And here I am haha.

In 1995 the E4OD was updated mechanically and electronically.

The trouble with the earlier units were minimal, but consistant. Ford's original plan was to make this transmission a smooth shifting unit. And that's where the problems started. The smoother the shift, the more wear on the internal clutches. After about 100,000 miles or so, they would start going out. Another problem was the torque converter. I would lock up too early. Once it got into 2nd gear, the torque converter would lock up.

In 95 Ford updated the units mechanically, like stated earlier. I can't remember exactly what they did, but I think they put a few more overdrive clutches in it and what not.

Electronically, the torque converter in 1995's and later lock up after it goes into 3rd gear. It will lockup in 2nd gear, but only if you have it to the floor and you're above 35 MPH. The computer also increased the line pressure to make the shifts firmer, allowing for less slippage than before, thus making the clutches and transmission last longer.


Please post back and let me know what setup you have. As in what year of truck you have, what engine, and whether or not you have Mass Air Flow or not. Depending on what you have, we might be able to set you up with a decent setup by using parts from different years.

I have a 94 f250 w/ an e40d. I installed the sonnax
valve kit and magnafine inline filter
I'm a happy camper. It shifts solid now and I think I've saved my tranny. 73,000 miles on it when I bought it. It was used exclusively to haul a 34 ft 5th wheel, otherwise it sat.

Like Handyman said the tc doesn't lock up in 2nd unless your in a hard pull or heavy accelleration. Sonnax has other valves to change that if you want. I elected to go with the tricumulator valve change only.

Is there a way to make my transmission stay in a gear by installing a momentary pushbutton somewhere? It would be nice to be able to make my transmission stay in overdrive when I am approaching a hill where it wants to downshift when I know it has plenty of power if it would just let me step on the gas harder without downshifting.

I'm sure there's a way, but I wouldn't mess with it. The transmission knows when it needs to downshift, so I'd let it do it.

I have no doubt that the Ford engineers made the transmissions to work a certain way for a reason, but my truck (1995 F-250 PSD) unloaded definately does not need to shift down on certain medium size hills when I am going 45mph. I know it has plenty of power to get up the hill if it would just let me shift. Isn't it worse for the transmission to downshift and then upshift a few seconds later than to put a little extra strain on the engine? I'm not sure, just asking

Well shifting causes heat, and heat causes the fluid to go bad quicker, which in turn could toast the tranny. But once every 5 miles isn't going to hurt anything.

I think these trucks are made to go into OD around 40-45 anyways. Once they drop below 40 or 45 they are supposed to go into 3rd.

My E4OD goes into OD at 37 MPH when slightly accelerating.

Gearing/tires/etc will affect otherwise.

It's nice because around town I can shift into OD and drop the RPM's down.

Just a random FYI from my experience.

I wonder if the 460 or 4.10's have different shift points. I know my 95 with the 351 and 3.55 gearing is different. The torque converter locks up at around 35-38 MPH and it won't go into overdrive unless it is above 40 or 41 MPH.

Hman, I have a 92 305 E4OD with 150,000 miles. I wanted to convert to mass air flow intake, but I noticed it said for AOD only. Do you know why? And is there a way to convert while keeping my E4OD? Thanks.

What engine do you have fordman? I think it is possible to do so, but if you have a 351, you will have to obtain a 96 computer that controlled the 351's MAF. The problem there is, the 96 changed over to OBDII diagnostics, which turns into a WHOLE other nightmare.

I think it's possible to get a Mustang computer to work with our trucks if we convert to MAF, but I'm not sure. Someone else will have to chime in on that one.

The E4OD tranny is a picky one. If it was setup for speed density, then thats the only way it will work. If you pull the vaccuum line or the plug off of the MAP sensor and drive the truck, the transmission will shift harder than hell. Reason being, the computer isnt getting a signal from one of the engine's sensors that it likes, and thus can't control the transmission properly.

My manual (Chiltons) has a wiring diagram for a Calif 5.8/E40D/Mass-Air in 95, EEC-IV, not OBD-II. (The pin count on the PCM is different on the 96s). I also ran across an ECM on some parts site for the same set-up (5.8/E4,Mass) that listed it as Calif/PA. Some one here on FTE has mentioned that their 94/95 purchased "up'nawth" has OEM mass-air.

The AOD is not computer controled, so the FMS conversion kit won't work on the E40D.

The only way to use a mustang or lightning kit is to use a stand alone tranny controler such as the one from Bauman (expensive). This was one of the things I researched when I first got here.

However... What about beefing the E4s internals?

And can the later year production units (96 & up) be adapted to our model years?
