[lizardj1986]

I HAVE A E4OD TRANNY ON MY 99 F250. I PRESS THE BUTTON ON THE SHIFTER AND NOTHING. BEFORE IT WOULD ONLY WORK WHEN PARKED AND AS I WOULD PUT IT ON DRIVE THE LIGHT WOULD GO OFF. NOW IT JUST DONT WORK WIRING INSIDE LOOKS GOOD AND CONNECTOR OUTSIDE LOOKS GOOD. FUSE IS ALSO GOOD. DEALER SAID IT COULD BE THE PCM. I DONT NKOW WHAT TO DO PLEASE HELP

That trans should be a 4r100 How does it shift.

I have an E4OD in my 97 and when the trans was rebuilt they said that the snapring came off of the OD assembly. Turns out this is a common problem and there is an upgraded snap ring.
I got to watch them put the new on on when they assembled my tranny, no way a new one would come off.
But I agree with Powerplant, Are you sure it is an E4OD? and Not the 4R100.

I BELIEVE SO. AT LEAST THATS WHAT THE ORILLES PEOPLE SAID WHEN I GOT A NEW FILTER FOR IT. IT SHIFTS KINDA HARD WHEN THE OIL IS COLD. BUT REALLY SMOOTH THE OIL HOT. WHAT COULD CUASE THE O/D NOT TURNING OFF??

It maybe the wires in the steering column they can break and short out. Witch could cause your problem. I have heard about it a couple times on here. I would check that out. I would also take it to a trans shop and have them run a diagnostic test on it. If you have any transmission trouble codes a regular code scanner will not retrieve them. I rather pay 100 dollars to have it checked out by a trans shop then pay 1800 for a rebuild.

Well, I know that when you do a rebuild, alot of the parts can be the same. Example: my shift kit was for both E4)D and 4R100.
A good trans shop can tell you at a glance. There are other way's but they slipped my mind(had to learn something new) I'm sure a tech will pick up on this.

But keep in mind, There are alot of things that it could be, nothing will tell you like a good diagnostic.

Scanning may help you find the problem. My E4OD didn't have any codes at all, But when It was disassembled, there was the snapring.

Of course, Scanning is ALWAYS the place to start. As for you fixing it, go for it. Transmitions are the only thing I wont do. I'll do everything else.
I watched the guy rebuild mine, it didn't look that hard. Just a crap load of parts.

I know if you do a rebuild you will want a press. other then that I have no Idea on special tools required.

Lizard I am not going to tell you what to do. But unless you have torn down one of these transmissions. Save yourself the head ache. Let a tech that does it everyday for a living do it for you. Or find someone that will help you do it that has done it. Because if you do rebuild it, and decide to put a shift kit in it to raise line pressure. Well if you put the wrong spring in the wrong spot. Or if you drill a hole in the wrong spot on the valvebody your not going to know it till you get the truck all back together.

I am telling you this from experince. I have rebuilt turbo 350's and turbo 400's, but when I attempted to rebuild the 4R100 in my truck. I ended up going to a trans shop 6 months later.

SO YOU TOO HAVE A E4OD THEN?? WHY DID THIS GUYS ACT ALL WIERD WHEN I TOLD THEM THAT I HAD ONE??
