I removed my 302 EFI and installed a BadA$$ 351W I built with carb. I have the AOD in it right now. However I am looking for a donor truck with a sloid front axle and a C-6. I could help ya up to the tranny swap. What engine do you have currently?

It's not difficult to do. There will be a share of people that tell you your crazy, gas milage, pull codes, fix the problem etc. etc. etc. The choice is yours. There are alotta aftermarket products for your truck, and the system is pretty reliable. However, I changed mine because it is a "TOY". Also take into consideration that if you do not have a donor truck, there is down time. Not to mention a, not a major cost but a wallet denting cost involved. There are some pretty sharp people on here who have probably have chewed on the same problem your having with your ECC. Give them a chance and you might be suprised.

Thanks ALSAIR. It's good to know that there are others who share the same thoughts. I want the change 'cause I'm from the old school and I don't believe in all the electronics. For the interior and accessories, that's fine. Under the hood is just wrong. I have a 1955 Crown Victoria and it has had less problems in the last 40 years then this Bronco that I've had since it was new. I love Bronco's but the electronics, now, have to go. I know that changing from EFI to Carb is not difficult and switching from E4OD transmission to a C6 four speed with OD is not rocket science. A lot of my concerns are with the Shift-on-the-fly 4X4. That is one aspect I don't want to lose. Plus the CRUISE control. Is it controled by the ECU? That is something I have no knowledge of. IF it is controlled by the ECU...is it something that will fail when I disconnect all the EFI components? I have many questions as you can tell. I went to a VoTec high school in the 60's. I've built engines and transmissions. I'm just lost with the electronics.
Thank you for your thoughts.

well i think your gonna be a little disapointed. ok...the c6 is a 3 speed, no overdrive, youll want a AOD (3 speed, with overdrive). the shift on the fly 4X4, well that is controlled by the ecu, because it needs to know when to shift so it wont grind the gears in the t-case. and the cruise control is also controled by the ecu.
the distributer and ignition system will need to be changed, the distributer has electronic advance, controled by the ecu.
also, when you take out all the computerized stuff, your gonna have a couple miles of wire, and many sensors all over the engine with nothing to plug into.
well good luck and have fun. keep us updated if you do this, and we're always here when you have a question

Just to let ya know, you will be busy tracing wires for days. Like JetBlackBronco said you are going to have miles of wire! You will lose Cruise control, Shift on the fly, you will probably lose you ABS as well. Your check engine light will constantly be on along with the ABS light and your battery light, the tach works off of the ECC. Unfortunatly you cannot get what you want which is the best of both worlds, It is alotta work. If you have the time and the know how, go for it! But you can only get an overdrive unit on a C-6 without a transfer case, then you lose 4-wheel drive. Locate a AOD if you want O.D. but you have to change the flywheel. There is a long list of changes that have to be made. I will help you, if you decide to do it, as best I can. My advice would be to find a donor truck with a C-6 (will not have O.D.) and a 351W and transfer case and do a swap. It will be quicker and probably cheaper in the long run my friend.

Thank you all for for your knowledgeable information.I will have to give this conversion a great deal of consideration. At present my ECU is in a California shop (ECUDirect) being refurbished due to the fact that Ford no longer carries the ECU as a new replacement. Even when it comes back and everything is OK I am still going to seriously investigate releaving the Bronc of its electronic shackels.
ALSAIR....you can increase your gas milage by counterboring a step on the bottom side of the secondaries and polishing the insides and sharping the top of the secondaries to reduce drag. This process will reduce drag and the counterbore step will atomize the fuel better. LOL

JetBlackBronco...I see,on your bio's, that you have duel exhaust. Is it true duel exhause? When I installed AEROTURBINE I could see no easy way to get around the transfer case. In Maryland the emission laws state that a duel exhause is only legal if it came from the factory that way. I investigated and Ford did not make a Bronco (1992) with duel exhaust.

O.k first the flywheel can stay. It is the same. Second yes a aod will give good gas mileage but the computer dont control it thats the E4 trans which will have to go.
Second wiring is simple. locate the red white wire that send s the oil pressure and the white red sends water temp. Then you need reb blue at the tfi and the red and green they hook up to your dura spark so you have spark. Leave the tfi coil in it works great. As for the altenator I'd have to read a manual over again but it hooks up just as easy or install a chevy one wire only have to drill it out a little and much cleaner.
Good luck and if you were closer I'd help but p.m me or email I can walk you thru the wiring.
I used a ford truck diagram to convert a 89 f.i vehicle into a v-8 carbed because they are easier to read.
Also as for a donor vehicle look into finding a 85 model they were still carbed. All the parts from it grill to *** will fit it as well.

[QUOTE=pacer88220]O.k first the flywheel can stay. It is the same.
A flywheel from a 351W attached to a E4OD is not the same as one from a 351W to an AOD. The mounting points are diffrent, as well as the balancing. My buddy who works at Ford and I have been through this as well as multiple people on this sight. As for the flywheel on a C-6, it CAN be used for an AOD. But he has an E4OD and wants to go to a C-6 or AOD. Flywheel has to be changed. As far as wiring a duraspark dizzy with a TFI coil, that is not aproblem. I think what he wants is to keep all the Shift on the fly and cruise intact and that will not be possible.

and e40d and c6 flexplate are the same. the AOD is the oddball and cant be used on any other auto tranny period.
Bronco Butch. dont let the efi scare ya. it is far better then any carb setup you can imagine and the fact mpg, and reliability are way better as well. you just need to understand how it all works. check out www.fordfuelinjection.com
you can buy ecu's from napa as well with a core charge for your old one. the thing is what was wrong with it to begin with. there are ways to find out real easy before you take it to some shop. also if you have any emissions in your area going back to a carb setup would be illegal and you wouldnt be able to drive it. if its really bad just get it running and sell it . then go out and find an 84-87 with a 351w they will all be carbed.
