E4OD - How does it work?

[O'Rattlecan]

Does anyone here have any kind of comprehensive resource on how the E4OD works? I just want to know more about the transmission when it decides to hit the.... craps. I have an intermittant problem with mine but I just wanted to read a little about it. I know nothing of transmissions.

Dear R......the stories I could tell about mine. Electronic shifts with the OD............Einstein couldn't explain it.

Call me.....I have a thing concerning this you might consider.

10-4 my friend. I found a website that shows the tear-down to the solenoid pack. That's my first idea of what's broken.

When you get these manuals you better explain it to us.

Is that the trans chris has? He has been in his a time or two

 

[O'Rattlecan]

here's a summary.

It takes power from the engine, changes the gear ratio to maximize performance, and then moves that power to the driveshaft.

Ryan- the answer is magic.

Ford puts magic into the box when they bolt it into the truck, but after a while the magic gets tired and doesn't work so well anymore. Then you have to take it to the wizard who can put some more magic in it.

Ryan,

These links may help you get some more information on automatic transmissions. A E4OD is basically a C6 with OD added to the front of the transmission and a computer controlled valve body.

Ian, that was so funny it should be a sin.

Greg, thanks for the resources. I'm going to read those so I might know a *little* something before the manuals carl is sending show up.

If he rides his lawnmower up to your house I want a new video...

Ryan the solenoid pack is extremely easy to get to and remove. Pull your pan (careful, its full of fluid). The best way to pull down the pan is to loosen one corner more than the others and poor out as much fluid from that corner as possible; then unbolt the whole thing and bring it down very level and steady (trust me, there's not way NOT to make a mess without a drain plug).

Once that's down, you're looking at the valve bodies as well as the solenoid pack. The solenoid pack will be the big black box.

Unclip the wiring harness on the top-passenger-rear of the trans (this goes to the solenoid pack). There are a bunch of bolts/nuts that have to be undone (I wanna say there's 8 or 9), and then you can pull it out (easier said than done). The neck of the pack is pushed up into the valve body and, at least in my case, the rubber right was pretty well fused to the valve body. I yanked and yanked on that thing and FINALLY it gave way and pulled out. No damage done but by god my back hurt.

Awesome, I never knew much about automatics before this thread, but the links and the teardown pics help.

WHAAAAA...... THEY MAKE AUTOMATICS?

Okay, so it's the black portion... I've had the pan off before but beyond the filter/gasket/oil replacement, I've never torn it down any further. I know my problem is electrical. I was just out in the parking lot and was cleaning up the wire harnesses on the TPS and the Speed sensor on the rear diff. The rear diff harness was clean, but my TPS wire harness had a ton of corrosion on it. When I get home I'm going to clean it up even better and get some silicon to seal off that sob from the elements. If this doesn't work, I'll keep hunting. I'm not sure what a solenoid pack costs.

Whats the issue with your tranny? Im good friends with the tranny tech at our shop.. i can show him thr problem and he may be able to help you.

 

[O'Rattlecan]

Intermittent hard shifts. No rhyme or reason. It's got to be electrical.

Like I said, I cleaned up the wire harnesses (especially the TPS one) and it drove to work today smooth as butter. The only way to find out if it's fixed is to wait and see. I've been chasing this problem for the better part of 2 years with no solid answers.
