I was surprised at the 195 reading too. Semi-hard driving was never full throttle or exceeding 50mph but I was heavy on the loud pedal for 12 miles with approx. 14 stop lights and 5 stop signs along the way. I have a gauge and cooler on my 98 chevy fullsize van that I tow a 24ft travel trailer in 100 degree weather up 6% grades usually with the A/C on. It usually never exceeds 190 with the trailer (160no trailer) but if I drive it hard in town with NO trailer it will run 190-200. Stop and go traffic, or stop light to stop light is what heats them up even more than pulling long hills at speed with a heavy load. I regulary pull I-80 over the Sierra's (7200ft elevation change) and can never get the tranny hot like in town
