Looks like its similar to the P2855 (Clutch Charge Pressure) but for the other clutch. I had the same thing occur for P2855, car operated fine and the light went away. Per the Service Manual procedures, Dealer will reset codes and perform some tests and corrective actions. First they will reset codes and see if it comes back. If it does, then they will perform solenoid cleaning procedure then retest. Then check trans fluid level, then retest. Then Change trans filter, and retest. Then change valve body and retest. If all these fail and light is still on, they would replace the transmission.
One note for all of you new to the Corvette world......
The C6 was the first generation where Chevrolet started installing many more electronics in the Corvette to improve performance. It had approximately 20 microprocessors in it and was a parasitic drain on the battery. I owned a 09 C6 from November 2019 until March 2021 and kept it on a battery maintainer every time I parked it. It wasn't my daily driver. Prior to buying that car I had a 15 C7 and never kept it on a battery maintainer. The C7 has 70 microprocessors in it. I had that car from May 2015 - May 2019 and it never drained the battery. It wasn't my daily driver either. I don't know why the C8 seems to be such an issue with the battery.

If you had. a 2005 C6 with a 6 speed standard and did not shift to reverse when the car was shut down, the battery would go dead over night. Corrected in 2006 and beyond.

Don't I know it, I had one. At least once per summer it did that. They finally came out with an update for the BCM that fixed it, but it took a while until they figured it out.
I started using a battery tender when I bought a C6 in November 2019. I owned three Corvettes before the C6 and never kept them on tenders - even my 15 C7 which I had for four years. The C6 is a parasitic drain on batteries.
I have an '11 C6Z/Z07 3LZ with a 3 year old battery as one of my sports cars and it will sit for a month w/o a tender and starts every time. Had an '06 C6Z before it and it was the same. Guess I'm just lucky.
The C8 rear view mirror with camera function is incredible. It takes a little getting used to having to focus closer, feels a bit odd, but the visibility it gives you vs the tiny little bit of tunnel vision through the glass is fantastic.
Right up until the point that it stops working. I consider my vehicle to still be in the break-in period since I haven't hit 1500mi yet.
My mirror started to flicker. Started showing some brief black horizontal lines. Then the screen would flash black rapidly, but still show a picture. Then all of a sudden I get a full blue screen with a NO CAMERA and a little hand icon telling me to flip the visor up.
Since the screen appears to still be active, I suspect the part that failed was my camera or something between the mirror processor and the rear camera. It was working fine and then within the span of about 30 minutes from noticing the glitches it went to full useless.
If I stop the car and shut everything off, wait for the interior electronics to shut off, then re-enter the car the mirror/camera works again, but only for a couple minutes before BLUE SCREEN OF DEATH occurs. Top left corner is NO CAMERA icon Middle icon (sorry blurry) is a picture of a hand flipping the visor lever.
Some of you blokes who are finding glitches in your hyper computerized/chip 2/3LT cars might want to consider this car is a sports-car first. There are some nice Cadillac model with high tech things you should consider.
It's a sports car with a WICKED blind spot problem. Have you driven one?
The electronic mirror is a necessity, IMHO. When it fails, your lane changes are quite a bit more risky.
Maybe you don't care about little things like bikers on the road....
Yeah, I found myself accelerating quite a bit prior to lane changes to make sure there is nobody there. I hope this excuse works well to get me out of a ticket.
My 2 week old C8 with 538 miles, battery died after trying to apply an update. Worse was that the driver's door lock accepted the key which turned but did not open door which is needed to access the frunk. Had to call tow service. I directed his attention to the lever on the inside floor. Using a long probe, he was able to access and succeeded. But weather strip is now dented. Hopefully, it will get back in shape. We had to use two jump boxes and the car fired up. Drove to Chevy. They replaced battery, and applied updates. They will spend the next two days working on the driver's door lock. I'm probably the first C8 to have this issue. To all of you with C8s, TEST YOUR DRIVER'S SIDE KEY LOCK. MAKE SURE IT WORKS. Catch a wave at Sandy Beach, Oahu, Hawaii.

If these problems persists to the point of recalls, too many warranty claims or threatened class action suits, Chev must consider dumping all the silly millennials working to turn a good sports car into some sort of XBox game.

Had that at about 2000 miles. Camera replaced by dealer, easy replacement. Problem solved.

I think I read somewhere that it has over 170!
The battery charger must use an enormous amount of energy figuring out how to keep it from turning on.
Putting this vehicle constantly on a battery tender will be a pain popping the frunk and might lead to wear on the frunk latch. You would think the power management would be smart enough to completely power off most of the 170 ECU's when parked / sleeping.
Was wondering if it makes sense to install a cigarette lighter plug (or some other sort of quick disconnect plug, perhaps one with a protective flap or something) somewhere under the front fascia/bumper to make it MUCH easier to connect the battery tender? (well, so long as you have no trouble bending over)

“I've had mine most of 2021.It's not perfect in terms of rear view, but the standard mirrors are adequate with some neck turning. I've owned worse. If you go fast enough in the left lane on the freeway, it's not a big problem.

Permitmefour, why are your knickers in a twist? If a “bloke” is having legit trouble with his car and wants input from other “blokes” to see if others have the same trouble, isn’t this the right place to ask the question? Shaming “blokes” for wanting their cars’ functions to work as designed is not very forum-friendly.
