As a new C8 Corvette owner, GM provides you with a free oil change as well as a free filter change for your dual-clutch transmission during your first 12 months of ownership. And while the Owner’s Manual service page says the DCT filter should be performed at 7500 miles, it’s still something that you will want to swap out during that free oil change even if you don’t have that many miles on the car.
A friend of ours recently told us that he went in for an oil change at 5,000 miles as his oil life indicator said it had nearly been 12 months, but he skipped the DCT filter change as it’s called for 7500 miles. A couple months later, that DCT filter change ran him a little over $300 because it performed after the 1-year mark. You only have the one free service offering from GM so wait until your oil life monitor indicates the need for the first service or schedule a service call for your Corvette just prior to one year.
Here is why GM is recommending and even offering to do the first DCT filter change during the first year of ownership.
The Corvette Mechanic Paul Koerner, a GM World Class Technician for Key Chevrolet in Middletown, CT shared a video on his Facebook page this week showing the lid of the DCT canister filter from a Corvette Stingray with about 1,500 miles on the odometer. Even with the low miles, we can see those deposits that have accumulated on the cover assembly.
Paul tells us these deposits are being filtered by the DCT’s canister filter during the DCT’s break-in procedure, and the residue left behind will also need to be cleaned before the lid assembly is reattached to the car. Once the initial DCT filter change has been done, you won’t need to do it again for another 22,500 miles.
