2007 Suburban Z71 towing question

Hey guys
I'm new to towing a camper. We have a 24' tt dry weight 4500#. I just found out we have the gt4 (3.73) gear ratio on our tv.

Going to a higher numeric diff ratio (two if 4x4) will increase the
power (torque) to the pavement...therefore higher MTWR (Max Tow
Weight Rating) of the TV

With the new platform and the close ratio automatic has 0.6:1 double
OD

We have put a transmission cooler on the vehicle to cool it down but it still runs over 250 on the interstate. On our last trip I got a little more comfortable with towing the camper and I got up to 70 mph. After about 15 miles the transmission warning came on.

Says either or both you are at or over the ratings of your TV...or that
the heat management system is marginal or going south...

I was wondering if anyone might know of anything else I might try. We have looked at 3/4 ton trucks but we cannot find one that fits our needs and budget. Lol

Yup...next higher class TV would help or solve

I thought about replacing the rear gears with the 4.10 but didn't know if that would create a whole new set of problems.
Any suggestions would be greatly appreciated.
