ATS SWAP CUMMINS TO ALLISON CONVERSION KIT-COMPLETE CONVERSION KIT

ATS Swap Cummins to Allison Conversion Kit

Fitment: 2007½-Current Dodge Ram 6.7L Cummins

⚠ Important Note: If your vehicle is equipped with a 68-RFE transmission, the ECM must be flashed to a factory external ECM Aisin® option calibration. This reflash is recommended during the Allison installation to ensure proper communication between the engine and the transmission. For trucks equipped with an Aisin® transmission, no ECM reflash is required.

• Fully Integrated Allison Transmission Swap: Converts your Dodge Ram 6.7L Cummins to an Allison LCT1000 transmission, maintaining all factory functions and performance.
• TRANSLator® Technology: A proprietary, plug-and-play solution that allows the Allison TCM to communicate with the Ram ECM, ensuring seamless integration.
• No Additional Fabrication Needed: The ATS exclusive, patent-pending Cummins to Allison Bellhousing ensures a perfect fit without any modifications to the engine or transmission.
• Comprehensive Conversion Kit: Includes all necessary hardware and software for a complete Allison swap, including the Bellhousing, TRANSLator module, TCM, shifter, and more.
• Supports Higher Torque Loads: The Allison transmission’s larger shafts, clutch packs, and gear sets are engineered to handle the Cummins engine’s high torque output, outperforming Dodge’s factory transmissions.
• Perfect for Modified Engines and Heavy Towing: Ideal for trucks with oversized tires, engine upgrades, or those towing heavy loads over long distances.

The ATS Swap Cummins to Allison Conversion Kit is engineered for Dodge Ram 6.7L Cummins owners who demand more from their trucks. ATS Diesel’s innovative solution enables you to swap your factory Dodge transmission for the superior Allison LCT1000 6-speed automatic transmission, providing unmatched reliability, performance, and drivability. Powered by ATS's proprietary TRANSLator® CAN-bridge module, this kit ensures seamless communication between the Allison Transmission Control Module (TCM) and the Ram Engine Control Module (ECM). All factory options—including push-button start, tow/haul mode, adaptive cruise control, electronic transfer case, and electronic range select—are retained with no loss of functionality.

Dodge Ram trucks have historically been equipped with less robust transmission options, such as the 48RE and 68RFE, which have smaller shafts, clutch packs, and gear sets. While these factory transmissions can be upgraded to handle higher power levels, they still lack the inherent strength and refinement of the Allison transmission. The Allison LCT1000 is built with much larger internal components, making it an ideal choice for trucks with modified engines, those that tow heavy loads, or those running oversized tires.

The Allison transmission provides smooth shifts across all 6 gears with less RPM drop between shifts, enhancing drivability and performance. Compared to the Dodge 4-speed automatic transmissions, the Allison offers more efficient power transfer, improved fuel economy, and greater durability. The 6-speed gear split of the Allison ensures consistent power delivery, with the torque converter’s PWM (Pulse Width Modulation) design allowing precise clutch engagement, resulting in smooth, controlled shifts that are especially beneficial for towing and heavy-duty applications.

This complete conversion kit from ATS Diesel includes everything needed to install an Allison LCT1000 behind your Cummins 6.7L engine, eliminating the complexity of a typical transmission swap. The patent-pending Cummins to Allison Bellhousing allows a perfect bolt-up installation without the need for grinding or engine modifications. The ATS TRANSLator® module bridges the communication gap between the TCM, ECM, and Body Control Module (BCM), ensuring that key vehicle functions—like cruise control, remote start, rearview camera, speedometer calibration, and four-wheel-drive operation—continue to work as they did from the factory.

Key Features:

• TRANSLator® Technology: Bridges the communication between the Allison TCM and Ram ECM, ensuring all factory functions work as intended.
• Allison 6-Speed Transmission: A more robust alternative to Dodge’s 4-speed and 6-speed automatics, featuring larger clutch packs, gear sets, and shafts for greater durability.
• Smooth, Reliable Shifts: The Allison offers smoother gear transitions with less RPM drop, improving overall drivability and fuel efficiency.
• Factory Fit Bellhousing: Patent-pending design allows a direct bolt-up to the Cummins engine, eliminating the need for additional modifications or adapter plates.
• Complete Conversion Kit: Includes Bellhousing, TRANSLator module, wiring harness, shifter, TCM, and all necessary hardware for installation.
• Perfect for High-Torque Applications: Ideal for trucks with modified engines, heavy towing, or those equipped with oversized tires.

Increased Performance & Reliability:

If you’re towing heavy loads, running engine upgrades, or simply want more from your transmission, the Allison LCT1000 is the superior choice. It provides smoother shifts, increased power handling, and more robust internal components compared to Dodge’s 47RE, 48RE, and 68RFE transmissions. The Allison’s larger clutch packs, shafts, and gear sets are specifically designed to handle the high torque of the Cummins engine without sacrificing drivability.

For owners of trucks equipped with the Dodge 48RE or 68RFE, which rely on older technology like hydraulic throttle valves and governor pressure for shift control, upgrading to an Allison provides more consistent shift timing, better power delivery, and enhanced fuel efficiency. The 68RFE in particular, designed with components similar to those used in gas engines, has long struggled with reliability in high-torque diesel applications. By contrast, the Allison’s electronically controlled gear splits and more efficient torque converter make it the ideal transmission for those looking to optimize towing performance or high-horsepower setups.

Important Notes:

• ECM Reflash Required: For vehicles equipped with the Dodge 68-RFE transmission, the ECM must be flashed to the Aisin® option calibration for proper communication with the Allison transmission.
• Plug-and-Play Installation: The kit includes all necessary hardware and electronics, ensuring a straightforward installation with no cutting or additional fabrication required.
• Perfect for High-Torque Applications: Ideal for modified Cummins engines, heavy towing, and high-power setups, the Allison provides a significant upgrade in terms of reliability and performance over Dodge’s factory transmissions.
