I have a 2019 Avenir which is a very competent car. My second Enclave since I gave my first, a 2012, to daughter to haul children. There are four gauges on the dash of my 2019 and the leftmost one, next to the tach, measures some kind of oil temp. Is it engine or transmission? No one I have talked to, including the dealer, have any idea. It runs right around 200 degrees F. Thanks for anyone who provides the answer.
