GM WONT REPAIR MY TRANSMISSION

[Maj.Drew]

OK, SO now I am pissed!!!! I had a Magnason Supercharger installed on my 2005 H2, and put about 7000 miles on it. Last week, my transmission wouldnt shift into second. Took it to my local H2 dealer who said 2nd and 4th grears are gone.

So now the good part. GM wont fix it, and wants Magnason to pay for it. So far I have been without my H2 for 10 days, and no one will fix it.

This sucks!!!! GM sucks.....

Any ideas anyone.... I have a call into Hummer customer service.

This is bull****.

[KenP]

I'm glad things turned out well for you. Too bad it took so long. BTW, no complaints about my trans.

[tower]

Buddy, you are f***ed. Even though, in all probability at 7k miles, the supercharger is not the cause of your tranny problems, GM is under no obligation to cover this.


Suggestion: See if you can get your dealer to split the cost or provide a “manager'
s discretionary discount.” Otherwise, bite the bullet and work some O.T.

[SOCRATES]

So I would assume that a lift would compromise the suspension warrany of course, as well as the transmission? If so, I hope I don't have any tranny problems. Yikes!

When you installed your supercharger did you buy the $200.00 power train warranty from Magna charger? If you did then Magna Charger should cover it. </div></BLOCKQUOTE>

Kdio is correct. I just finished reading my Magna charger warranty and everything power train related is covered for 3 years from the date of install. Also if your dealer did the install your covered for an added year. This might be dependent on how much business you've done with them and your attitude toward the whole problem. Either way had you purchased the $200 additional coverage you would be covered. I've also looked at what I got in writing from my dealer and because they sold me the unit, and installed it they are covering the rig bumper to bumper for one additional year after the magna charger warranty ends for parts, I'll have to pay for the labor if something does go wrong.

I hate to admit that you do get overcharged using the dealers services but this is a case of you get what you paid for. Sorry to here you are having trouble.

My transfer case went out on my '03 H2 and they covered everything, even gave me an extended wauranty to cover the transfer case...

I wanted to put a supercharger on it later and they said in no uncertain terms that anything connected to the driveline would not be covered in the wauranty.

... so I bought my H1

One other piece of advice for when you have your trans rebuilt. If they replace your 2-4 servo(which is what actuates your 2-4 band) with a Corvette servo, you'll get a much firmer more positive shift. That would help make the band more durable. The only downside is a firmer shift when just cruising around town, but your trans will hold up better. Remember, when your trans is actually shifting, things are slipping, and that is bad for the trans. The faster and harder you can make it shift, the easier it is on the trans.

[KenP]

My first thought is Who did the install? If the dealer did it, the trans should be covered under warranty. Remember I had trouble getting Mag to pay up for a problem, too. And it was their part that failed.

If the dealer didn't do it then I'm not sure there is any help out there. I'm concerned for you on this.

Ok.. so here is the latest from GM customer service - THEY WILL NOT WARRANTY THE TRANSMISSON AS I HAVE INSTALLED AN AFTERMARKET SUPERCHARGER. THEY STATE THERE IS NOTHING DEFECTIVE WITH THEIR TRANSMISSION.

KENP... ANY ADVICE??? </div></BLOCKQUOTE>

Bull. On my first H2, the 2 & 4 also went out- and I didn't have a supercharger. Tell them to step up.

[Hummertech]

Sorry man, but I'll be completely honest with you. I work at a Hummer dealership, and if it was my call, I would absolutely not cover it either. You've got to understand something. When you put a supercharger on your engine, you are running a lot more horsepower and torque through the transmission. When they design these vehicles, they design the trans to be able to hold up to the horsepower for the enigne they are putting in. Horsepower breaks parts. Thats an old hot rodding rule. No exception here. Now other people here are right. We have seen 2-4 band failures, but the 3-4 clutch failure is more common than that.
Picture this in your mind. You're got your foot mashed to the floor, and you're taking off fast. When that trans that goes to shift into second, you've got a drum inside that trans spinning very fast, and now you've got a flimsy band that is suppossed to come out and hold this drum, while all of this horsepower and torque is still being applied to it. I can understand why it burned up.
Once again sorry, this is just the stuff you encounter when you start modifing your vehicle like this. The transmissions in these are good trans's, but in my opinion, maybe a little light duty for the size of this truck. When you apply all that horsepower, and possibly with some hard driving. That trans will be toast. Your best bet is either drive easier with the supercharger, have your trans rebuilt by a performance shop that may be able to make it more durable, or find a way to get a 4l80e trans put in there.

I have spoken to my dealership about superchargers, lifts, etc. and they will honor factory warranties, but it costs a considerable amount of money. (This was touched on earlier in this thread.) I am looking at about $8,000 USD for a 6" BulletProof suspension lift, about $16,000 USD for a 12" BulletProof suspension lift, and about $8,000 USD for a MagnaCharger supercharger, including headers, exhaust, and installion. I do not think the supercharger is a bad deal, if it maintains the factory warranty. (I spent a fortune to get the extended warranty to begin with, so I do not want to lose that.) From my observations, I am one of the poorest people in the forums here, but I still stand by "you get what you pay for," and am willing to wait longer in order to do it right.

Check your S/C certification for manufacturer compliance. In order for the SEMA act to apply, the component has to pass the manufacturer's maximum specification. If it doesn't say approved for use by GM and will not void your warranty, it most certainly will. This has to do with powertrain components which increase the hp/torque. Don't blame GM for covering its own ass. Warranty costs are high as it is and ALL manufacturers are cracking down on modifications. Most people don't think about the whole picture when they add power, that the u-joints might snap, the trans might burn up, that the axles are too small. If you're going to blame someone, blame yourself for short-sightedness.

Listen, I love my H2 and all and would love to put a SC in it and put a lift and 40" tires on it but, at the end of the day, I remember that the H2 in its stock form borders on the breaking point with regards to the stock setup-tires and wheels, engine, transmission, etc... The thing is just too damn heavy and just wasn't engineered to have any more horsepower or bigger tires. Now people here may disagree with me, but I am already seeing after only 14K miles on my stock H2 that the transmission is starting to lag, the engine doesn't have quite the same pep that it once did and the steering and suspension is getting all "gimpy"-if you know what I mean. Of course I don't really care since I have it on a Smartbuy and will just give it back to GM and get me an H1. </div></BLOCKQUOTE>

FWIW, I agree. The H2 is heavy and underpowered. But it's still fun to own one!

[Longhorn]

Yeah, I hate to hear it and I am sympathetic but I have to agree with Hummertech.

I think this should be common sense. If they had voided the Warranty on your AC, thats a different story but its fairly easy to see the logic in place here.

If you add 150 horsepower and 200lbs of torque, somethings bound to give and its not due to a design flaw.

Yeah I have to agree.. I mean why should GM be responsible for YOUR mods? Duh..

[KenP]

I should also note that my dealer stepped up and really worked hard for me. Maybe yours can do the same.

If you have to pay for the repair, consider taking it to a trans shop and have heavy duty parts put in. The cost will be about the same anyway. Better safe than sorry.

Again, I hope the dealer installed it for you.

[NJ H2]

Have the Tranny done by some PROS and make a Small Claims Law Suit against your Dealer and Magna. If you win you get your $ back. Courts seem to favor the customer and since you only have 7000 miles in the charger you might just win!

[GeorgeSSSS]

Boar-Ral:

I don't know how it works in Canada, but I have seen deals in the U.S. where the initial warranty comes from the factory and the extension comes from a third party insurance company. If that is the case for you, it seems to me you should check both contracts because the third party wouldn't necessarily be bound by the factory's promise to cover a supercharged vehicle.

Hope this helps you avoid problems,

[Maj.Drew]

Hey, parts guy... Dont worry about a thing.... I researched it well and new the risks... but for an OE to completely absolve themselves from any responsibility on things that have "patter failures" that is another thing.

I am fortunate enough to be here in Detroit, and be very close to the auto industry. Actually I have even heard of a potential "silent recall" on H2 transmissions.

So I mean.. come on at least 50/50.

But hell, why you would make a personal comment about me in a forum is beyond my comprehension - You dont know anything about be, and trust me when I say I have and do take full responsibiliity for all of my actions and decisions.

Go toke another one!

For everyone else on here... the posting was to vent my frustrations, and also to educate others thinking about a SC and other mods.

Information is power.
