2005 CRV 5 speed auto.
I have a small utility trailer, rated for 2000 lbs, but I'll never be
pulling that much weight.
I'm travelling approx 400 km / 250 mi round trip. Several times this summer.

Should I install a transmission cooler?
Is a transmission cooler necessary?

If so, what size is a good one.
Etrailer has a list of coolers, I was thinking the model 41019 would do the
trick if needed.

All comments appreciated, you can even make fun of me for asking if you
like.
