This is a good install. The number 1 enemy of transmissions during towing is heat and the coolers go a long way to preserving the transmission.
Something some people add is a thermostat that will bypass the aux cooler until until it's needed.
For me, my new to me 2008 F150 came with out the factory tow package. It has a standard Radiator and a standard transmission cooler. The radiator is about 1 inch thick and the HD radiator is about 1 1/4 thick but has more cooling fins per square inch. The transmission cooler is a four row cooler vs the HD cooler which is a 9 row unit.
I'm resolved to installing the bigger radiator when it's time for some heavier towing again but I'm not sure if I will install the factory 9 row transmission cooler or go with a two cooler system like you have.
Thanks for sharing your clean install, it makes me think more about what I want to do.
Thanks!
