Great post @Frederic, I did face the transmission over heating issue on my very first newbie drive last week, this happened when I was stuck in a bad dune for about 20/30 mins
below is the detail of my car
3.8 L, 2014 LWB
kms done -70k
transmission oil change- Not sure as I bought this car from someone else
drive in - D mode
tyre pressure - 15 psi
i went to a garage last week for skid plates and they told me over heating tranmission is common problem with Pajeros post 2012 models, they told me a external fan would fix the problem, they are quoting me 800 Aed for this fix?
what do you advice?
