SOURCE: 2004 Hummer H2 leaking water on passenger floor

never worked on a hummer but rule of the day is that there always is a drain on the firewall on the engine side. usually a small rubber hose about two inches long direced downward. Usually you can stick your finger in there and clear it out. Don't shove anything hard into it or you can punch a hole in the evaporator core.

SOURCE: 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.

SOURCE: key will not turn to off and battery dies after several minutes

chances are it is your tumbler or parking gear switch. you can replace the tumbler (ignition switch) or the parking gear switch is not recognizing that the vehicle is in park and preventing the key from being turned off

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

Loss of engine power/transmission 2001 chevy tahoe over 65 mph


Sound's as though a previous owner installed a speed governor so that the engine would not exceed the nationwide 55-65 mph speed limit average. This most likely was a company owned vehicle or owned by someone concerned about speeding ticket's or excessive speed by a teenage driver. It can be uninstalled by an experienced mechanic. Unless this poses a problem while driving on an interstate, you may wish to leave it as is.

Does the trany fluid smell burnt? Might want to have the trany flushed - torque converter too - and replace the filter in the trans. FYI you may know this but it is not recomended that overdrive be enabled when pulling a trailer - especially a heavily loaded one. Does your town have lots of hills - this is an added stain on the trany.

check to see if the serpantine belt is still there. It sounds like like it broke. this belt runs all of the accesories on the vehicle including the water pump. So if this happened it probably starting running hot too
