Put the ultimate transmission in your 2003-2007 Dodge 5.9L Cummins 2WD with the CA Conversions Allison Conversion Kit. Custom Automatic (CA) Conversions has put years of research and development into providing you with the components needed to put a 5 or 6-speed Allison 1000 or 2000 series transmission behind your Cummins. With their uniquely designed programming, CA Conversions has optimized the function and performance of the Allison transmission giving you the most efficient use of your transmission, also maximizing the power and fuel efficiency of your engine.Â Many Dodge Cummins owners are on their 2nd and 3rd transmissions. Unlike the factory Dodge transmission, the reputation of the Allison Transmission has been proven! Featuring a tried and true heavy-duty design, the Allison is arguably the strongest transmission ever manufactured for a pickup truck of any kind. The Allison 1000 found in a Duramax pickup is the same transmission found in an International, Freightliner, and many other medium duty trucks. No other pickup manufacturer can make the same claims! Putting an Allison Transmission behind your Cummins gives you a "Million Mile Solution".Â To get a conversion kit for your truck, identify the Allison Transmission you plan on using, and select from the options above to build your CA Conversions Allison Conversion Kit.Â Flex Plate & Adapter CA Conversions specially designed adapter and flex plate allows you mate your Cummins engine to the Allison transmission.

All 6-speed wiring harnesses have the tap shift function.Â Transmission Cooler HosesÂ An essential part to properly cooling your transmission, CA Conversions Transmission Cooler Hoses are available in #8 or #10 depending on the size of your bell housing cooler ports.
