For those guys who tow heavy (over 12,000lbs) what is your trans temp usually at? I towed a 40 ft gooseneck last night about 500 miles round trip and when i came home loaded my temp gauge was reading like 220-230 degrees!
I had never seen it this high, so this morning I went through over the trans cooler and the lines and couldn't find anything wrong. I went ahead and changed my fluid and both spin on and internal filters out of fear I burned it up pretty good. The truck has 24,000 miles on it so i was not to far off from having to do it anyway, but do you guys usually get that hot when towing heavy or do i have some sort of cooling issue?
