Allison Conversion Install Kit

Features

• Seamlessly replaces the factory 68RFE transmission with a customer-supplied Allison LCT1000 6-speed automatic

• TRANSLator module ensures full communication between Allison TCM and RAM ECM/BCM

• Maintains OEM functions: push-button start, tow/haul mode, tap shifting, range select, and 4x4 low-range (if applicable)

• Plug-and-play wiring harness included — no engine block grinding, custom flexplates, or starter mods required

• Custom cast Cummins bellhousing and extension housing for factory-aligned bolt-up

• Preserves factory shifter usability; optional ATS shifter available for older applications

• Advanced electronics integration retains cruise control, rearview camera, gear indicators, and more

• Transmission adapts to driver behavior for optimal shift quality and torque management

• Ideal for towing, oversized tires, and high-horsepower applications where the 68RFE struggles
