I was driving and my 2006 hummer and it cut off on me. I pulled over to the side of the road and waited. It started back up, but as I drove off it stopped again. I just changed the battery a day ago.

At what RPM 1st gear should shift on a H2 Hummer 2003

well is that hummer that a 2 ton or 4 ton vehicle ?

would take a lot of revs for first gear to make it roll from a standing start
think it will be fitted with an 6 speed automatic transmission

guessing only from my heavy vehicle driving experiences
first should change below 3000 rpm

if transmission was slipping in first gear you would know

ring up the local hummer service division for the correct answer

This sounds more like the pump having failed. Raise the hood and check the power steering resevoir for fluid. While it's running look inside and see if there are a ton of air bubbles. That would tell me that the pump may not be pumping the proper pressure. This is not a part required by HUMMER. Your local auto parts store should carry it as it is widely used by Chevy and GMC. There are a lot of substitute parts that will save you money. I have a factory manual and parts manual if you would like them. I can be reached at so feel free to ask me any questions as I am pretty familiar with these vehicles.
