AOD - AODE - 4R70 - 4R75 Performance Converters

AOD-E / 4R70W / 4R75 Performance Torque Converters
Modern Ford overdrive strength, built in Dearborn.

Dearborn Precision Performance Parts builds high-performance stall converters for the AOD-E, 4R70W, and 4R75 transmissions. These electronically controlled overdrive units are popular in later Mustangs, trucks, and performance builds that need both street manners and the ability to handle real power.

Every unit is engineered and assembled in Dearborn with thorough TIG-welding on the impeller and turbine, heavy-duty sprags, USA-made bearings, high-energy clutch materials, and CNC-machined components. The result is consistent flash stall, strong power transfer, and the durability these applications demand.

What you’ll find here:

  • Street and strip stall ranges (3000–4000+ RPM options)
  • Anti-balloon designs with fully welded construction and bearings
  • Converters built for both daily driving and higher-power applications
  • Precision balanced and tested units ready for installation

Whether you’re running a later-model Mustang, a performance truck, or any other AOD-E / 4R70 / 4R75-backed build, these converters are made in the 313 to dominate Detroit streets and win out at Milan Dragway.
