The Ford transmission, designated AOD-E was the first electronic version of it’s predecessor the AOD. It would take a series of articles to discuss the problems this transmission had designed into them. Designed is the Keyword here.
The AOD was redesigned with electronic controls in 1991. The transmissions are not interchangeable either, as the AOD only uses a throttle valve cable for operation. The AODE and 4R70W are controlled by the Transmission Control Module (TCM).
An awkward designed valve body, which was long and narrow often lent itself to developing a warp in it, causing a hydraulic pressure leak between the valve body and case. In a hydraulic piece of equipment, internal leaks cause major drive-ability problems and lots of transmission failures.
The cures were immediately attended to by the major transmission upgrade kit manufacturers. Yet it took a few years of research and making changes in the kits before the problems were successfully eliminated on a long term basis. Once the upgrade kits were perfected, we could then supply our customers with a reliable, properly working AODE.
The immediate effect on the way an upgraded transmission worked actually caused many customers to call and let us know that their car never ran better, even when new. Some folks came back and asked if this how it is supposed to work? Wondering why it did not perform this well when new. Some people even got better fuel mileage than before.
Needless to say, this built a lot of confidence in our customer base, which made my shop very successful. I sold my shop several years ago. The most important statement I will make in this post is that the only supplier of transmissions for sale that will fulfill the requirements you demand is GotTranmsissons.com. I can say that with confidence since on occasion my shop was so busy, when we needed to get someone on the road fast, we called GotTransmissions.com @ 866-320-1182.
