Probably one of the most popular transmission exchanges that are being performed on '60s and '70s Ford cars and trucks involves using the Ford AOD or automatic overdrive. The AOD can be a relatively easy transmission to transplant and the additional 4th-gear overdrive can give you added fuel savings, especially in cars and trucks using taller rear axle ratios. Because Ford used these transmissions in so many production vehicles, the Ford AOD is relatively easy to locate at a used parts yard and can be purchased for a reasonable price. The Ford AOD does not need a computer to function properly either. The throttle valve function is mechanically activated and the torque converter lock-up function was contained entirely within the transmission case. Ford later used this transmission as a basis for their newer overdrive transmissions, the electronic overdriven AOD-E, which was used beginning in and in the 4R70W which was used on '99 and up production cars and trucks. Using an AOD transmission will effectively lower a 3.

Transmission All geared up? Talk trans here. The good, the bad and the ugly. AOD transmission ID. Thread Tools. I looking for info on how to decode a transmission model tag. I'm rebuilding an AOD, and found a tag on the extension housing but can't decipher what it means. I concerned becasue the model had serious defects so I don't want to put money inot a possibly bad tranny. Since I salvaged this transmission I don't have a matching VIN code or any vehicle facts that would match. View Public Profile. Send a private message to classiccruise.

They further modify the transmission by removing the Fourth Overdrive gear and replacing many of the components with lightweight pieces.

The oil crisis of was a jarring reality for many American motorists as fuel became more expensive than it used to be. The only way out of this quandary was to use automobiles that consume less fuel without compromising power. By the time another oil crisis came on the scene within that decade, i. This is where the Ford AOD transmission came into the picture. Chrysler and General Motors soon followed suit. General Motors developed the into a R with overdrive while Chrysler added more overdrive units to the existing 3-speed automatics: the and The only difference is the direct overdrive lockup — to do away with wasteful slippage — and add-on hydro-mechanicals. The automatic overdrive came in a fresh-cast aluminum case with an overdrive unit as well as a trustworthy planetary gearset. However, it notably incorporated the existing tried-and-tested Ravigneaux geartrain components, conveniently borrowed from the BorgWarner FMX parts bin, i.

Ford also attained seamless shifting by slipping the converter clutch, which cycles the converter in and out of lockup. All rights reserved. Converting to an AOD transmission can be cost effective too, in terms of gas savings you should realize from the extra overdrive gear. What's New? Buy the full book here! Be sure the kickdown lever and rod or cable comes with the transmission because these are disconnected during disassembly and you will be hunting around for them later when installation begins. The Ravigneaux gearset is the workhorse that does the work of two planetaries. Log in. Just like with our old parts, the F3 is the first year for that model of AOD, not the actual year of manufacture. Most of the other applications will be longer and require drive shaft shortening.

Seeing as we don't know a heck of a lot about Ford automatics, we abducted a variety of transmission experts and interrogated them for the following information.

They also offer a matching direct drum and torque converter. Since I salvaged this transmission I don't have a matching VIN code or any vehicle facts that would match. Instead, this function is outside the case. It took quite a few years for Ford to get the AOD dialed in to be a solid performer, however, and this occurred with help from the aftermarket and off-road racers. This stamped assembly, known as the center support, supports the geartrain. Although there were virtually no engineering changes to this pump during its production life, there are variations in this casting number, depending upon when it was cast. Photo: Barrett-Jackson. The manual valve detent is a hollow shaft with the throttle valve shaft inside. AOD ID?? Units for and up were for fuel-injected cars and will have the TV cable activation. Ultimately, Ford eliminated the accumulator in production, which is why some AOD cores are not so equipped. It works hand in hand with the PCM to unify engine and transmission cohesiveness.
