OK, so I found out that the Lightning engine that I am putting into my 68 coupe was mated up to an E4OD transmission, not an AOD. So I am wondering
- since it seems like it is going to be a nightmare to get the Lightning's computer to work correctly without the tranny it is expecting to talk to, I have two questions:
1) Is the E4OD tranny a good one for a street car (i.e. should I consider getting it from the same wreck I got the engine from)?
2) Will the E4OD fit in my transmission tunnel?
Thanks! Thomas

"Full-size trucks first received the huge E4OD (Electronic 4 speed OverDrive) transmission in 1989. Internally, it is essentially a C-6 with overdrive added to the front (such as the A4LD is to the C-3) and an EEC controlled valve body. The E4OD is a very large transmission, and would require extensive modifications to the floorpans to fit in most cars. It would also hang very low once installed unless you were willing to increase the height of the engine and the transmission by approximately 3 inches."-

Just in case an AOD-E is in your future, here is a good site on the install:

I read that the AOD-E would not handle the torque from the Lightning's
351W. So I am still leaning towards just using the C4 until it breaks. I'm really getting a lot of different points of view on this.
Windsor-Fox has been helpful, but it looks like it might wind up being cheaper to just rip the EFI stuff off and go normally aspirated, which would be a real bummer. I want the EFI bits to work, but I am not sure it is feasible.

Should be some way it will work, and someone who has done it. As far as the EFI stuff goes, with today's fuel prices, I'm beginning to regret that I went to a carb.... as well as the responsiveness of an EFI is a bit better than the carb.
Did you contact Windsor-Fox, or just review the information on the site? If just a review, I would suggest you email them your questions.
There's more than one version of AODE. There's also the straight AOD. Since I'm sticking with the carb (for now) I have not researched all the ins and outs. I'm just looking at a straight AOD.

they have a 10 chapter guide which I would suggest you copy and read (or I could just send it to you from where I copied it). It's pretty detailed about the different transmissions, torque converters, valve bodies, etc. A very good read for me a tranny novice.

tech section, and if nothing is there, send them an email query. They built a 66 coupe which I think has a 351 and which they converted to EFI.
The Truth is Out There : ) Sometimes you just have to dig a little harder...

I have been trading e-mails with Windsor-Fox. He is probably sick to death of me by now. :-(
I'm seriously leaning towards just yanking the EFI stuff off and going with a normally aspirated motor for now. Looks like I will need a new Mustang computer and a wiring harness mod, to the tune of several hundred bucks, to make it work. And then there are no guarantees.

If you are going to be looking at a major output of $$$$... I think I would seriously consider going air breather now, if you can't find a solution, and later converting to one of the aftermarkets (Edelbrock had a tunable one with it's own "brain box"). You'd have to check what applications they cover.
Meanwhile, I'd go ahead and contact the others on the list. Maybe, if they don't know, they can give you a lead on someone who might. I've done a lot of research which ended up a case of following leads like that. Sometimes the led to good stuff, and sometimes they didn't. You never know until you try.

The best/easy OD AT for what you're doing is the AOD with the 2" OD band from the AODE and the hardened gearset from the 4R70W; the gearset put behind the 5.4L trucks (Lightnings).
For the best/strength OD AT setup, I'd go with an AODE with the 2" OD band and the hardened gearset from the 4R70W; giving a lower first and second gear ratio to help initial acceleration. You'd need a transmission control system such as the Baumannator TCS, to control the tranny though. You can get one here.

Thanks, for the input. From the start, i have been trying to stay mechanical vs electronic (as with efi type control system).
I haven't settled on any one unit yet. There are some other pressing issues to take care of first... like get the audio-video system installed the way I want it. (it all works, it's just the running the wiring etc.)
