Ill be honest with you guys, I didn't do a search, usually because when I do the information is not tailored to my needs.

If this has been asked before though, feel free to scold me.

But, basically I am going to be starting a new job soon and its going to leave me with a lot more money than I have ever made before. Not that I'll have money to burn, but one of the things that I would like to do is restore my truck (or kind of restore it). I figure that I can have a brand-new '96 F350 for under $20K and it'll all be paid off.

But, I would like to know if anyone has heard of, or maybe even knows someone who has put a 6-speed Eaton Fuller transmission into a Powerstroke truck. I am really curious to know what it might take to make one fit. If it takes a huge body lift or a bunch of unattainable parts that will have to be made, then I'll drop the idea.

In the meantime, it kind of sounds like a fun thing to go about doing. Especially since I think that having a gear more for my selection would be a good idea.

Does anyone here know anything mechanically about the Eaton 6-speed as far as what it runs off of and if I'll have to run lines to it? Or is it more or less self-contained like my ZF-5? I am pretty sure that nothing is air-operated because there is no hi-low range selector or anything like that.

Can it even be done, or am I just spinning my wheels thinking about taking something pretty good to start with (ZF-5), and playing with it?

With the Eaton Fuller you'd run into an unobtainable transmission-transfer adapter; also, I don't believe the Powerstroke has an SAE #3 bellhousing at least in Ford applications (maybe in Int'l??).
You'd be better off looking at the ZF-6. Even then I know it is longer and the driveshafts would need alteration, also the rear support crossmember, but it has probably been done.

You're probably looking at a lift, since an Eaton-Fuller tranny is BIG (that is, physically large compared to the ZF-5). For what you said in your post, why not a ZF-6 swap from a Super Duty? Wouldn't be re-inventing the wheel as its been done before. Myself, I'd sure like a 2 spd. splitter, something I could do on the fly like in the old 2 ton trucks.

Ahh, I was just throwing out an idea.

I figured a couple of things: 1) that if they used the Eaton-Fuller in the F650, then why not be able to put it in the F350? and 2) transmissions seem to all cost about the same brand new, so why not take a heavy-duty truck name and put it into a light-duty (maybe high horsepower) frame?

I know that the F650 is a Medium-Duty truck, but they also used the transmission in International trucks with the same motor (I believe). They just called it by the "x444" model number instead of "7.3 Powerstroke," right?

I'll have to do some in-depth research to see if it can be done easily, but I'm pretty certain it can be done.

I guess the key word there is "easily." Meaning that I'll have to see if a bell housing has been made in the past to do this, and I would have to make sure that I wont have to body lift the truck. I personally don't like body lifts. Plus, if you have all of your controls like 4x4 and transmission shifters going through the floor, then you have to modify them. Then there's pedal concerns, electrical, other lines and hoses...

Given that the Eaton can be had in an IH with a TD-444E (Powerstroke), it should bolt up. Just need the proper bell housing. Now the rest (clutch and control to pedal, shifter) may get interesting. Post back when you figure things out, it may be a long winter and this will be something to ponder on!

There is a lot of info on trans swaps over on 4bt swaps .com Just about anything you can dream of has been proposed or completed over there. Be prepared to be lost for a while.

The bottom line is unless you are the fabricator type to the level of using or being familiar with a lathe, mill etc. the ZF6 has been done (member here I believe) Biggest issue is having to use the transfer case too. Remember the shift quality and speed of a 2 ton medium duty truck is not the same as a 3/4 ton......

Not trying to talk you out of it, just kicking the pros amd cons around. Nothing wrong with a virtually unbreakable trans.

Out of the diesel capible (remember ratios are important on a diesel) trans availble, the NV4500 has durability problems and ratio problems, the NV5600 is scarce and expensive, the G56 same and a lot of people end up back at the ZF6 again, the only one with a cooler and lube pump.

Check out 4bt.....
