Got a 2023 Corvette Stingray? Here's What Track Rats Need to Know Before Adding Two Quarts to the DCT

When Chevrolet first introduced the 2020 Corvette Stingray, the owner’s manual called for adding an additional two quarts of fluid to the dual-clutch transmission for those who were taking their cars to the track. In 2024, the Corvette Stingray received a redesigned pan on the transmission and adding the two quarts was no longer required.

However, that change with the transmission case was a running production update which happened during the 2023 model year without the owner’s manual being updated. So unsuspecting owners reading the manual may think they need to add the additional fluid before heading to the track when it’s actually not needed.

And that’s where our friends Mike Furman and the MidEngine Corvette Forum come in, for they have sleuthed out the exact VIN for 2023 Stingrays where the production changeover occurred:

Thanks to Mike Furman@Criswell, we sleuthed this out today as to when the Stingray’s DCTs were changed during the 2023 model year. I had known it was between mid June and early-ish July but we never had precise info until Mike and I delved into this. He called one of his insider friends and learned that on June 23, 2023 was the introduction of the revised transfer case, with its among other changes, moving the internal oil pick up point to a more efficient location. This allows the SR’s going to the track effective with that revised DCT no longer needing to add in the two extra quarts of DCT fluid.

As to which exact VIN was the revised DCT introduced? It was introduced on Stingray # P5137263.

So for the regular 2023 Stingrays, the break point comes at sequence #37263. But what about the 70th Anniversary Editions?

After seeing that the MECF was on the hunt for this info, Corvette’s Product Marketing Manager Harlan Charles responded and tells John at the MECF that the DCT pan break point for the 70th Anniversary Editions was sequence #3905.

So how many of these new cases were delivered in 2023? Chevrolet built a combined 47,372 Stingrays for the 2023 model year with 42,793 regular Stingrays and 4,579 70th Anniversary Stingray models. Based on these VIN break points, there are 5,530 Stingrays and 674 70th Anniversary Stingrays with the updated DCT.

Thanks again to the Mike Furman and John at the MECF for sharing this information!

  3. I just flush the hydraulic fluid in my clutch reservoir using the ranger method before going to the track.

  4. So what happens if you add an extra 2 quarts to one of the newer series DCTs? Any damage covered by the warranty if not mentioned in the Owners Manual, or if the shop doesn’t check the production numbers before adding or not adding 2 quarts?

  6. I’m not sure I agree with your date. I was at the factory watching mine be built that day and my VIN is a couple thousand away from the one in your article.
