Smoke from dipstick tube

[Colby Roberts]

I have a 2015 silverado. Was doing a routine check and removed my transmission dipstick. Fluid is nice and red looks almost brand new and is also full. I did have transmission work done about 3 months ago and on average driving 60 - 80 mph my transmission temp is between 165 and 190 but will get hotter on hot days. Highest its gotten was 205 but i was going quick due to an emergency. Anyway I noticed a light smoke coming from the dipstick tube. Is this normal?

Condensation can build up in the transmission and it's turning it into water vapor.
