I'm going to be towing a small popup with my 2013 CRV, and was considering putting a transmission cooler on it. However, after poking my nose around the engine bay, for the life of me I can't find the lines where the transmission fluid enters or exits the radiator. All I can find are the two large coolant lines. Does this thing cool the transmission fluid in the radiator? There's obviously no external transmission cooler on it, just a radiator for the air conditioning system. Does it have some sort of heat exchanger in the transmission maybe?
