What is the 4R70W Transmission?

Ford started using the 4R70W transmission in 1993 as a modified version of the AOD-E with automatic overdrive. The transmission has higher gear ratios than previous models, which provides better acceleration, particularly at take-off. The rear-wheel-drive unit has four gears that include first, second, third, and overdrive, as well as reverse. Ford used this particular transmission in many of its popular models, such as the Lincoln Town Car, Mustang, Expedition, Thunderbird, and F-series pickup trucks, among others. The transmission is known as reliable. At GearStar, we provide a performance transmission to replace this popular model.
