This also matches most track reports from USA and Australia, where within 2 laps on a normal track the 110c limit is exceeded for both temps.
I have driven mine on the Furka Pass in Switzerland and when climbing and accelerating hard between the hairpins, the engine temp just exceeded 110c during that drive (though not the transmission). I have also had transmission temps >110c on the road during some high-speed runs, when repeatedly accelerating up to circa 180mph then back down with traffic etc. The engine temp were fine during this as there is huge cooling airflow for the engine water/oil at high speed.

It must also depend on the ambient temperature at the point the car is used, 10-15 degrees different ambient temperature will have a huge effect on cooling. This might explain why it is more of problem in the states and OZ
