Thanks for all the responses.. wow. I just spoke to my GM Shop manager here where I work and he states that GM models have a breaking point for it's transmission..
average towing should happen to be anywhere within 190 to 220 degrees and you should only show concern if it hits the 250 degree mark as it will then start to get interesting.. and should pull over and park .. do not shut off the vehicle.. as it will actually take longer to cool. then when the temp hit a safer level continue on your way. If you see the temps of 250 or close to, this is when you may want to look at a larger transmission cooler. As he states that a over cold Transmission is just as bad as a super hot one.
So no raise of alarm and I was told just to keep an eye on it for reference.
Thanks everyone for your replies.. you were very helpful.
