Ok, I know this thread is OLD, but, I didn't want to start a new thread for a related question. My truck has a C-6 tranny which probably needs to be rebuilt. Would the fuel mileage savings from swapping in an AOD be worth the trouble of doing so? Also, just how much of a durability hit would I take from doing that.

This for your '77 400?

If so, the AOD will not bolt up. It is produced in SBF pattern only, and maybe some smaller engines, but not 335/385 pattern.

Adapters are over $700, and you'd have some fiddling to do.

Plus, a beefed AOD is $1000-2000+, depending on who you buy from.

Figure your current mpg and and then figure a 20% increase. My guess, you are going to be figuring on 10 mpg to 12 mpg. Do you drive enough miles to pay this back in any decent length of time?

E4ODs will bolt up, again with some fiddling regarding flex plate probably. Contrary to a prior post here, the E4OD is completly different than the AOD. It requires a $500+ controller to run.

Tough sledding when it comes to an OD conversion I'm afraid.

Yep. I was thinking of puttin it behind that old 400. Thanks for the info. Even if it wasn't quite what I had hoped. Looks like I'll be sticking with the c6 and just being easy on the gas......who am I kidding, I got a lead foot....

I know this thread is super old, but I'm trying to figure out some of the differences between the c-6 and the e40d. According to my VIN, I have the e40d, and it feels like it is on the way out. Since the e40d is pretty spendy to rebuild/replace, I wondered what the options were for swapping to the c-6. Seeing that I just bought the truck for $600, I'm obviously not looking to spend much more than that to fix it. I'll deal with it when it comes, but I want to do my homework now so that when it comes I can have something lined up. So, in short: Are the c-6 and e40d interchangeable? If so, what parts? The whole thing?

To install a C6 where an E4OD used to be can be done. It is not a direct bolt in.

The C6 is shorter to you will need to change driveshaft length (2 if a 4x4.) The trans crossmember needs to move, too.

You will need to install a vacuum line to the vacuum modulator on the trans. On a gas engine this is a 2 minute job. You attach one end of the line to the intake manifold and the other to the modulator. A diesel is MUCH more involved. You need to install a VRV assembly on the injection pump. It's even harder if this is a Powerstroke. I don't even know what that looks like.

You'll need to wire the neutral safety switch since it is different than the E4OD switch. Same for the backup lights.

The PCM (assuming you have one for the engine) is going to throw A LOT of codes. You may be able to change the PCM to a manual trans. Of course ignore this paragraph if you have an IDI diesel.

It's also interesting that you found this out from the VIN. There is no information about the transmission in the VIN.

Thanks for the quick reply! I got the info from my VIN explained on this website: 1983 Ford Bronco Diagrams picture | SuperMotors.net

knowing that it is a lot more involved that I originally thought, I'll have to keep a lookout for all of those extra pieces....
