Hey folks my name is Rob, I’m getting a 62 gmc and can’t wait to bring it home to Texas. Any how the truck is a long bed small window thru the vin it’s A two wheel drive but it has a hi low gear shifter. I didn’t climb under the truck to find out . It was a gift from the father in law.

That Hi/lo gear shifter isn't 4wd unless it was added aftermarket. It might be a second gearing for highway speeds. You're one lucky son of a gun to get that. I think it's called a browning gearbox or something. It gives our low RPM engines the gearing needed to hit highway speeds, though steering and stopping at those speeds isn't easy in a boat like these haha.

Welcome to the club. Can't wait to see more pictures!

Thanks I’ll have to look up that browning gear box. Appreciate your time

Welcome to the forum, Rob! My one ton Suburban has a Watson "Brownie" overdrive box installed behind the SM420 four speed transmission. It's possible you have the same, or at least similar, setup. Mine is shifted by pulling out a big knob mounted in the dash though.

A quick internet search came up with this -- https://talk.classicparts.com/threads/watson-auxiliary-transmissions.21364/. I'm sure there's a lot more info out there if you want to dig further.

I'd be interested to see how the brownie box is installed. If you can take a picture of the driveline when you climb under the truck, that'd be appreciated!

I would I still need to get it shipped to Texas . The pics I have I took when I was there early this month
