E4od And Aod

[404PageNotFound]

i'm looking at a 91 Bronco XLT on ebay with a 351 in it. and i'm wondring if theres a way to tell if it's an AOD or an E4OD?

i'd rather not find out it's an AOD by dismantling the truck

The E4DO has the push button overdrive on the dash & the AOD has the overdrive on the shifter.

A 1991 should have the E4OD. If you have a pic of the tranny, the pan on the AOD is square, while the E4OD is notched on one corner just like the C-6.

Here is a site that has all the ford automatic transmissions.

look at the top of the engine on the thottle body. the e4od doesn't have a kick down linkage its done by the computer.

whick tranny is the better

I think the E4OD is better than the AOD, but the ealy version of the E4od up to 95/96 were not as strong as the later one.

The probability of the e40d being better is not very good. The aod is lighter and when built right (yes it has to be built) will be strong enough for your needs. I am not a big fan of the e40d because when someting goes wrong with them it is usually big. As far as the aod...they just wear out. Rebuild them with a j-mod and you are in business. I would have to check to see what other upgrades you could do. I know the birds didnt have the low 1-2 in them until they went to an aode, not sure about the pickups. As far as the push button, if it is an aod there is not button. They did not get one till they turned into the aode. One more thing you can do is look at the tranny pan of a bird, moostang, crown vic, or ANY rear drive ford car. They all had aod, aode, or 4r70w trannys.

Is it safe to assume that my '88 XLT with a 3 speed auto is a C6?

Yes. If you do not have overdrive (OD) in the 88 Bronco, the 3-speed auto is a C-6. The door jamb code is a "K", and the bottom pan is "L"-shaped or notched in one corner, with 14 bolts. A very good tranny, IMHO.

AOD has 14 pan bolts

E4OD has 20 pan bolts

The quickest and easiest way to tell is this the E4OD is electronically controlled the Aod shifts with a cable that runs up to the throttle body and moves with the throttle to control line pressures . If your truck has an E4OD there will be an overdrive cancel button either on the dash to the right of the guages (1988-1991) or on the end of the shift lever on the column (1992-1996) The Aod is not electronically controlled so you will only see a overdrive/2/1 on the guage face there will be no overdrive cancel . /emoticons/[email protected] 2x" width="20" height="20" />
