H2 (2004) Total Failure
Had the total joyeous failure of my H2 tonight.
Firstly all my gears stopped working. Was cruising at a steady 50mph then all of a sudden no power through transmission.
Managed to pull over much to the amusement to the rest of the rush hour traffic and stopped the car.
Then i switched the engine off.......
leading to problem number 2
It will not start...... The starter motor turns but refuses to engage.
Its got a new battery - no probs with power. In fact there was no voltage drop for the 2.5 hours with my hazards on it took for the recovery truck to turn up. 
Now for the fatal words..... any ideas...... |

Re: H2 (2004) Total Failure
Sounds like maybe the starter solenoid as far as the starter goes. Just go under the truck and give the starter a few light taps. Then try starting it again. As far as the no power through tranny. Check your fluid level. Try smelling the dip stick if it smells burnt probably a band.

Could be ignition switch. Believe it or not. Do a search.

Re: H2 (2004) Total Failure
As it continues...............
Mechanic came out to scan it today. No fault codes at all. Engine and all gearboxes are clear. The starter is appartently working and turning the flywheel but nothing after that. He reckons the flywheel has come off the engine somehow therefore leading to my loss of transmission and starter not working.........
Sound plausible???

Sounds possible, but unheard of! Did you hear anything before you lost power? Has the flywheel ever been removed for any reason?
Any easy check would be to remove the starter and have a look at the flywheel.

Heard nothing when I lost power - one moment it was there then it wasn't.
As far as I know it has never had any problems with the gearbox/fly wheel but I am going to check it out.
Think it WAS a UFO stun ray......... |

Re: H2 (2004) Total Failure
After further thought, it sounds like a torgue converter failure. Check your tranny fluid for signs of burning fluid. May not be a bad idea to drop the pan and look for metal.

Re: H2 (2004) Total Failure
Sounds possible but weird. Might be torque converter except for the whole deal with the starter and it not cranking the engine over. You can see the fly wheel clearly if you remove the shield from it. It is like a stamped steel piece that is held on by a few screws just remove it and take a peak. Good luck.

Re: H2 (2004) Total Failure
On the bright side Karma does strike.
I have a mate works on the radio - early evening show - who took the piss out of the fact i broke down live on air. - I did wonder about the number of drivers who flashed their headlights at me -
When he finished his show his motorbike failed to start and was promptly stranded.

The ring gear is attached to the torgue converter, hence if it fails, no spin on the engine!

Re: H2 (2004) Total Failure
well I have personally replaced flywheels on GM products that tore free of the crank bolts. had a couple that were broken but still functioning but with extreme weird noise. the older 2.8/3.1 were great for this. I'LL ask my buddy at the dealer if this has been an issue on more of the 6.0s.

Ok I thought the fly wheel was attached to the crank shaft and the torque converter was attached to the flywheel. So I thought the flywheel was a direct link between the starter and the crank and that the torque converter was the link between the tranny and the flywheel. My bad.

No you are correct. Only Chrysler used a ring gear on the torque converter with a flexplate to the crank. GM has never used a design that wasn't turning the crank first from the flexplate. |

Re: H2 (2004) Total Failure
Well its gone to get fixed. Asked them about it apparently they have had a load of escalades with this problem but no hummers. I am the first - typical - I was not even hammering it when it went, which is probably lucky. Find out tomorrow how much damage has been done.
