Hi,
I have this also posted in the trans. area and no one has answered. Asked this question before, but must have said it wrong, the response I got wasn't what I meant. So here it goes again- Have an 86 4x4 with 460, is the 1980 -86 the only C6 and transfer case that will bolt right in or will the middle to late 70s or newer 86 up fit. Someone told me once that the early 70s style had the transfer case not bolted directly to the back of the trans. and the newer trans. are a overdrive and won't fit, is this correct? Any help is greatly appreciated!! My tranny now is completely out and has been rebuilt before by the last owner and I think it got messed up inside pretty bad, so I am looking for a different one to put in it.

 

Yes and no.

Earlier combos are referred to as 'divorced' transfer cases and had connecting linkage (short driveshaft) between the transmission and the transfer case.

The one you have should be mated together.

No C6 is overdrive, but during the late 80's into the 90's Ford also used AOD's and E4OD transmissions.

For ease of application, you want to find a C6 that attaches directly to the transfer case. You can make most anything work, but might end up with some custom work.

Is this what you're looking for? Or did I misread your question? If all you need is the transmission rebuilt, it's probably cheaper to have your current one rebuilt by a reputable shop.

 

Thanks MTFLAT,
That's exactly what I was wondering. I know the C6 doesn't have overdrive but didn't know if one of the newer trans. with od would mate up to my transfer case. So, only the 80 to 86 with the 460 will bolt right in with no big problems and a lot of messing around?
Thanks in advance, Joe

 

You can also use C6's from 351M's and 400's. Like stated, be sure to get the ones that had the transfer case directly mounted, generally 1/2 ton (150) from the pre-77.5 trucks. 77.5-9 had the attached t-case, while 77 and older 250's used the mentioned divorced case, which mounted to the frame, not the transmission.

 

Thanks fellro,
So a 79 with a 400 will work, because I have seen a few of those around.

 

Same bell, should be the same depth, I think that is only an issue with manual trans bells, but the t-case will mount the same.

 

J The C6 transmission has a molded bell and has to be used with the correct engine family which there are three of. The 385 series (351M & 351/400M, and 460) are one, the FE (352, 360, 390) is another, and the Windsor (351C, 302, 351W, I-6) is the third. There are different tail shafts including one for the 4X4 that can be exchanged.

The transfer case used on the 86 was a Borg Warner 1345. The above mentioned divorced transfer case was only used on 250s & 350 and those trucks are known as hi-boys. The same year 150 didn't use the divorced t-case and is not a hi-boy.

There is some good an some not so good imformation floating around in this thread.

Here's the long of it:

Ford used mated transfercases in all models starting in 1976 except for the 1976-77 1/2 F-250 4x4's. These maintained the divorced t-case until 77 1/2 when the "hiboy" went away. But the hiboys also ALL had FE motors, so you wouldn't be able to use one of these transmissions anyway.

The Ford C6 started going away in the early 90's and was gone by 1996. It never went computer controlled, so you luck out there.

And as was said above, the 351M, 400, and 460 share bellhousing patterns so automatic transmissions interchange between them.

From 1976-1996/7 all fullsize Ford transfercases share the same face pattern and input shaft spline.

So here's the short of it:
You need a C6 from any 4x4 truck made between 1976 and 1996 that came with a 351M, 400, or 460.

Now if you want to get real fancy you can use an E4OD from a 1991-1997 truck that had a 460 and 4x4. It's more or less an overdrive C6, but they were ALL computer controlled. This means you'd either have to adapt the factory computer to your truck (alot of hassle) or buy a stand alone transmission controller (alot of money).

hey jnehring,
not sure where you are located but i have a c6 i'd be willing to let go for cheap. It's got a 351M bolted to it (in a 77' f-150). Got a np205 on the other end i believe. I bought the truck for parts... pm me if interested
