As far as what I have seen in magazines and so on , a gear vendors is almost like a second transmission , that goes behind the main trans, that add's extra gears.
I am sure the install couldn't be all that hard , but the driveshat will have to be shortened in order to clear the gearvendors unit.
Good Luck with your project if you deciede to tackle it !

Heat is a transmissions worst enemy. Change the oil regularly, install a heavy duty transmission cooler and a guage to keep an eye on the temps. Don't run it over 200 degrees for any long period of time. Cost of a cooler will run between $100 - 300 depending on which one you want. I have the BD double stacked 12volt fan cooled unit. Cost me just under $300. As soon as I see the temps approching 180-190 degrees I turn on the fan and it never gets over 200.

The Gear Vendors unit is good if you have a 2 wheel drive unit, as it fits last in the drive train, before the shaft. If however, like me, you have 4 wheel drive, you need the US Gear variety, that fits on the back of the main tranny, before the transfer case, so giving you overdriven, or underdriven ratios whilst in 4 wheel drive. The cost of the unit is $1600 for a Ford application and can be attached in 4 hours, Both drive shafts need altering, the rear shortened, and the front lengthened. The main benefit is the ability to happily tow a full load in a ratio higher than 1:1 - drive (over) is an overdrive, with overdrive (over) being a double overdrive.
Couple the benefit of the aux tranny with a larger cooler, and your towing experiences will be happy ones. Add a shift kit or shift enhancer to the mix, and you get a transmission system worth having.
