4L60E Rear Wheel Drive
O.D. Transmission

This particular transmission fits many GM rear wheel drive O.D. transmission models, including the popular C/K Pick-ups. It was originally used in non-electronic form in the early 1980Õs by General Motors. Hughes Performance has continued to improve this unit both in durability and technology. All internal parts are carefully inspected and many of the original equipment pieces are replaced with Hughes High Performance components. We replace OEM clutch plates with our special high-coefficient one-sided frictions* for longer life and greater reliability. Kevlar bands have been installed in our transmissions for over 15 years in shifting applications. We co-developed with Borg Warner our "High-Static Hold" material for increased holding power, especially in racing applications, for all brake band applications. All lubrication and valve body circuits are carefully inspected and modified for cooler and quicker operation. We have manufactured countless numbers of these transmissions for a wide variance of vehicles and have earned an enviable reputation from racing to towing and all types of street performance, hot rods, and custom applications. Call today for details regarding your specific application.

A727 Torqueflite Transmissions

The A727 Torqueflite: the respected workhorse of Chrysler automatic transmissions. Once Chrysler engineers added an overdrive assembly and updated the unit, it became a 4 speed overdrive known as the A518. Since its introduction in 1990, it has undergone multiple updates. Our in-house modifications, along with the popularity of the fresh design of the new Dodge pickup, make this unit a must-have. Before beginning the rebuild, each unit is closely inspected for abnormal wear. Many components are automatically replaced, even if normally passed over by other manufacturers; all friction material is upgraded, lube circuits are modified, and the valve body is re-worked to achieve more positive shifts and better durability. This is the most outstanding version of the A518 available today. Additionally, Hughes has a newly designed triple-disc H.D. Billet cover tow converter for the enhanced Cummins Diesel applications Ð please call today for more information.

4 Speed Electronic Overdrive Transmission

The E40D/4R100, an electronically controlled transmission using the latest technology, is used in all 1989-on Super Duty Ford trucks. Hughes Performance has extensively modified the lubrication circuits, valve body programming, and friction materials resulting in a superior unit. In addition to electronic updates, we use special custom hardened core clutch plates in the forward clutch to prevent failure. To prevent premature failure with the torque converter clutch, we utilize a new heavy duty lockup piston. The Hughes remanufactured assembly for this application is simply the very best available in the market. Call our experts today.
