So i was thinking about a swap, and the car junkyard, transmissions are only $99.99 for a 4x4 with a 45 day replacement, so I was thinking of swapping my 3 speed C6 bronco with a newer E4OD or AOD.(not sure which would be better/easier) It took $80 to fill 3/4 of the tank, so $10 more and I can have a different tranny lol. My 1990 f150 has an 302 E4OD, but its 2wd and I'm happier with its mileage than the Bronco. I understand the bronco has a bigger and a carbed engine, but I'm sure the transmission will help too. The Bronco is an 87 with a 351w carbed, and obviously a C6 auto. I want the 4th gear because I drive this to school everyday and the lower RPMs will be nicer, rather than running at 2300 constantly with the C6. What all will I need to make this work? I know the front and rear drive shafts because the C6 is shorter than the others, but what else? The computer? Also what year of truck/bronco should I be looking for? What would be the best swap for me, an AOD or E4OD?
Thanks

 

AOD, non electronic overdrive, just need the shift cable and throttle bracket, I think Lokar parts for hot rods has the stuff.

 

Sweet thanks, and your saying the AOD should bolt right up, to the 351? Might be a dumb question, but at the junkyard how will I tell which tranny is which? in other words where are the badges on them?

 

this will show you the different pan shapes and bolt counts to determine the trans. i would definitely go for AOD, i have the E4OD and i hate it because of all the sensors and crap. plus for the cost of getting a remanned E4OD you can get an AOD from TCi that can handle up to 450 hp. http://www.transmissioncenter.net/PanShapes.htm

 

Awesome page, bookmarked it lol

 

glad it helped you

 

Yes will bolt right up you will need the 351 flexplate.

 

Well i'm back again on summer break, and I'm doing an EFI conversion now and again thought about the E4OD tranny, I would have a computer for the EFI anyways, so does an E4OD sound like a good choice? Wiring for EFI will be a PITA but might as well do the transmission while i'm at it. It will also keep me from taking a crown vic apart just for the 351 flexplate lol
