E4OD Major issue's
Well I have a 93 bronco with a stock motor, stock gears and 33x10.50 BFG's... On my way home for T-day I started pukin up tranny fluid like a drunk college girl... I think its probably just a seal or something on the tranny.. it actually happen once before I dropped on the tranny myself and brought it to a great shop in my town... it cost about $215 for the to pull it apart, tell me there was nothing wrong.. and put it back together I guess with new seals and the like... the question is whats in there? just seals? valves? I mean what do I need to replace to totally clean it out... is it something I can do or just drop it off with a pro?
I'm pretty good with my hands I can fix just about anything, but I don't have special tranny tools... I don't even know if I would need them... I guess I'm just dealing with the unknown... so I turn to all of you... what am I in for?
Thanks.

Your E4OD has a small temperature operating range. It won't work right too hot or too cold. I would suggest because of your tires and you probably have the 3:55 gears, put a trans cooler inline. Run the hot line to the cooler first and then to the radiator. It will keep it at a more steady temp if rigged that way.

The insides of the E40D contain the valve body, and a bunch of clutch packs, bushings/bearings, and seals. The only special tools you would probably need are a set of Snap-Ring pliers, and your common tools. Ripping into an automatic transmission is not too complicated, but it makes a huge mess and is time consuming.
Where exactly it is leaking from? If is coming out of the fill tube, I would guess it's overfilled or getting too hot.

Well I'm not sure where it was leaking out... as of right now its stopped leaking, but the temp is still climbing.. also I have a strange shifting problem... it hang going from 2 to 3rd... I'm having just alot of issue's with this tranni, now a guy at a local shop is telling me to fix the electrical shifting problem, maybe about $150 anf go from there... is the shifting module needs to be replaced its about $800 worth of work... I'm wondering if I can do it myself, and of course I'm really wondering what it would be like to change the e4od with something much cheaper and stick of course... like and M5OD, or a ZF5... something.... I need help on this one... big time.

I have 90 Bronco with the same tranny
It got to a point where it would not shift into over drive. One time driving home from mall the tranny would not shift out of first. finnally got home trying to back into driveway and it would not go into reverse.
The E4OD trans is all electronically controlled. There is a computer that will do a diagnostic check on trans and give some type of code to figure out what sensors maybe bad.
Well, since I do not now enough about trannies, I dropped it off at the shop to have it completely rebuilt, ouch, not cheap. The shop that did work on trans in January did a #!@#!poor job is pretty much what this shop said. The guy that I bought the Bronco from said he had it rebuilt while he had it.

I have an E40D in my 90 Bronco and had some leaking probs. My experience was that I had blown my front pump seal and ATF was leaking out of the opening on the bottom towards the front of the bell housing, there should be a rubber plug there. I have also experienced unusual shift patterns in auto trannies when there is dirt clogging the filter. Is your fluid and filter clean and has it been changed recently? That is all that I can suggest with my experience. About the ZF5 tranny swop, I have been looking into that as well and it does mate to the 351 and is much stronger than the M50D from what I understand, it also has around a 5:1 first gear and an overdrive. If you find out about the manual conversion let me know, there is supposed to be a shop that will do the swap for $3000 out the door in my town or so I've heard. Good luck.

A friend of mine had a 90's F-250 4X4 with the 351W and a 5-speed manual tranny. Maybe check the junkyard for one of these. I am not sure what tranny it was, but it obviously bolts to a 351!

Another approach would be to consult with the guys at Baumann Engineering (see their web site). They can fix you up with parts to modify your tranny, and they have the hardware and software to let you completely take over control of the shift program, something they call the "Baumannator".
