After market transmission cooler advice

I have a 14 model toyota tundra with the 4.6 liter engine, I should have gone with the 5.7 but I got a good deal on the truck and can't afford to take a loss on it yet... This is my delima, the truck is rated for 7200 lbs tow capacity (not 10k like the dealer told me, i know now thats only the 5.7 model) and my new camper weighs 6700 lbs (pretty much maxed out). Last weekend I went on a five hours trip and it pulled great there and back but when I got back to my campsite and was backing it in the trans fluid overheating light came on. My question is has anyone run in to a similar situation or can anyone recommend a good aftermarket external transmission cooler? Thanks in advance! 

TexasRedNeck:
Heat kills transmission. You are on the right track with an external cooler.  I'd service the trans and add a cooler and a real trans temp gauge. I don't know your line routing or set up but it shouldn't be hard. Get on big enough to keep it no higher than about 220. Run synthetic if you can and a thermostatically controlled unit would be preferable if you see any weather below freezing very often. Take some pics and let's see what you are working with.

B&M 70266 and an Earls 501 as an example. The Earls has ports for a temp gauge too.

I'll try to figure out how to post pics. For some reason it's easier to post download pics than it is ones I take... Does Tapatalk make that easier?

TexasRedNeck:
from the tapatalk app in your phone you can snap pics and load via the app.
