The aging H2

1. Radiator: The transmission cooler is connected to the radiator. The connections will fail after .... 30, 40, 50K+ miles. Upgrade your tranny cooler to an aftermarket unit.

2. Transmission: If these connections fail (from #1), they will allow radiator fluid leak into the transmission and vice-versa and will cause the radiator and transmission fluids to mix. You will see a stawberry milkshake like fluid in the radiator reservior. This will cause your transmission's 2-4 band to wear out and eventually the entire transmission will fail. When it happens, your tranny and radiator and reservior have to be replaced which will run about $7000.00 at a Hummer Dealership.

3. Idler and Pitman arms will fail after about 20, 30, or 40K+ miles. these arms are NOT designed for 35+ inch tires. They are designed for stock Suburban wheels/tires. If you have a newer H2, you will need to get the $214 Cognito kit to prevent early failure. If your warranty is out, buy the Idler and Pitman from ebaY or any PepBoys or AutoZone or Kragen and the Cognito kit. This will prevent abnormal tire wear in the long run. My dealership wants about $750 to 800 to replace just the arms.

4. I have heard of H2's front wheels falling off the truck while running.

5. H2's head lights suck. HID kits are available on ebaY for about $180 with hi/lo beams.

6. I have heard of the speedometer cluster fails after 20, 30K miles.

7. ?

So far...Only #6. Being replaced right now!!!

True. If both time and money aren't important to you, then spending the extra $4000 to $7000 on the tranny problem and a week of not having your H2 would be nothing.

However, if they are, then by simply installing an after market tranny cooler will save you both.

Yeah, I've heard that the 03 had several problems with it.......but, mine is a 04, and nothing yet "Knock on Wood"

60,524 and still strong.......

My local transmission shop fixed mine and put in heavier duty parts. The head mechanic said the stock parts are made only for an 03 Escalade-like SUV.

'03 with 80K some miles.... None of the above yet.

Did buy a 4 year extended warranty with 100K add'l miles though.

In fact, even with 80K some miles, supercharger is still sitting on the floor in my office. Not having second thoughts about it.
