So I really dig this kind of a setup. Dual Range Auxiliary Transmissions, Overdrive and Underdrive
But I am not a big fan of changing the oil in the overdrive three times as often as I change the oil in the engine. Any one know of some other units like this?

No one has one or knows of any one using something like this?

I have talked to a few guys online that have used these with good results
Gear Vendors under/overdrive transmissions the most awarded auxiliary transmissions.
I was going to put them on my previous truck, but it got stolen before I had a chance.

Not that one.. I know quite a few people who are using the GearVendor setup (Gear Vendors under/overdrive transmissions the most awarded auxiliary transmissions.) and a good friend of mine is a dealer/installer.. They're awesome..

I used the gear vendors on a drag car for years with no problems what so ever. I wish i had it now for my truck.lol

I was going to get a Gear Vendors for my 5 speed because there was too much lugging during shifts with a heavy load.
Installed a 3k GSK, cured the problem, no more need for an expensive gearbox.

Wanted it mainly for towing and fuel economy. Thanks for the replys
