BD Diesel Performance Automatic Transmissions

BD Diesel Performance automatic transmissions are designed to transfer the power from high-torque modified diesel engines. They feature redesigned clutch packs with 50 percent more holding surface, steel 6-pin planetary gear carriers, and new lube ports added for high-load areas. Shift strategies and pressure circuits are also modified to handle the high-torque applications. BD Diesel transmissions are not rebuilt factory transmissions--they are custom-tailored to work with your modified truck.

ATS Diesel Performance Stage 1 Transmission Packages

ATS Diesel Performance Stage 1 transmission packages eliminate the factory weaknesses and design flaws.

Plus, the units are fitted with ATS deep pans for increased volume, cooling capacity, and strength over stock. They will perform well in daily use and yet handle extreme power and heavy loads.
