BD Diesel USA is a performance-oriented company specializing in high-quality diesel and heavy-duty truck components and upgrades. Their products are engineered to handle high pressure, high temperature, high load, and extended operation, not just occasional use. With years in the field (including intensive hours of idling, towing, and heavy usage), the BD Diesel's engineering and R&D is informed by real use cases.
This Tranmission is designed to handle the output of the stock engine but with increased durability from the upgraded snap ring, pressure regulator valve, and aluminum plugs.
The common issues, including the run-away reverse pressure, gear slips, and case lug blow out are solved with these upgrades.
The deep sump pan allows for more fluid capacity and better cooling. Great for those with stock trucks looking to replace their Tranmission.
