From what I have read in other posts here, you would be better off trying to mate an AOD to the truck. The E4OD is an electronically controlled transmission. Not that it couldn't be done, but it could be time consuming and expensive.
an E4OD is a beefy tranny, just fussy and computer controlled. So the best thing to do is put a filter and bigger oil cooler on it. Second best thing you is find a computer out of an IDI diesel that had an E4OD because it will be a stand alone unit only for the tranny...hence less wiring and headache.
Im sure an AOD never came behind a 460, they are only light duty trannies like the M5OD 5 speed in F150s.
Anticipate spending lots of money doing a swap like this, unless everything is laying around nearby. I for one, would like a built AOD behind my 400, and so far this is what I have considered: http://www.transmissionadapters.com/Ford%20429-460.htm
Pud,
I have an E4OD in my back yard, and have thought about the using the IDI computer on my 400. Do you know someone or have you found a site that shows a successful IDI computer swap?
wouldn't it be more cost effective to spend $400 on the Bauman Engineering E4OD stand alone controller than spend 7 bills on the AOD conversion kit and then still have to beef up a tranny?
Well, in my case, and my case only, it's for an 88 Tbird, and an E4OD won't fit. In a 4wd truck the E4OD makes better sense, and personally a ZF5 speed makes even more sense, IMO.
For $2500-3200 you can get into a gearvendors over/under drive. That will give you 6 gears and a far better range than a 4sp tranny. It is tougher than any of the above trannies and, when matched to a c-6 it will be a bulletproof system. The final drive will be about .8 lower than your gear ratio ie a 3.50 will be about 2.7:, 4:11..3.30 ETC. The average fuel savings is over %20. They can be set up to go through all 6 auto which keeps you in the best rpm range of your engine or you can click it in as a 4th overdrive and/or control it as a manual setup. I'll likely put in a B&M ratchet and a shift kit in the c6 to match it. It will automatically disengage when you go into 4wd as few if any need overdive in 4wd. This system has the best rep of any on the market and the basic unit will handle over 900hp and tow 25K. You can put them on nearly any rig.
The final drive is about the same ratio as the ford overdrives but you get a lot of meat in between for what is proabably a lot less $$.
I'm surprised more folks aren't using this system.
I am interested in the GV overdrive. I couldnt find on the website how the compatibility is between a vacuum controled C6 and an electronic controled OD unit performs. I think it seems like a neat idea, but it have doubts that it would be seamless trying to shift 1-1OD-2-2OD-3-3OD, not to mention what happens when you hammer the throttle at around 55mph, what gear will it find, and will the C6 and overdrive "agree" with each other. It seems like it might perform more smoothly shifting 1-2-3-3OD. Has anyone installed one of these that can fill us in on the details?
Roger, I've always suspected their durability and strength by way of unknowing ignorance. Thanks for the info. Of course the price is still tough to chew, lol.
all that i've heared...not experienced...is that operation any way you choose is seamless to include vacuum and mechanical downshifting but those are technical questions I now want answers to as well...will check it out.
