The BD Diesel 1030311F transmission upgrade is designed specifically for heavy-duty Dodge W250 and W350 trucks from 1991 to 1993, offering significant improvements in durability, power handling, and operational efficiency. This comprehensive overhaul features all new bushings, a redesigned valve body, and upgraded internal components that enhance transmission performance and lifespan. The replacement of stock thrust washers with roller Torrington bearings reduces friction and saves governor solenoids, contributing to smoother operation and extended component life. Drilled intermediate shafts improve lubrication flow, while the modified manual valve ensures proper lubrication across all gear positions. The transmission is reinforced with increased clutch apply pressures—up to 80% higher than stock—allowing it to handle up to 300% more power and torque, making it ideal for towing, heavy hauling, or high-performance applications. Enhanced internal components, including heavy-duty clutches with up to 25% more material, machined pressure plates, billet components, and a fully rollerized geartrain, ensure increased durability and reliability under severe operational conditions. The transmission pan, made from lightweight aluminum, reduces case flex, minimizes internal oil leakage, and features heat-dissipating fins to maintain optimal operating temperatures. Additional features include a magnetic drain plug, extra oil capacity, and a BD auxiliary full flow filter kit for superior protection. The upgraded governor pressure transducer and solenoid provide more precise control, while the revised oil circuits improve lubrication and cooling. Each unit is dyno tested to ensure quality and performance, backed by a 36-month/150,000-mile limited warranty. This heavy-duty transmission upgrade is a reliable choice for fleet operators and enthusiasts seeking longevity and high performance in demanding applications.
Features:
- Heavy-duty internal components and increased clutch material for superior power handling
