The Ford Transmission Model E4OD Ford was introduced in 1989 as Ford's first fully electronic overdrive transmission. The E40D later became called the Transmission Model 4R100. The E40D and 4R100 is in all Ford commercial series trucks. These Overdrive Transmissions are Fords work-horses.

About "The Cure":
The Cure was developed by a Ford Truck Enthusiast who realized there was a big problem with the E40D and 4R100 transmissions which Ford and the aftermarket world did not address.
Over the years the inventor was a Performance enthusiast who invented, built and used his products in real world applications. He was an avid motorsport racer, builder, and inventor of one off specialty items in the world of motor sports.
The inventor owned many Ford trucks and then custom built the trucks, and drive trains for better performance, life, and fuel efficiency. the inventor of "The Cure" was struck down by cancer which left the inventor with time to think about the problem from a different perspective and because he could no longer work physically, he had time to develop the cure.
By looking at this web site and your purchase of "The Cure", your doing more then helping yourself. With your support purchase, you are contributing to the the financial survival of cancer victims. Each unit is hand built by people who have cancer and are undergoing a very difficult time in their lives and can no longer work in fields that previously supported their families.
