Ford E4OD 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 Baumannator TCS transmission control system provides complete tunability for the E4OD transmission and allows it to be retrofitted to earlier vehicles. For more details, please see the Performance Guide in our Tech Section..
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.
ReCal Pro™ E4OD Valve Body Recalibration Kit
Our valve body recalibration system for the E4OD transmission brings the quality and performance associated with the Baumann name to this largely unappreciated light truck transmission. Most recently noted for its use in the F-150 Lightning truck, the E4OD has been around since 1989 and has been "perfected" during the last few model years. E4OD's can be identified in 1989-1993 E and F-Series trucks and full-size Broncos by the presence of an "overdrive cancel switch" located on either the instrument panel or the shift lever. 1994 and later vehicles are not as easy to identify because they may use the AOD-E/4R70W transmission which also uses an overdrive cancel switch. Please refer to the E4OD chapter of our Performance Guide for the specifics of transmission identification.
Our ReCal Pro™ E4OD valve body kit eliminates the mushy shifts that have earmarked this transmission since its introduction while greatly improving durability. Shift quality is even more adjustable than our famous AOD valve body recalibration kit, with five shift firmness levels available for each shift. Milder settings can be used to improve transmission life in tow vehicles without sacrificing shift quality or creating harshness, while maximum settings provide off-road and racing vehicles with traditional neck-snapping, tire-chirping shifts if so desired.
Factory E4OD valve body calibrations do not leave much room for additional torque input, so any engine modifications performed should be accompanied by appropriate transmission improvements. Valve body modifications are the only way to improve full-throttle shift firmness in the E4OD transmission, therefore the ReCal Pro™ E4OD valve body kit should be your first step when seeking to improve transmission performance in your truck. In most cases, no other modifications are necessary (other than possibly an auxiliary transmission cooler). To control shift points and fine-tune part-throttle shift firmness, our Baumannator TCS™ electronic control system for the E4OD transmission will be necessary (see below).
