What is the GM Maintenance Scheduled for this trans?, last I looked it was drain fluid/change filter every 100K Miles. That is all GM calls for. You tell people to do this at 50K Miles, Who are you to tell people they should ignore the GM Maintenance Schedule. Per GM there is no required maintenance before 100K Miles. Yet every failure has occurred at less than 100K Miles. The only time GM says to do this sooner is when the vehicle us used in severe service (Police, Taxi ect.)

 

severe service interval is 50 000. Driving in the southern states where ambient temp is 90*, that is 1 severe service condition. Every car should follow the severe schedule as every one will, at times, meet that criteria.
Car makers want to advertise there vehicles as maintenance free, they're not.

fluid wears out. depth filters do not filter 100%, debris from break-in and assembly and normal wear and tear circulate in fluid suspension. The first fluid change will remove 80% of the debris that circulates through a trans in its lifetime. If your only gonna do one trans fluid change; do the first one. ATRA states that 80% of trans failures are attributed to lack of maintenance. people refuse these and other services. just wait to see what happens when the new direct injection engines don't get emission services.


If I had a shudder in my trans and it was near the service interval, I'd exchange the entire 16L capacity...but no...just keep driving it.

 

It does not matter if your advice is right or wrong, it matters what GM puts in writing. If a costumer complains of shuddering transmission and it has 95,000 on it, a dealer can not say that it was a maintenance issue, nor can they deny coverage based on that, they must honor what is stated in the manual.

GM's Definition of Severe Service:

Mainly driven in heavy city traffic
in hot weather.
. Mainly driven in hilly or
mountainous terrain.
. Frequently towing a trailer.
. Used for high speed or
competitive driving.
. Used for taxi, police, or delivery
service.

Just because a vehicle is driven in the south with 90 degree weather does not constitute severe service. I live in Michigan, it goes into the 90's in the summer, is this then classified as severe service, I think not.

Weather you are right or wrong is irrelevant, It may be great marketing for GM but a dealership must support what GM puts in writing and can not deny a claim for anything less. It is not you or any dealers job to define severe service if GM has already stated what it is, and the dealer must back that. The dealers are representatives of GM and must honor what GM states. If GM states 100K Miles for a trans fluid change, then it is their job to manufacture a trans and a fluid that will survive that interval. If data in the field shows otherwise, it is the dealers job to convince GM that the maintenance schedule is unrealistic, and have it changed in print for future vehicles. but it should never be dumped in the customers lap.

 

Wrong again.
This is right out of a 2007 impala owners manual:
In heavy city traffic where the outside temperature regularly reaches 90°F (32°C) or higher.

If you are implying that I am saying this applies to only people who live in hot southern climates, you sir, are a simpleton.

Any mechanic or dealership that refuses valid warranty work is a hack in my opinion. I do not know the dealers side of the story, just grumpy customer. As a customer, if you think you have a problem that is not being addressed, get a 2nd opinion. Do I have to problem solve everything for you guys? How do you get though everyday life?

 

Not Wrong, Not everybody drives in heavy city traffic on a regular basis in 90+ weather.

If you are going to quote something, do not take it out of context. The complete quote from the 2007 Owners Manual is:

Change automatic transaxle fluid and filter if the
vehicle is mainly driven under one or more of
these conditions:
− In heavy city traffic where the outside
temperature regularly reaches 90°F (32°C)
or higher.
− In hilly or mountainous terrain.
− When doing frequent trailer towing.
− Uses such as found in taxi, police, or delivery service.

 

I sound like an ahole? Reread your posts mr. Butthurt internet tough guy. Did i call you names? Childish. Oh, and FYI tranny flush and fluid change was done at 40k miles.....gm says it should be done at 50k. And its my wifes car to shuttle my kids around so I sincerely doubt she drives like an ahole.
Dont be so butthurt over people complaining about ur precious gm. Last I checked its a free country u dont like it dont respond. Grow up! Oh and happy easter everyone!

 

Oh , and btw....I own a hyundai already and have had TONS of warranty work done including replacing a manual trans cuz my clutch grenaded because of a design flaw and they didnt even blink an eye. Replaced no questions asked and i've brought my hyundai in before for "symptons" that i described and even tho they couldn't duplicate it, they still replaced what they felt COULD be the problem (MAF and FUEL INJECTORS replaced because i described a slight problem i was having and you know what? The symptons went away, THAT'S customer service......so stop talking about things you have no idea about. ASSumptions are the mothers of all f*ck ups.

 

your story changes to cater whatever requirement you feel you must meet. Sounds like your Hyundai is a quality vehicle.

 

maybe its a coincidence that the ending of the powertrain mileage warranty ends when that trans fluid service is due.

If you want to buy a $40 000 car and change the trans fluid once every 8 years go for it. Don't service your brakes either...its not in the maintence schedule. Wait until 100 000 to change your spark plugs and never do emission services. If you live in a rust belt don't undercoat it....all good ideas.

 

tech2,

You are part of GM's problem, not part of the solution.
