ATF was changed about 15K miles ago, with Mits ATF, and levels are good.
Once the engine warmed up the warning lights stopped, and only happened during a period that local temps never got above freezing. I am wondering if a sensor got covered with ice that finally got melted off. I have had the car out Friday, and Sat and there is no sign of the problem.


There have been other instances of water affecting the AT temp light, so you are probably OK.
