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

suggestion
ring up the local hummer service division for the correct answer

Hummer H2 2003, shifting problem


Yea, hummers are notoriously unreliable. They are gas gusslers too.
I'm assuming this is an automatic?
When the transmissions computer detects any malfunctions, it will give you a check engine light, or something along those lines.
Do the normal checks such as checking the transmission fluid level as per the user manual.

For further diagnostics you'll need to take it to a mechanic. It's impossible to diagnose a problem like this without driving the car and being able to reproduce the problem.
