Thanks guys. I did a little more research and the sub freezing temps this week in GA along with lots of rain. Short drives to work and home. I’m convinced it’s just condensation. But I will be watching closely. I drove it on 160mile road trip today 80+ mph. No issues. Cap, oil, coolant all look perfect ! So oil analysis I maybe a good idea.

Quick ? Off topic. If I do not have a magnet in my trans pan should I gel one ASAP? Thx. I noticed I didn’t have one when I did a conductor plate service
