Saginaw 3-speed Transmission Capacity
Title kinda says it all. I repaired the rear oil seal in my 1969 GMC half-ton, and now I need to know how much to buy to fill it back up.
I imagine that I fill it up to the bottom of the fill hole, but how much is that? I can't find it in any of my books, and I'd rather not have a(nother) bottle of stuff sitting around collecting dust, nor do I want to make two or three trips because I didn't get enough. Any help out there?

Re: Saginaw 3-speed Transmission Capacity
It will hold 3 pints when empty. Now would be a good time to pull the bottom plug & change it all. Yes you fill it to the level of the plug on the side.

Re: Saginaw 3-speed Transmission Capacity
Most (all ?) do not have a drain plug, remove the bottom tailshaft bolt, that will drain most of it out. Put some sealer on the bolt before you re-install it.

Re: Saginaw 3-speed Transmission Capacity
Mine had a drain plug, so it was already drained. I got my three pints in, and only one half-full quart bottle left over. Man, that fill hole isn't easy to use. But, the way I figure it, I've now got another 150,000 miles before I worry about it again.
