I have a bit of a time sensitive question. I took the 2023 C8 in for service and it is due for its DCT service (11,850km). The car had an oil change at 5,500kn which did not include the DCT service (as it was not needed then). The service department is saying that for the DCT service to be “free” it would have had to be done at the initial service. My understanding is that this is no longer correct. They are committing to look into this for me but I was wondering if anyone has any documentation that supports this no longer being the case.
I found a bulletin showing updates service info for MY2024 but nothing on the 2023. Hoping some here who is more knowledgeable may be able to point me in the right direction.
I will get the service done either way but would like to save the $$ if possible. Thanks!

. I would be VERY wary of the opinions you get from GM Customer Care. Taking much of anything they say for fact will cause you all kinds of serious “fun” when you & your C8 arrive at your safe & effective Service Dept. For 2022- 2024 cars in most cases the dealers choose (tried hard) to push the two services on owners as one, where they said the one free canister filter had to be burned at the time of the initial free oil change service. As owners we soon learned and adjusted for those antics. With MY23 I am not aware of the 2023 cars benefiting from a further year extension beyond the manufacturer’s 2 year period on the warranty covered DCT filter change. However, as stated in the previous post 2024/25’s do receive that extra year now taking the factory covered maintenance to 3 years. BUT, the customer will be declined warranty coverage and you will be paying out of pocket (reads your own pesos) on the DCT filter change. It matters not when within the 3 year period you show up at your favorite service depot unless the car has at least the minimum 11,265 kms. Maybe tell them GM Customer Care said…
. Now, might you find a dealer who isn’t up to speed on this and tries to run the warranty code, sure there are countless threads about clueless service department representatives. Furthermore, I too have read online articles saying that 2024+ C8’s owners have 3 years or 7500 miles whichever comes first 
but none are GM Bulletins. So really, this cost saving GM bait & switch where “you get something but they took something” is only going to frustrate garage queen owners that can not do the DCT service themselves. Finally, perhaps a newer GM Service Bulletin has replaced 24-NA-081 issued 04/24 (I am not aware of one so please post away for all of us) spells all of this out and provides a helpful Q&A section.
