Gear Vendors Overdrive from Motorhome

franks77 · Sep 26, 2017

Hope I’m posting in the correct forum—first time poster.

Just a quick question, anybody ever use an Gear Vendors overdrive unit from an old motorhome, and put it in a truck? I have a chance to get a Th400 with the GV unit installed pulled directly from a 1978 motor home. I’m guessing the motorhome might’ve have something like 4.XX rear gears where my 77 c10 has 3.42s—I doubt the motorhome broke 100,000 miles as the trans looks ok.

How feasible would this be?

Thanks for the replies.

Is the GearVendor original to 78???, if it is it may be the old small one, check to see if it has a TH350 yoke or the TH400 yoke, even if it's the small one grab it if the price is right, it's worth quite a bit on a upgrade to the new one, you'll love the GearVendor wish I'd a kept mine.. BTW, welcome to the site..

The gear vendor is original to the 78.

It doesn’t have a yolk. He says I would have to remove the drive line brake from the motorhome—which is still installed on the th400–and then add a coupler sleeve from GV. This is a picture of it

I'm confused. In post #3 I see a trans with what looks like and adapter with and emergency brake. In post #5 I see what I expect to see in a GV. If it's correct, how am I confused? I would expect #5 to be at the end of the trans in #3. The reason I ask is because the one I'm looking at locally looks like the pic in #3.....it's not long.

The first pic shows the tranny with the brake, you remove the tail housing on the tranny, the adapter on the GV replaces the tail housing, the brake then goes on the GV.

I'd be all over that set up if it's priced reasonably. Not sure you'd have enough room for the park brake set up so you might have to delete that, but if you could keep it, then it sure makes a rear disk brake conversion very simple.
