I was wondering if the tailshaft of a fixed yoke 2WD C6 transmission is the same a (Highboy)F250 4x4 C6 transmission?

 

This is weird, because I too have the same problem. I just busted the tranny case in my 75 F250 4x (the one in my sig), today and was fixing to research it.
So can anybody clarify what I might be able to use for a tranny? Do I need to look for a 2wd tranny and swap tailshaft assemblies or get a 4wd tranny and add my tailshaft assembly?
PS, Thanks Tex for bringing it up!

 

You can use a 2wd tranny, but the tailshaft won't have the mounting hole setup for the 4x4 shifter. I've seen where guys have just used the 2wd tranny along with it's 2wd tailshaft and just make a bracket for the shifter. You'd have to get a short driveshaft with a slipyoke made. If you can find a 4x4 tailshaft, you should be able to swap them out and go from there.

 

Yeah, I know about the differences according to which motor you have, (351m/400,460, or 302,300, or FE, but since my high boy tranny is similiar to a 2wd tranny, except for the shifter on the side, I thought that it might just be a tailshaft swap thing if I find one. Or, do I look for a 4wd tranny like the married 4wd trucks use, and put my tailshaft on?

 

Sorry Buck, I guess I was typing. I'm wondering what the overall length difference is between the 2wd and the high boy tranny.

 

This sounds like a job for NumberDummy!

 

I believe the 2wd tailshafts are longer, but the exact length I'm not sure.

 

So I was out working on the truck this morning and took a pic of my tailshaft.

 

Thanks for the pic. I pm'd NumberDummy with the question and he was saying that a C6 housing is a .... so I guess I'll look for another housing and put my tail cone and shift linkage on it with or without having to change out output shafts. Looks like rebuild time!
