2WD Aisin AS69RC transmission on 2019–2024 RAM 2500/3500 trucks equipped with the 6.7L Cummins. This kit includes an ATS-built Allison transmission, deep transmission pan, billet input shaft, and billet intermediate shaft—delivering unmatched strength, durability, and performance for towing and high-power builds.

Seamless Factory Integration

Backed by ATS's proprietary TRANSLator technology and an exclusive patent-pending Cummins-to-Allison bellhousing, this conversion offers full integration with all OEM features:

• Push-button start

• Tow/haul mode

• Electronic range select

• Electronic transfer case functionality

The TRANSLator bridge module allows seamless communication between the Allison TCM and the RAM ECM, enabling a nearly plug-and-play installation and preserving every factory feature on your truck.

Why Choose the Allison Swap?

The Allison LCT1000 6-speed automatic outperforms Dodge's factory transmission offerings:

• Larger shafts, gearsets, and clutch packs from the factory

• Smoother shift quality with better gear spacing than the AS69RC

• No engine derate between shifts, improving drivability and torque transfer

The Dodge AS69RC, 68RFE, and older 48RE transmissions were not designed to handle the torque demands of the modern 6.7L Cummins without extensive upgrades. The Allison transmission, in contrast, is built to endure heavy towing, oversized tires, and high-stress conditions right out of the box.

Kit Includes (Parts Vary by Year & Model)

• ATS-built Allison 6-speed transmission with billet input and intermediate shafts

• Billet Five Star torque converter

• ATS deep transmission oil pan

• TRANSLator transmission controller with plug-and-play wiring harness

Installation Notes

• Estimated Install Time: 12 hours (professional installation recommended)

• Driveshaft Work: Some modification (shortening/lengthening) may be required based on the truck's year/model

• Fitment: Fully compatible with 2019–2024 RAM 2500/3500 6.7L Cummins (2WD, originally equipped with AS69RC)

Reliability, Longevity, and Power

ATS engineered this kit to be the most complete and reliable Allison conversion on the market. Whether you're towing cross-country, daily driving, or hitting the sled pull track, this kit gives your Cummins the bulletproof shifting and reliability it deserves—without losing a single factory function.
