Transmission fault on my Aventador after a hot day, coincidence or not?

Went for a long drive last Friday, mostly highway, and parked up for about an hour at a mall. When I came back and started the car, the transmission fault warning came up and it refused to go into gear for a good thirty seconds. Then it sorted itself out and drove fine all the way home. It hasn't happened since but it was 45 degrees that day and the car had been sitting in direct sun. I'm wondering if heat soak can trigger these warnings or if it's a genuine fault that just happened to show up then. I've found a premium Lamborghini transmission specialist in Sharjah that I might call for a diagnostic, but I'd like some context first. Has anyone had a fault appear only in extreme heat and then never again? And does the car store these codes so they can actually see what happened, or will they just tell me they found nothing.
