And you're basing this on what? Are you claiming that grit left inside a part is a GM design issue? If you think it's that big of a POS, then sell your car and buy the perfect car. Your opinion is based on ignorance. BTW, by definition that is a lack of knowledge.

Well squabbling over gm quality is pointlessl. We either own one of these cars or are getting one. There does seem to be some problems and with cars such as Honda Acura transmissions eventually they all had problems. Everyone became aware and resale values were affected. Thats why if we could all figure out the best extended warranty that might cover all theses cel codes, sensors, diagnosis it would be a great…

Best warranty for the first 5yr/60k: The GM limited warranty extension.
Best service contract for after 5yr/60k: Chevrolet Platinum Protection Plan.
Now, whether any of these are worth the money you pay for them is a different story...

I think you are correct about GM limited warranty extension is the best. My problem like you is that I am in California. Where it is not available. However I am buying back east where you can purchase. The dealer will sell me the 2 year extension for 2300$ . He says California dealers will not honor but I am not convinced. Also am fairly close to Nevada so I plan on verifying if I can bring the car to them. Anyone else working on this.? To me 2300$ is expensive but how much is a new trans troubleshooted and installed?

Basically, you'd be betting $2300 that you're going to have a problem in years 4 & 5 that wouldn't be covered by the powertrain warranty and the repair cost would exceed $2300. And the fewer miles you put on the car in those years the less likely that is going to happen.

I purchased an extended warranty at time of delivery because of two unknowns for me. One was Global B electrical architecture and the second was the DCT. No matter how much testing is done new designs go through a shake down period. In 2014 ZF came out with a 9 speed in several cars and they dropped like flies. Mine passed the "snap ring not seated" test and was given the blessing as a "good one" all the way up to 62,000 miles when it dropped dead and had to be replaced. I usually don't buy extended warranties, but I also look at the variables before making the call.

The limited warranty extension only bridges what would not be covered by the powertrain warranty in years 4 & 5. In the case where the DCT had a problem that required replacement within the first 5 years it would be covered under the powertrain warranty at no cost to you whether or not you had purchased the warranty extension.

I paid $1400 for it and it was more than worth $700 per year in years 4/5 for piece of mind that if it breaks GM fixes it.....period.....

Yes, but i don't want any dealer to try to wiggle out of a repair related to a problem somewhere in the driveline or engine in years 4/5 saying that whatever the problem is is "not covered under the powertrain warranty" (i.e., something electronic related to the powertrain but not considered part of it). I like the verbiage in the ELW that reads Should a warranty repair be needed after 36,000 miles, the entire vehicle is warranted for repairs, including parts and labor, to correct defects in materials or workmanship, excluding routine maintenance.

Then you are also saying the GM designed A8 with all its class action law suits has nothing to due with GM or it’s lack of ability to design a reliable transmission? Same goes for the GM designed DCT IMO. I don’t go through life with a bag over my head. The Corvette DCT is seemingly heading in the same direction as the A8 unfortunately.

So before the debate on gm stuff starts- I was making some good progress on figuring out best extended warranty coverage for invested dollars.
i think spending additional money and thought on this is a good idea.
We listen to transmission problem posts-generally it seems to be a long and drawn out process. Check engine lites, back and forth to the dealer, flushes, valve bodies, more electronic trouble shooting,solenoids, contamination and sometime a new trans. So if your warranty is up how much will this. Cost? I think it would be af good thing to know….
