FYI - e trailer does have an ATF cooler made by DERALE that the MFR says is compatible with the 2018 Pilot 9 speed transmission. Check the link https://www.etrailer.com/question-289171.htm

Technically any trans cooler is compatible. You could use this one, but you will need all the correct fittings to make it work. Good luck finding the correct fittings/pipes to get it done.

Dealer told me - can't remember which one - they only install parts they get from Honda.

Sadly this is mainly caused by the flood of counterfeit parts out there. There are a lot of parts available that are supposedly genuine Honda, in a Honda bag in a Honda box, but not actually Honda. If that part fails, most customers expect Honda/Dealer to stand behind it because they think it was a genuine Honda part, but it wasn't. Creates customer service nightmares, and in some cases, possibly legal responsibility issues for the dealer.

In stock form there are no rubber hoses in the atf cooler circuits. Only two stainless pipes with a multi o ring fittings, retained by a bolt in finger. Atf hoses are added as part of the kit.

AWD Ridgelines come with a cooler that uses rubber hoses.

Yes Ridglines come with the accessory cooler as standard equipment. The op has a pilot, and was asking about a Pilot. On a PILOT there are no rubber lines, the rubber lines are added and come with the accessory cooler.
