Need help
I have a 82 f-150 4X4 351w 3 speed auto trans.
I need to know what I need to put a 4 speed auto in it.
What other years I can remove trans and flywheel from. No electric.
Bolt up and go. Thank you

The AOD is non-electric, and was found behind the 351w in some applications. Not sure about 4x4. It was a troublesome box in it's early days and Ford improved it over time. '88 to '93 from a truck or V8 are the preferred starting points.
What are you trying to accomplish? If you are going for gas mileage, do the math. You will have to drive that thing repair free for 10 years* to pay back the cost of an AOD and all the fixin's.
*WAG internet estimate, ymmv

Two more options:
1) The electronic E4OD with external control (MSD makes a standalone controller). https://www.summitracing.com/parts/m...FQ4GhgodamYMQg
2) A Gear Vendors overdrive, which bolts to the back of your current transfer case. https://www.gearvendors.com/4x4.html
Neither option is cheap.

I would recommend the AOD too, if you can afford it, save up for one from Monster Trans, like this:
AOD Transmission Remanufactured Heavy Duty Performance 4x4
That way, you won't be tearing out a junkyard trans in a couple months. you'll need the flexplate from a 79-91 Crown Vic w/351/AOD

So, if I were to go to the junkyard or keep my eye open far an AOD, What year of 4X4 should it be out of?

They started using them in 4x4 f150's starting about 1985. But you will only find them behind 302's those years, probably most years up to 96.

You can see what years and engines had what auto transmissions here: Automatic Transmissions - ???Gary's Garagemahal. And Ford called the AOD an AOT.

No not electric. It has a valve inside the trans that sends fluid up through the hollow input shaft and that locks up the convertor. But that hollow shaft is also a weak point if you want to pound on it. It you drive normally it would probably hold up ok, I would run a cooler on it.

I don't know anything about AOD transmissions - but it sounds like some (maybe later models) may have had an "electrical component" to them - as there is an AOD transmission here that has "an electric O/D delete" AOD - Broader Performance
But I'm not sure what that is. It is described as an electric solenoid added to control OD on/off. Maybe it's just a mod that "Broader makes/adds" for performance reasons.
A call to Broader Performance can probably answer a bunch of your questions (even if you don't buy from them).
