Gear Vendors and US Gear are the two I know of.

A complete install of a GV (do it yourself) is about $3000 when all said and done, maybe more. The US gear unit is a little cheaper. Not sure what your budget is, but to me it's a waste of money. If you have a stock to mild engine, you're much better off getting a 700R4.
