Before the "Windsor V-8" pattern AOD-E was introduced in 1994, the AOD was the only choice for a compact* automatic overdrive transmission for 5.0/5.8L V-8 applications, such as the Mustang. The AOD has been out of production since 1993 and while this transmission could be drastically improved with well placed modifications, the AOD-E/4R70W transmissions are a much better choice if you are starting from scratch. For more details, please see our Performance Guide.
* The E4OD truck transmission,
introduced in 1989, is large and heavy, making it difficult to use in most
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 the ability to raise
WOT shift points in the AOD transmission.
This easy to install kit is the most
advanced, flexible, and reliable valve body recalibration system in the
industry. Full user programmability of shift firmness and behavior, along
with adjustable full-throttle shift points (up to 1100 RPM greater than
stock) and full-throttle overdrive capability allow the transmission to
be custom-fitted to any application. Superior shift improvement is accompanied
by a substantial increase in durability and performance (due, in part,
to our intelligent pressure control system). As featured in October 1990
Ford, January 1991 Mustang Monthly, February 1992 and July 1993
Mustangs and Fast Fords and other magazines. Installs in 3-4 hours
by removing only transmission pan and valve body. As with all of our products,
this kit includes full technical support. Complete with detailed
instruction booklet and all necessary parts.

AOD Pressure Regulator Boost Valve Kit
This high quality valve and sleeve, manufactured by Sonnax, cures many line pressure related problems in the AOD transmission. Sticking or worn boost valves are a leading cause of failures and shift complaints with the AOD transmission. Over time, the steel valve will wear into the aluminum sleeve, causing the valve to stick and leak. Since the boost valve is responsible for increasing line pressure to match engine torque, it is obvious that the condition and calibration of this valve are even more critical in performance applications. This "better than new" replacement sleeve is manufactured from wear-resistant Deltalloy 4032 and is sealed to the bore with O-rings, unlike the original equipment sleeve. We recommend replacement of this valve during the installation of our valve body kit, or especially in a high mileage transmission or during an overhaul where contaminants will have accelerated the wear of the original valve even further.
Catalog Number: BV-1
OEM AOD Transmission Filter
Replacement transmission fluid filters are available as a modestly priced option when purchasing any of our AOD valve body products. These filters are the same high quality units that Ford uses originally, and are manufactured by Sealed Power. Please specify two or four wheel drive when ordering.

Alto Direct Clutch Pack Kit
Alto's heavy-duty direct clutch pack kit is a good item to install when overhauling your AOD transmission. It will allow you to install seven or eight clutch friction plates in your stock direct clutch drum (depending on application).

OEM Quality Overhaul Kit
Our OEM quality overhaul kit contains the same parts that Ford put in the AOD originally, and is capable of handling over 400 horsepower (with appropriate input shaft). Includes everything that you will need for an overhaul (clutches, overdrive band, gaskets, seals, filter, etc.). For severe-duty applications, inquire about Raybestos Blue Plate Special® racing clutches, available as an extra-cost option.
