Chevrolet Silverado 2500 Transmission & Converter Package - BD Diesel Roadmaster Allison (2017-2019). Built for reliability on L5P-powered 2500s, it pairs a BD-upgraded Allison 1000 with a matched ProForce torque converter.

Built for stock or mildly modified use, the Roadmaster raises line pressure by up to 68% via a revised valve body, increasing clutch-pack torque capacity. BD's deep aluminum pan adds about 3.5 extra quarts and helps control transmission temps while towing. Tuned for the 6.6L L5P and Allison 1000, it delivers durable performance and consistent shifts. Fits 2017-2019 Silverado 2500 6.6L Duramax, 2WD.
