Saginaw 3 speed to Transfer Case Adapter

[mi396ss]

I have a 1972 K10 that has a Saginaw 3 speed in it. I pulled the transfer case and transmission and I am wondering how you get the adapter separated from the transmission? I took off the 5 bolts holding it to the transmission but it will only come back like an inch. Any help is appreciated.

Just guessing here but it my be like the 4 speeds and you will have to pull the tapered pin from the reverse lever. This will allow the slider to pull loose from the gear.

Having never seen a 4 wheel drive three speed this is just a guess and I could be full of it.
Most manuals I have worked on were 4 speeds.

I figured it out. It’s actually a Muncie HD 3 speed and not a Saginaw. I rotated the adapter and was able to see a circlip in there that needed to be squeezed. I’m all set. Thanks.

FYI. I’m guessing this was kind of rare but this K20 had this Muncie 3 speed backed by a NP205. There isn’t a whole lot of info out there on these.

Here is a picture of it with the adapter. I can’t get them back together now, not sure what I’m missing here.

That sure looks like a car style 3 speed. I bet you could pop a 4 speed in there. I've never seen one. That must be rare. COOL!

I knew the 3spd was standard but never saw a 3spd K/20. I had a 3spd '71 K/10 with NP205 but never had that apart. The 3spd K/5s coupled to a small transfer case, maybe a Dana 20?

That’s what this is, 1972 K10 with 3 speed backed by NP 205.

I remember having the same issues as you are.
The adapter is a tight fit and the bolts will draw it in if you tighten them evenly, a little antisieze helps too.
It's actually a very heavy duty transmission except I hate the non syncronous 1st gear.

That’s it. Ok, thanks. I’ll try using the bolts to get it back together. Any idea what it’s worth?

Parts for these aren't easy to find, it doesn't neccesarily mean its rare or valuable but you don't come across these trannys everyday either.
I do keep an eye out for them just to have as a spare. My guess or hope would be under a $100.

Ok thanks.

Thanks for posting pics up! My dad had a 71 K10 30+ years ago that had the same setup, before he swapped a 465 in it. You don’t see them very often in the K trucks.
