Strengths of the E4OD and 4R100 transmissions The COMPUSHIFT 4R100 / E4OD transmission controller allows you to customize a shift strategy that works best to leverage the gear ratios of this transmission. The E4OD and 4R100 transmission have the exact same gear ratios, with the 4th gear being the overdrive gear. It was more durable, could handle a higher torque rating, and solved some of the electronic issues that affected the E4OD transmission. In 1999, the 4R100 transmission was introduced as the successor to the E4OD transmission. Shifts are done electronically with solenoids and fluid pressure control systems which engage the optimum gear based on the input from a transmission controller. The newly introduced electronic shift controls include the use of a standalone transmission control module. A lower engine speed also results in less engine wear over time and a quieter drive on the highway. It improves overall performance and leads to better fuel economy. This is because the transmission ratio makes the output shaft spin faster than the input shaft from the engine. The extra overdrive gear allows the vehicle to achieve a higher cruising speed with a lower engine speed. The advantages to these updates were numerous. The E4OD transmission was introduced in 1989 and was based on the core components from the hugely popular Ford C6 transmission, which had started to feature an overdrive gearset and electronic shift controls. They are both very similar in design with the 4R100 transmission being the newer and improved version of the E4OD transmission.

The transmission was designed and built by Ford to fit a variety of their heavy-duty diesel vehicles such as the popular F-series trucks.īoth these transmissions are electronically controlled 4-speed automatic overdrive transmissions so are suitable for use with a 4R100 / E4OD transmission controller. IntroductionĪ Ford 4R100 / E4OD transmission controller can control this heavy duty automatic transmission made by the Ford Motor Company. Using the COMPUSHIFT 4R100 / E4OD Transmission Controller with the Ford 4R100 / E4OD Transmission.
