What tranny will work behind a 351 cleavland. I want an overdrive.

 

automatic? AOD/AOD-E

 

Sorry bout that. I'm looking for automatic with over drive. I've got a fmx in there now.

 

The AOD is an automatic with an overdrive. I't basically a C6 with an overdrive except it wasn't especially well planned out and they tend to burn up clutch packs.

 

Bill's right, the early AOD's were not the hot ticket but Ford re-invented them in the AOD-E. still not ALL that, they can still use some help. good news is that help is available. here is a good informative sight, i have no personal experience with them but feedback is good around some other forums. as with everything else, if you try to "save" a lot of money you may end up spending more in the long run. doing it right the first time is prolly the cheapest way to go.

AFAIK the AOD was a pumped up C4. There is a lot of info on this conversion in the engine swap and transmission forums. The AOD can be built very stout from a number of vendors.

 

The AOD can be upgraded with parts from the truck HD transmission. It's not as strong as a GM 4L60, but it can hold up to a street 351C if it has been built right.

 

I had heard that the aod was wimpy. I'm working out a deal with a freind who has a 351 cleavland with pantero heads thats close to 500 horse. If I get it I'm going to need something strong but with the e4od you need the computer. I'm not sure I want to mess a computer.

 

the AOD's need a controller too, it's not a big deal. the most important thing is that the throttle position sensor be adjusted right, AOD's don't use the old kickdown system.

 

i thought it was built after the c-4 not the c-6. the e40d was built after the c-6.

 

"I had heard that the aod was wimpy."

AODEs can be built to withstand up to 1200HP if money is not an issue. There's an article in the files of my forum about an FMX to AOD swap if you're interested.

"I'm not sure I want to mess a computer."

You can always build a C6 with an aftemarket OD.

The AOD actually shares much of its design with the FMX!

Out of the box, the AOD doesn't tend to withstand much abuse, but it can be built, as was mentioned, to hold a lot of power. One of the toughest AODs available is found behind the Supercharged V6 Thunderbirds ('89 - '93).

AODs do NOT require any computer input. The AOD-E DOES. The AOD uses a cable connected to the throttle and an internal centrifugal governor to determine shift points. It's pretty easy to set up if you use an aftermarket (Lokar, for example) cable designed for the application.

There are a number of AOD gearsets available on the aftermarket and a number of varying opinions on how to build one. As was said, search around for examples on the web and look at others' recipes for a good build.

I've had good luck with AODs, put 2 of them through quite a bit of abuse, and while they're not exactly as strong as a C6, they have potential.

 

Thanks for all the replies.
