Get analog or digital thermometer , they r like $30 bucks on the inter net. Unless you're have a problem it should be between 180F to 210F. Towing a heavy load maybe 215-220F+ or -

Yes, he was asking for a way of checking the oil temperature which is mandatory during filling or checking the level of the transmission fluid.

I pointed him to Inpa that can do it with a direct readout, but since he has GT1, I pointed him to the menu where GT1 deals with 'oil level check'.
GT1 is not just a 'reading' tool, it guides you through a procedure to check something or repair something, and in the procedure to check the oil level for the transmission, the temperature is taken into account.
