Hi, I have searched hi and low for this info and cannot find a clear answer.

I have a 1992 F150 2WD 5.8 E4OD. Trans is original at 154,xxx and finally gave up.

I bought an E4OD from a 1995 F150 that was bought as a Ford Renewal about 2 years ago and has about 15k on it. Trans looks good to go except for trans fluid that has leaked into the solenoid block connector.

I have seen info saying you just have to "move a couple of wires around" to work with the 95-up solenoid, but I dont know which wires those are.

So I am going to replace the solenoid block, but my question is: should or can I buy the early solenoid block 89-94 or the 1995-up solenoid block?

Again, my truck is a 92 the trans is a 95.

Thanks!

 

I do know that on the e series vans the e4od out of the 94 would not work right in the 95 -the shift solenoids were different-maybe you can just swap the one out of yours-I had to replace one my self-ain't too hard-give that a try

 

Maybe, that's the question. Can you put an 89-94 solenoid block in a 95-up E4OD? I would rather put in the later "improved" solenoid block but I do not know if it will work and I do know that the connectors/pin positions are different.

I am worried that if I just try it, I'll do some damage to a perfectly good and expensive transmission.

Anybody know for sure?

 

if my memory serves me right the newer packs are missing a relay that is now in the computer-just had this problem about 2 years ago-had a 94 shift pack out of a burned up trans but it would not work of course-the new one I got from ford was around $300-was still cheaper than a rebuild-and 90% of the time they don't change out the shift packs anyway-darned crooks! have ya posted anything on the transmission thread-you might get some answers there ? numberdummy-Subford or conanski would probably know-if ya see where they post send them a private message one of them can tell ya for sure-or countless others-a good group of guys and great info available on here

 

No I haven't posted in the transmission thread, I will give that a try as well. I think your right though, I have seen some references that the 95 and up computers are different.

 

if my memory serves me right it is different the computer that is and so are the packs-changing out your pack for the newer one should not hurt the trans-at least I don't see why maybe try the trans thread and see what some of those guys say
good luck my friend-keep us informed how it works out always good to hear the end result it might help someone else down the road

 

Ok, I got an answer over in the Transmission section!

Jk080 posted up an old service bulletin that basically said:

The 89-94 solenoid block must be used on an 89-94 truck because there are ECM diodes contained within the block that protect the computer.

On 95-up trucks those diodes are contained in the computer itself and NOT in the solenoid block.

It even says on the bulletin the two solenoid bodies are not interchangeable.

So to everyone else that I've talked to other sites, you are wrong! Do not try and re-pin or replace the solenoid connector on your 89-94 F-series or Bronco to try and make it work with a 95-up solenoid block it won't work and it sounds like you may even damage the trucks computer.

Now, if this is common knowledge I apologize, but I could not find any resource anywhere that stated this.

I am really glad I checked on this site before I changed out transmissions!

You will have to use the 89-94 block.

The plug is different and wouldn't plug up anyways, I know you can use a 95 and later solenoid block on a 89-94 trans and install it in a 95 and later truck, I am not positive you can use a late trans in a early truck with a early block, but I would think it would work with no problems.

This is a old bulletin, 13 years, so the new solenoid blocks they are referring too, are not that new anymore....."

 

so basicly you can switch the shift packs from the older one to the newer one and be okay?I remembered something about the computer-being different from 94 to 95 and the packs too-the trans itself minus the electric shift packs should be darned near identical
