AOD or E40D How do you tell the difference?
Hey guys I have a 92 F-150 that was manufactured in 91. I have been told that some of the early 92's had AOD's before ford made the swap to E40D. Don't know if thats right thats just what I've been told. The reason I'm asking is because I'm thinking about a mass air conversion and it makes a big difference. Any help is appreciated.

Look at your gear selector.
P R N (D) 2 1 - E4OD (1992+ will have OD cancel switch on column shifter) (1989-1991, OD cancel switch on dash, right side of steering column)
P R N (D) D 1 - AOD
P R N D 2 1 - C6
Or you can count the pan bolts.
17 pan bolts - C6
14 pan bolts - AOD
20 pan bolts - E4OD

Easiest way is to climb under and count the pan bolts

If my AOD gives out I can rebuild it for around $600 or less

My E4OD can be a PITA at times but I will take it any day over my AOD.

The problem with the E4OD is it shifts WAY to soft! Any tranny that shifts really ssoft like that will never live long.
That's why if I have to have an auto, it MUST be a C6, I will refuse anything else! The hell with OD!

I adjusted my TV cable to hold the gear longer and shift stiffer

Benefit to the AOD is that it will bolt up to any small block ford, and Lokar sells kits to put the AOD behind a Carburated engine. (If you don't have the carb kickdown bar for the AOD)
