transmission replacement

It has been many years since I had my Ford training but the way I remember the difference was the E was for vehicles with electronic controlled throttle.

I will try to locate this training material because I am seeing the same thing you are online. It looks like different websites are confusing these labels and actually interchanging them on different vehicles.

Good old Wikipedia doesn't seem to help either as some of these vehicles don't look right.

I will find the training document and get back with you.

I could not find the training book that I was thinking of but I reached out to one of my Ford dealers and they agreed that the E is for electronically controlled transmissions and the other are mechanical.

So all the drivetrain components inside them are transferable between the units but the electronics are not.

Hope that helps a little more.

Thanks... I understand that the guts are all interchangeable... but does that make the 04-08 W's or E's in the E150/E250/F150 4.6/5.4?

I am showing that it depends on years. The E didn't come in until 2004 but wasn't used on all vehicles. So I attached some pretty good detail that I just found on this but it appears Ford was phasing them all over to the E over a few years.

Make sure you see the 70 or 75 as that will matter for sensor location. Again the internal parts are the same but the 75 is stronger and I think has a second speed sensor.

Hopefully this sheds the light needed.

Thanks.
