Question about 2006 Hummer H3

1 Answer

Hummer H3 Losing power when shifting from 1st to 2nd gear.

I have had my H3 for about 2 1/2 years and now it is making a rather loud noise and losing power for a brief second when the car is shifting from 1st to 2nd gear. It is an automatic so I am only guessing that it is the shift between 1st and 2nd. When I shift the car manually it does not have a problem at all. Is this a transmission problem?

As odd as this may sound, try replacing the fuel filter.

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

Transmission making loud grinding/sucking sound, doesn't go when in drive or reverse


Is it an automatic John? When was the last time you checked the level of your ATF (automatic transmission fluid)?

There are many different types, so make sure you get the right one.

If it is a manual shift, check the gearbox oil level. If that is OK, you need a transmission specialist. Look in Yellow Pages.

04 focus gear stick wedges fron 1st to 2nd gear


Sounds like you have a bad shifter or a bad slave cylinder. Check the fluid in the reservoir and if you're losing some, then you need to see where the leak is coming from. If it's at the slave cylinder, you're in for an expensive repiar.

2000 Saturn Vue, manual transmission 5 spd, trouble shifting, loud knock (more like a BANG), when shifting into 1st gear... ..constant rattle while driving.....????


Try shifting into first without pressing the gas. If it is a slow decline before engine dies this is normal. If its a dramatic engine death, your clutch is to blame, if it still makes noise then its the gearbox. If you have a Mr. Clutch Autocentre near you they will test your gearbox for free as will many reputable transmission shops.

2005 impala LS with 3.8 eng. & 61290 miles. Transmission started shifting hard on 1st & 2nd gears, just out of nowhere. Is this a common problem on Chevys? Once on open high way vehicle runs...


two things: Pressure control solenoid first. Second issue is the valve body. These are common issues, but 9 times out of 10 its just the pressure control solenoid. Power steering, could have a leak, that causes air,which in turn causes noise or yes, a noisy pump.
