Transmission temperature question
I have never towed anything with an automatic, but I know the temperature is critical. I will be towing with a 2009 Tahoe next weekend. At what temperature should I be concerned? Other than keeping...

If I pulled over every time my transmission reached 200 I would never get anywhere. My trans typically runs 85-90 degrees above ambient air temperature- unloaded- but running fairly fast.
With a load on hot days trans temps often get into the 225-230 range- which is no big deal. The allison can run at that temp all day long.
On a lighter duty trans, I would do my best to keep temps under 220- They hold less fluid and generally have much smaller coolers so it can get too hot fast.
When in doubt, travel at night or plan your grades for early morning. Have pulled the Baker grade when the big thermometer read 126 and when its read 60- ambient air temp makes a giant difference!
