So, I rented a Pontiac Grand Prix yesterday. I was fooling with the little information display on the dash and it had a few interesting displays. -Battery voltage -Engine hours -Oil life remaining -Transmission Fluid temp. I was really surprised by the ATF fluid temp. I was bummed that there was no engine oil temp reading. Can it be programmed to display the engine oi temp? While driving in 70-105F heat the ATF temp varied from 190 to 228F. While on the flats on the freeway it would hover around 200F, then when climbing a hill on the freeway it would rise 20-30F pretty quickly. Interesting.
