Ok so im new to the forum and i have a quick question about my truck..
I purchased a 1991 Ford f250 for $900 from a guy in my neighborhood who swapped a 1988 Lincoln 5.0 motor into it an he told me the tranny was shot because it wouldnt shift. So.. i pulled the tranny an had it all re-built by a local guy here in Des Moines an put the tranny back in an it still dosent shift. Im no too familiar with the tranny's in these trucks but i guess its the all electronic one with no TV cable on it. I guess my question is what computer do i need to run this transmission?? Ive swapped in about 4-5 different ones and none of them seem to make it shift??

Any help is much appriciated

 

it sounds like it has a E4OD transmission in it. yes you do need a correct matching computer to run it, so you need to find a 5.0/E4OD truck and get the computer and swap it in. otherwise it will not shift. any other computer wont work.

 

Waht years have this E4OD transmission??

 

eh im not completely sure, there were a few years where the AOD-E was most common behind a 302 so its hard to say, maybe someone will come along that knows for sure

 

ok thanks for your input

 

well before you get into all that. we need to figure out what trans you have, is it a 3 speed with a 4th overdrive? is there a cancel button on the end of the shifter or on the dash.

 

im not quite sure... i has the cancel button on the dash

 

does it matter if the computer comes from a f150 or a f250 just as long as it has the E4OD trany??

 

just as long as it matches the engine and trany, i can say that i have an e4od and 5.0 in my 94. maybe try calling some junkyards

 

ive purchased a few from various junk yards.. how can i tell what the computer goes to?? is there a certain number i need to look for on the computer??

 

take a look on here... Ford Fuel Injection EEC Program Codes it looks like it needs to be code E1A1 computer for a 5.0 Speed Density E4OD.

 

if subford were here he could tell you right off. but yes each computer has a code, that ID's it to the engine and trans

 

ok here is one of the computers the junk yard sold me that they said was the right one:

White sticker:

EEC-IV EFI-SD47B A1C
F1TF-12A650-TA G
61ES57BM05 24179-114 4C21

 

I looked on there and counldnt find my computer on there anywhere

 

is there any way you could take a picture of the sticker. its hard to make out where the certain numbers go...
