That is because................ Hummers are no longer made: What I have and anybody can but on Ebay and where available on line is a Banks Power AutoMind Programmer 66112.

Per Summit Racing:
Not Available, No Worries, We Suggest...

This Substitute Part is similar to the item you requested.

Banks Power 66411 - Banks Power AutoMind 2 Programmers

Just to finally give a update. Since i wanted to really drive on the highway before giving a update. I The hummer gets up and goes in the first gear now. You can honestly tell a difference. I don’t think it’s making a difference on the mpg. I drove on the highway and had about 1/4 of a tank left for 200miles going 70 - 75 all I can say it is a definite improvement with response for city driving.
