Having the hydraulic system flush only be required for the first DCT filter change could make sense but, so far, there isn't much evidence to support that. Some people have said that their dealer told them it is no longer necessary but a Corvette tech than participates in this forum has chimed in saying it is still required. The procedure that the tech follows would have to be tied to the VIN for it to work this way since the DCT hydraulic system flush procedure is part of the DCT filter change procedure.

I don't see where he said money is an issue? Smart folks plan. I look at prices and costs all the time. Assuming he is new to Corvette his question is very reasonable.
Clarify please, did you pay $700 at the first 7500 mile service, which should be free, or the second 15,000 service which is my expectation?

I did the first oil change for free at about the 4k mark on the one year anniversary along with the trans oil change (also free).

Trans oil change? At 4K miles? The DCT fluid change isn’t required until 45,000 miles, or 3 years. But if your dealer did for free, I guess why not!

I’m thinking he may have meant to say DCT filter change. If not, he got a heck of a good deal if the dealership paid for the trans fluid change.

Changed engine oil, changed engine oil filter, changed HVAC filter, changed air filter.
Checked a bunch of stuff and that's it. $700.

I know this in the pdf service manual purchased from eBay but that section is sort of generic. It will be interesting to see what dealers actually do when they follow the DCT fluid change procedure on the computer. Similar to how the hydraulic system flush isn't part of the DCT filter change in the eBay manual it may be that the internal filter change isn't part of the DCT fluid change when the tech is following the procedure on the computer screen.
I'm really interested in knowing if the internal filter changeout is part if the official DCT fluid change.

It's not clear to us exactly what you had done for free at 4,000 miles. You said trans oil, but I don't think that happened. I think they changed the trans oil FILTER at 4,000 miles. You got the one free service GM offers. If they charged you $700 for an oil change and a couple of filters, you need to find a new dealer.

Simple answer.... The routine service on a C8 will be something on the order of 2 to 3 times that of a C7 or C6 Corvette. Even though it's just a Chevy, the mid engine coupled with the DCT significantly complicate service routines. Let's not even talk about mechanical repairs down the road.....
Oh, you're Ferrari maintenance isn't "free." You paid for it in the several hundred thousand dollar cost of the car. You could pay a heck of a lot of maintenance on the C8 and never equal the overall cost of a Ferrari.

The ebay manual is nothing but screen prints from the GM online service manual. The reason the hydraulic flush isn't in there is because GM added it after they started noticing DCT problems. If the oil pan drop and filter clean isn't in the online manual, it means GM removed it for some reason.

OP... as others said if you want to save some money, pay for your 1st service, and take your second service as your free one.

I didn't see anything in his question that said he was worried about anything. Sounded to me like he was just curious and just asked a simple question. One that you couldn't bother to answer.... but yet you, with all your wisdom thought he should reevaluate his purchase?? Who do you think you are? You dont know anything about him or his finances. FWIW, we do have horses and a barn, but still nice to have an idea going into a new purchase.

I agree my post was a bit assuming and abrupt however was brought about by a conversation with a young fellow this past week who had reached out to me for advice who was really stretching it financially to afford a C8. I should not have tied the Ops thread to that conversation.
