ok there is a bunch of parts out there and i dont want to buy the wrong one.. i have a 2000 ford screw 4.6l and i dont know the diffrence between the two names.. i know that AODE stands for "Automatic Overdrive and Electronic" but what is the 4r70w?? is it the same thing they just leave the AODE part of the name out or what.. sry if this is a stupid question its just been bugging me.. on my tranny it says 4R70W ... it doesnt say the AODE or AOD anywhere and im guessing i just have the 4R70W .. soo pls get back to me
First there was the AOD. It was an overdrive transmission that wasn't electronic.
Then came the AODE, that was an overdrive transmission that had the same gearset as the AOD. The diameter of the yoke you need for this transmission is different than the 4R70W and your computer would spit if you put one in where is expected to see the other gear ratios of the 4R70W. There are 2 different lengths of this transmission.
Next is the 4r70w. It is very similar to the AODE. Basically what they did was take the AODE and install a wide ratio gearset. Hence the W for wide ratio on the end of the name of the transmission. It has a larger bore on the tailshaft housing so it takes a larger diameter yoke. There are 2 different lengths of this transmission and a 4x4 version. Sometime in late 2002 or early 2003 they removed the drive gears from the output shaft on the short tailshaft version of these transmissions.
Next were the 4R70E and 4R75W and E. Same basic transmission again. There were changed made that made for yet again a better transmission. The pump, intermediate piston, forward drum, sun shell, ring gear and a few bearings are different internally. Most of these transmissions have an added sensor to measure the speed of the forward drum and the output shaft sensor has a different means of calculatiing. They aren't a direct swap into a vehicle that has a 4R70W.
Its early and I may have left some stuff out. I kept remembering things while I was typing. I think I covered most of the differences though. I may have not mentioned all of the versions of them though.
Yup, there are a lot of versions of "almost the same thing" here.
If you are talking about a newer vehicle then you need to get one with the small diameter locator pins for that. It has to be for a 96 or newer 4R70W. The older vehicles ahd a larger diameter locator pin and you can't cram it into the hole without drilling on your transmission or having the pins machined.
I don't like either route. I think the newer stuff is just better.
In short, it depends on who is making the valve body. I could tell you more if I knew that.
well the year of the truck is 2000.. on the tranny tself it says 4R70W in my door jam it says "U" which is in translation "4R70W" so i know i have a 4R70W.. now the valve body ii just picked up iis called a "AODE/4R70W" and everyone is telling me and swearing up and down that the AODE is virtually the same tranny as the 4R70W.. .. so agian would this valve body work?
thanks for allll the responses it is extreamly helpfull!!!
Well if you have the valve body then you can measure the diameter of the 2 pins that stick out through it on the side that mates to the transmission case. If they measure around .177 then yes. If they are in the range of .236, then it won't go in without changing something.
Or if you don't want to get that fancy, look to see if there are 2 bolt heads on what would be the bottom side of the valve body that are larger than the rest of the bolts there. If so then that is actually for an AODE and it won't fit straight in.
I see that 'AODE being the same as a 4R' thing a lot too and it's just an ignorant statement. They are not virtually the same. They are very similar but there are several very important differences.
ok so there should be two bolt heads that are bigger than the rest and if that is so.. then it wont fit...
on the face of the valve body that is set agianst the tranny there are two rods that from my understanding make it fit straight in
when i got the valve body it had two bolts that were loose and were not connected to anything.. so im guessing that they screw into the tranny and im also guessing that they are the two that will tell me if it will fit or not.. thank you soo much ...
Another fact is that the AODE was never used in a F-150, just in cars.
AOD from '85-'93 with the 302
4R70w in '94-'96 with the 302 (E4OD optional and more common)
4R70w in '97-'03 with the 4.6L and 4.2L
4R75e in '04+

I'm glad you said that I have said it a million times and figured no one paid attention. AODE transmissions were basically in crown vics, grand marquis, mustangs and town cars. Even the vans got 4r70w's.
