The BD Diesel 95-97 Ford E4OD Transmission Stage 4 Package is a comprehensive overhaul designed to significantly enhance the durability and performance of your heavy-duty truck’s drivetrain. This high-performance transmission upgrade features a machined center support, intermediate piston, low/reverse pressure plate, and rear ring gear hub, all crafted for precise fit and maximum strength. The inclusion of added lubrication circuits to the output and intermediate shafts, along with the replacement of all aluminum planetaries with steel components, ensures improved internal lubrication, increased torque capacity, and long-term reliability under demanding towing and hauling conditions. The full shift kit with line mod valve increases line pressure, providing faster, more positive shifts, while the reprogrammed accumulator body enhances control, response, and overall drivability.
This upgrade handles up to 300% more power and torque than stock units, thanks to extra clutch material, tighter clutch packs for quicker shifts, and a fully rollerized geartrain. The package includes a BD rigid aluminum heavy-duty transmission pan, which reduces case flex, improves oil retention, and features heat-dissipating fins that help maintain optimal operating temperatures during heavy-duty use. Additional features such as the auxiliary full flow filter kit for 1990-2003 models, high-temperature resistant solenoid wiring, and a machined front pump contribute to superior internal lubrication, heat management, and durability. These enhancements collectively promote a more efficient operation, better fuel economy, and increased longevity of your drivetrain, especially under severe towing, street, and towing applications.
Each transmission is dyno tested to ensure quality and performance consistency. The package also includes upgraded supports, sprags, sure-loc snap rings, and a torque converter with machined positions for optimal engagement. Designed for heavy-duty applications, this transmission upgrade is ideal for fleet operators and enthusiasts seeking a robust, reliable, and high-capacity drivetrain solution that handles increased power levels while maintaining smooth, responsive shifts.
