Tranny Swap

[3youngns]

Besides not having a OD indicator on the gear selector, is this a direct swap? I need to make my Bronco a little more highway friendly.

Why? C-6 is waaaaayyy better! BUT if you still want to do it, try advanced adapters.com, they may have more info for you.

Wouldn't I get better gas mileage with OD? Or will it not make that big of a difference? I dont want to change if there is no advantage.

I was going to swap my C6 for an E4OD, until I got all the cost together. Between the tranny and computer it was a small fortune. I am thinking about getting a gear vendor. It is less than half the cost of the overdrive. With the vendor your C-6 turns into a six speed with overdrive. In additon you keep the strength of the C6 and have a mechanical system vs a computer controlled. I have a link to them if interested.

We were going to swap my friend's E4OD out of his truck and put in a C6 but it couldn't be done.We talked do a few people and they said the electronic's between the motor any tranny have something to do with why it couldn't be done.They said if it was an A4od it would work.

What year truck was your friends ? I see no reason why you couldnt take the E4OD out and put a C6 in its place . The engine management system is seperate from the transmission controls and if its 95 or newer I know for sure that it gets its speed reading from sensor on rear end which feeds speedometer and engine management . The C6 doesnt care what its in just needs a vacuum line and its good to go . The computer in the truck for the E4OD controls shift points and line pressure nothing ties into the engine manegment system . I kept the E4OD in my bronco when I put a carbed motor in it . I did it using a stand alone computer from baumann engineering . I have all wiring diagrams for tying it in and have all ford service manuals from 88 to 91 for electrical diagrams . The only thing the transmission and the engine controls share is the throttle position sensor . That swap should be fine . Anyone else tried this ?

I agree, the C-6 can be swapped in place of the E4OD, and there is info on swapping the wiring to make it work. As for getting better mileage, The overdrive may give you 1-3 mpg more, but the C-6 is a more durable tranny. The E4OD is basically the same thing with overdrive and the electronics.
