Under normal use, the transmission temp should never be that high. There is definitely an issue that needs to be addressed.
Either the front radiator/heat exchanger for the transmission cooler circuit has been punctured by road debris, or one or both of the pumps on that circuit have failed. Either way, you need to get the dealer to address it NOW. Do not wait. And if the drive there is anything more than a few miles, get them to tow the car to the dealer.

In the meantime, check the coolant reservoir that is on top of the engine (front and center when you open the hood). It should have pink-colored coolant in it. You should easily be able to see the coolant through the side of the reservoir. If it's dry, you have a leak in the system. If so, check the front-center radiator so see if it is wet. It'll be pretty obvious if/when you see it. If it's wet, your radiator has been punctured by road debris and needs to be replaced.

If it is a puncture in the front radiator, it more than likely won't be covered under warranty. Of all the people on here that have had it happen and of the few others I've heard about, only one person had it covered under warranty (sorry to rub it in, but it was me). It's not considered a part defect but instead outside road damage. It's the same as if you get a rock chip in your windshield or a paint chip on your front bumper.

As for when it happened to me, there was an obvious puncture in the radiator. I could see the wetness on two vane rows of the radiator, an empty coolant reservoir, a puddle under the car, and the radiator basically peeing on my foot when I poured distilled water into the reservoir. I even have the chunk of asphalt that poked the hole (it had formed to the radiator, and I scraped it off when everything had cooled down).

The OP never mentioned a leak, but with a large puncture and/or a long drive, the reservoir/circuit could have completely drained without signs of a leak. You'll see wetness on the radiator, but the typical puddle under the car might not happen since the coolant is long gone.

Punctured heat exchanger most likely won’t be covered under warranty.
I have heard of one member being covered but in the US but here in Australia not covered from what I’ve heard, not in my case and many others with punctured heat exchangers.
Good luck to the OP, no one wants to see their car over heat... I replaced my 3 front facing heat exchangers from ARE Cooling after getting a puncture aposed to replacing with the fragile AMG items.
Drew designed and fabricated these for me and are available as direct bolt on replacement with no modification.

Update: rock hit the the radiator which caused the leaking not covered under warranty. Waiting on Mercedes to see if they will good will it. If not 1700 bill

Damn, that sucks. My transmission temperature went up higher than normal as well, and started shifting rough.
But then it maxed out at 85 deg. C and didn't go higher.
The next day, it went back up to 85 C, but wasn't shifting rough anymore.

I just had a radiator & coolant pump replaced due to rock damage. Was not covered under warranty. Insurance did cover under comprehensive since it was caused by a flying rock. These radiators need better protection.

The front mounted intercooler assemblies on the 19 onwards C63's are even more exposed than the pre update cars, so there's more chance of debris caused damage.

instead of me paying 1700 Mercedes agrees to pay the labor. So I’d owe 540...
