Warning long post, but wanted to get to the bottom of what might be the cause of this problem and if anyone else had experienced something similar in their 600LTs.
This is a new car, heavily MSO specced, ordered from factory. I've never had this problem with my 570S either on the road or track before. Also I'm a long term track enthusiast so I know what I'm doing with the car, I'm not shifting randomly and having the car reject shifts. I've driven some cars at similar caliber and never experienced something like this; my car is ordered new, I didn't expect there to be issues like this at all.
Problem: When upshifting in more spirited drives (Manual, Sport Mode), the car doesn't shift up to the next gear and instead downshifts (because of this and the speed it happens at, it drives the RPM all the way up to redline).
TLDR: can refer to videos directly.

In the videos, I've successfully replicated Gear 3 attempts. During testing I ensured my foot was on the accelerator with no sudden lift off (though I tested even if I lifted off the car shifted normally), and because we have rocker shift paddles, it's impossible for me to pull downshift while upshifting.
Also this is happening during really pretty low intensity spirited driving for this car's capabilities, I am not really pushing it as I'm not on a track and also I prefer to be gentle with my cars. The problems occurred at least once every time I was driving the car, the videos are recorded in the same afternoon during a 1 1/2 hour period of spirited driving.
Please chime in if anyone know what might be the cause of this or ran into similar issues. I've contacted my dealer but haven't heard back yet. I suspect it is software related but last time I was in the shop my dealer told me it was updated to latest software.

- Happens most often in gear 3 around 6k RPM. Sometimes it flashes to 4 then drop straight down to 2, revving the RPMs like crazy. Sometimes it doesn't shift up and stays in 3. Sometimes it doesn't shift up and downshifts to 2. (Refer Videos)
- Happens most often as you are just starting to do spirited drives after warming everything up, but I've had it happen later on in the drive as well just less often.
- So far I only had it happen in Manual, Sport Mode. I didn't have the chance to fully test the problem in Manual, Track Mode, but in the short time I did I haven't had the problem happen.
- Happened twice in First Gear also around 6k RPM, car doesn't shift up as supposed to and instead stays in First Gear and the revs hang. I wasn't able to replicate the First Gear problem when I am recording the test drives, also due to limited road conditions for launching, but the problem did happen twice without launch control, just normal acceleration and shifting at around 6k.
- Happens completely at random during spirited driving. Best bet is 3rd shifting to 4th at 6k. On average happens 3-5 times in a 1hr drive. (Note: this is just spirited driving after car is warm, not pushing hard on the car, shifting at redline, etc.)
- After the problem happens, it rejects upshift commands for about a sec, the best way I found when the problem occurs is to not touch anything and just brake to let the revs drop down and slow the car until it is normal again.

- Video 1: You can see after I pulled the upshift paddle, (if you play it slowly) it flashed to 4th gear then dropped straight down into 2nd, causing it to rev crazy high.
- Video 2: In 1st attempt, it didn't upshift when I pulled the paddle and instead stayed in the same gear. In 2nd attempt, it didn't shift up at all and instead downshifted also sending RPMs high. 3rd attempt was normal. 4th attempt, if you play slowly, the car flashed up 4th gear and didn't stay, went back to 3rd then down straight to 2nd.
