Okay. What do I do now?
Well, after a lot of debate and advice I decided to stay with my current TV and see how it would do. My TV: 2007 Silverado 1500, Quad Cab Short bed. Engine: 5.3 V8 Trans: 4 speed auto with o...

Okay. To answer some questions. I had overdrive locked out and was running mostly in 4th. When my trans temp hit 190, I shifted down to 3rd. I never got over 55 MPH. My trans temp was climbing very fast and I pulled over and let it cool down to 170 before heading home. There was no wind today, so that was not an issue. It was 100 degree and I am sure the temp on the asphalt was super hot and that was making it hard for the trans cooler to keep the trans oil temp down. My tow/haul system is stock from GM, so I am sure it is installed correctly.
Okay, I just took a 30 mile round trip test drive tonight to Denny's. It is a slight downgrade all the way there and I did 60MPH. My trans temp started at 110 got to 168 on the way there. It took us about an hour to eat. On the way back my trans temp started at 150 and got to 179.6. It stayed at 60MPH and it is a slow climb almost all the way. The outside temp was 85 degrees during this test.
So the problem appears to be that my transmission cooling system cannot compete with Texas summer heat while towing a trailer.
So now I have to weigh my options. Here are my options
1. I can either restrict my towing to early morning and nighttime only, which will limit my daily travel distance significantly.
2. I can spend money to change the rear gears to a much lower ratio and maybe add an additional trans cooler, which will significantly reduce my empty fuel economy and slightly increase my towing economy.
3. Trade up to a larger TV.
