4sd to auto
I'm switching my 72 k5 from a 4spd to an automatic. Is the transfer case the same or do I need to find another tansfer case? I'm also installing a 4" lift springs and blocks on it, what do I need to change on the front end?

First thing you need to do is wrap that 4 spd up and send it my way Bernie.

I "think" that a 4X4 turbo 350 auto will fit into that transfer case. Can't be a non-four wheel drive tranny. You'll need to install a radiator with the auto tranny cooling lines that go into it. You'll need to remove the flywheel and get a flex plate. What about linkage? Do you have an auto steering column?
If you're putting a 4" lift kit in it, then you'll need longer shocks and maybe a dropped pitman arm. There seems like a couple other things I'm forgetting too. Might need longer brake lines.

dubie.
"First thing you need to do is wrap that 4 spd up and send it my way" If you want the 4 spd set up it s yours, Although its for a 4x4 setup and I'm not sure if it will work for your application. batboy, thanks for the info, most of the parts I need to do a swap I have. I will be looking for a dropped pitman arm, so if you run across a used one or know where to find a new one let me know, thanks Fast68Chevy, I counted the splines and it turns out to be a 10 spline output shaft. The sites you posted gave me a lot of info and I think I'm probally better off finding a used 350/np205 to rebuild. Thanks for taking the time to research this for me. cheers ![]()

It's too bad you aren't closer.......I'd trade you all of your manual parts for all of my automatic parts. I would love to have a 4spd in my Suburban.
