Ford E4OD / 4R100 Transmission Performance Products

The E4OD light-truck transmission was introduced in 1989 as Ford's first fully electronic transmission. While slow to gain acceptance at first, many improvements throughout the years have yielded a strong and reliable transmission. The large size of the E4OD makes it difficult to fit into regular passenger cars, limiting it mostly to truck or big-block swaps. The E4OD is the only automatic overdrive transmission that will mate with Ford big block (385-series) engines.

Most famous for its use in the F150 Lightning, the E4OD is a good choice for heavy-duty and big-block retrofit applications. Our US Shift Quick 4 TCS provides complete tunability for the E4OD transmission and allows it to be retrofitted to earlier vehicles. For more details, please see our Technical Guide.

A Note About Valve Body Kits

When installing one of our valve body systems, you may notice that our approach to shift improvement is radically different from that of our peers. Our "systems approach" to valve body recalibration allows you to tailor each and every shift characteristic to your personal preference and vehicle application in much the same manner as the factory engineers did when they designed your vehicle. You will not find any "mystery parts" in our systems because the function of every piece is explained as it is installed and no "fluff parts" are included. (We would rather spend five dollars on a functional component than ten cents on a perceived value-enhancing placebo such as an unnecessary spring or ball). Our instruction manuals are by far the most comprehensive in the industry, designed with the novice in mind, and we have many industry "exclusives" such as our five shift firmness level settings for the E4OD transmission.
