This past week (April 2026) I had my three year DCT service done at a Langley BC Chevy dealer. I have a 2023 Stingray HTC with 35350 km. So the three year service included complete replacement of the DCT fluid (11 litres of tranny fluid) and a new DCT canister filter. Itemized, the fluid exchange was $999.95 plus tax while the new canister replacement was $972.75 plus tax. Just curious how this cost compares with the same three year DCT service for other C8 Stingray owners!
