      My friend Doug owns a tranny shop and I do some work for him every
in a while when he gets the Dodge diesel pickups in for repairs. 
    From what I have seen, a cooler is a good idea on anything, if you use
for towing or not, as hot as newer cars run, many with thermostats that
open until nearly 200 degrees, the supposed cooler in the radiator turns
more of a heater than a cooler. I have put coolers in a lot of things but 
never a CRV, might be tough to find the proper fittings to get it plumbed
without using that cheap rubber hose crap.
    The synthetic fluid is good, but will still need to be changed at
intervals, many people change their engine oil religiously, but forget about

their trans and diff until they blow up, then complain that they should have

lasted longer. On my stuff, if I don't tow with it, I change the gear boxes 
every 50 thousand miles, if I tow with it, I cut that interval in half.
Towing is 
hard on stuff, but not just because of the weight, the wind gets down
the trailer and the tow vehicle and pushes on the trailer just like on the 
front of your car, and big boxy trailers don't have very good aerodynamics,
that makes your vehicle work a lot harder.
