Has anyone been able to confIrm if this new layout has in fact occurred for year 2024 production as the article suggests?

Yes, it actually was implemented late 2023 manufacturing year

Found this information if it’s credible would affect some MY2023 builds”…July 17th 2023 and vin# 7263 are when the new case not new transmission was changed. The new case does not need the 2 extra quarts. The internals are the same. I was told this face to face with Harlan Charles.”

“Harlan represents Chevrolet marketing and the Corvette customer with the Corvette Engineering team for the current and future Corvettes. His job is to make sure product decisions support making Corvette customers happy.”

If this VIN is correct; good to know I have new and improved casing.

Mine was made on 17th (7296)

Took delivery Friday evening drove it a few times over the weekend (I dont think I could even call it spirted) maybe got 90km on the car and the transmission started acting up I was getting 'rear axle system is off' on the dash display I also noticed sometimes when I stopped completely the car would show it was in second gear still and would start in second gear, then came the CEL I got the diagnostics report from Onstar which showed 2 codes P0700 and P2818 by no surprise is related to the transmission. Almost 5 months to deliver after build date due to railyard fun I got 2 days of enjoyment which was indeed awesome. Car is getting looked at tomorrow im hoping it gets sorted in time that i can still drive it a bit this season I want the bugs worked out now so I dont have to miss any driving in the next season. This car may be cursed stay tuned.

Hopefully another reflash/ update will get you sorted out. It seems GM's route is updates, then valvebody replacement, and finally transmission replacement if all else fails.

Got the car back today was told transmission was reprogrammed so I took it for a burn tonight and the transmission seemed alright going up through the gears but down shifting not so smooth especially dropping to 3 gear in auto mode seemed to kinda clunk into 3rd. By the end of the drive I had 'rear axle system is off' and engine light back on . Ive read others with the same codes needing valve body replacement or even tranny swap what a headache, on a side note I also noticed when I installed a set of jacking pucks tonight before I headed out that the dealer installed the track only cooling ducts on the rear . to be continued....

When I popped my car up on the hoist the first time, I found the dealer had done the same thing. One was also busted in half from street driving. Must have clipped it somewhere.

I would be curious to know if the change was made in your user manual. (Don't add extra fluid for track use)

I will check the physical book; only ever read the online version

UPDATE: Tech said transmission would only pass test 1 out of every 5 times tested and new valve body is needed and on order heres the kicker part is on national back order so driving season likely over. Saga continues........
