just stick with the E4OD trans. Either rebuild your current one or buy a factory replacement. Also, STAY AWAY from shift kits. Aperently the kits are not compatible with the newer Ford trannies like those kits claim. Mine went out twice because of them, and partially from guy who rebuilt it the first time for me.
As far as going to an AOD or a C6, Why go backwards in technology? If your rig has the gas hog of a 5.8L like my '90 has, your going to need the extra over drive that the E4OD has. I had an '89 with the 5.0 and the AOD trannyand it was marginal as far as gas mileage was concerned.
Hope this helps

I'd stick with the E4OD as well, and I wouldn't write it off 'cuz of a rough reverse engagement. The AOD is a piece of crap unless heavily (and$$) modified and the C6, while a good trans, is technologically backwards.
Ford has a ton of TSB's out there in regard to the E4OD and you might have a problem that is easily fixed without a rebuild. And if you go to a tranny shop, get a 2nd opinion from another one as well. Most of them would be happy to do a rebuild, even if it doesn't need it.

Stick with the E4OD. I have 150k on mine, and it's never been rebuilt. I do have a shift kit installed, and it is a great improvement. Check your motor and tranny mounts. I am guessing you mean that there is a clunk when putting it into reverse? My motor mounts went bad and fixed a lot of problems.

yes id say keep the e40d, if youre concerned with strength, there are some nice buildups, jet, art carr, and so forth...note these are $$. The c6 is a beefy trans without overdrive, unless of course you add it on, again $$$ and alot of weight and modifying. If you wanted to go manual, this is a bit of work but i would reccomend it over switching to any other auto beside the e40d

I dont understand why everyone thinks the e4od is such a great tranny. it costs so much to have one rebuilt, double the cost of a c6, and still more then a beefed up aod. Also its electronicly controlled, which to me sounds like one more thing to leave you on the trail needing a tow from your buddies if something goes wrong. Also stock for stock the aod is more proven then the early e4od's. now if im not mistaken they made some improvments to the e4od but not till 94 or 95. This is similar to all the guys running the electronic 4x4 and wanting to go back to the manuel shift t-case. its one less thing to go wrong , and linkage issues can be fixed on the trail. Now im not trying to start anything here just wanting to learn as much about these rigs as possible and hear what everyone has to say about this. Thats why we are all here right!
Thanks

Well, I'm not a trail runner, but if I was, I wouldn't be using an AOD or a E4OD. My Bronco sees duty pulling a small boat and as a skiing rig. Personally, I'd rather have a 5 speed. But I bought this rig when I was still married and the ex wanted the AT, even though she can drive a stick. (we had small kids at the time and she thought it would be easier) And I do hate the electronic transfer case and the auto hubs.

A 5 speed man would be a great tranny , only problem is finding one that will handle alot of abuse. I dont think the mazda tranny would be very good. if it was for trail use id go with np435 tranny. its got low gears and is damn near bullet proof.

Keep your E4OD, it's basically a C6 with overdrive, while the AOD was just a hopped up C4.
I've got a C6 in my '78 with E4OD gearset(lower gear ratio, better strength). As to the electronics failing, you'll experience mechanical failure that will leave you stranded before you suffer an incapacitating electronic failure.
Just my .02

maybe for you who is driving a 78 that has none. The e4od is in the newer fuel injected broncos were electrical issues are more common than mechanical failure.
ive never heard of e4od gears being put into a C6, that tranny is already geared low and being a 3 speed why would you want to be geared in the tranny lower. fill out your signature with some information on your rig . Like tire size, gears and so on.

Ive also had no probs with the e4od in my 96'. But the aod in my 90' was garbage so I installed a c6 which was no kidding a direct bolt in only the tranny cooler line locations are difrent. It runs great but OH MY GOD did it kill the gas milage. But no prob for me I have the other truck for road trips.

ONE more on this,
I have a 302 EFI with the E4OD, but the 302 is shot. I was considering transplanting a 351W from an earlier truck, to get away from the non-controllable computer. I know there are aftermarket adapters to run the E4OD (sans no computer)
will the E4OD mate to the 351W???
alternatively, I could use the 351W and AOD will the AOD mate to the xfer case (non-electric floor shift) ?????

Where can you find these TSB's I am having a problem with mine I think it could be an engine problem i have yet had to time to check it out or have it checked out but i would like to see of there are any posted TSB's about my problem.
The Problem: my truck seems to "slip" while driving creating a shuddering...I am also noticing an odd idle while I am stoped at a light.
thanks for your help.
