So just got the carfax on it and the transmission was serviced at 75000

So I bought the truck about 11/2 yrs ago, trans has not given me any trouble. Truck has 154miles in it was going to change the transmission fluid, but haven’t cuz I wanted to get all parts needed before starting . I bought Mobil 1 ULV blue label oil. Worked great on my Escalade when it starts to shutter

Hello everyone, I a proud owner of a 2020 Z71 Trail Boss LT. Lately I’ve noticed trans temp going over 220. My 5.3 is paired with a 10L80 transmission and seems to have an internal thermal bypass valve. Been looking for a solution can’t find one. Anybody no a good fix for this. I’d really appreciate the info thanks.
