The BD Diesel 48RE Transmission & Converter Package, part number 1064194BM, is designed for heavy-duty Dodge Ram applications from 2003 to 2004. This comprehensive upgrade enhances transmission durability, efficiency, and performance, making it ideal for towing, high-horsepower modifications, and fleet use. The package includes a fully rebuilt transmission with high-performance components and a custom-tuned torque converter for optimized street and towing operation. Crafted with precision, the transmission features an upgraded valve body, a high-pressure governor transducer with twice the burst strength of stock, and a billet input shaft capable of handling rapid throttle and high horsepower stresses. The reinforced manual valve ensures reliable lubrication in all positions, while the roller Torrington bearings replace stock thrust bushings for increased longevity.
Additional features include a heavy-duty aluminum transmission pan with heat-dissipating fins that add two quarts of extra oil capacity and reduce operating temperatures. The BD auxiliary full-flow filter kit provides extra protection for the transmission fluid, ensuring long-term reliability. The drilled intermediate shaft promotes better lubrication, and the pan’s magnetic drain plug facilitates easy maintenance. The package is completed with a high-performance, street/towing stall torque converter featuring machined positions for improved engagement, less heat, and better fuel economy. Every transmission is dyno-tested to ensure quality and performance consistency. Designed with durability in mind, this upgrade also includes a fortified cast aluminum stator, stamped-forged steel front cover, and an upgraded clutch count for increased torque capacity. This product is not intended for race or sled pull use but offers a 36-month/150,000-mile parts warranty and a 12-month/24,000-mile labor warranty, providing peace of mind for demanding applications.
