I'll bump an old thread. I don't understand why Honda calls the hockey puck a warmer......My observance is tranny fluid temp is very, very slow to reach the same temp as engine coolant, so how can they say it is a warmer? Slowly, tranny fluid temp continues to rise and will rise well above engine coolant temp. I have observed 219F tranny fluid temp when engine coolant temp is 183F.
A gentleman member in New Zealand post that Honda dealerships there are required to install a Honda auxiliary stacked plate type tranny cooler whenever they install a trailer hitch. Honda CVTs over there, and elsewhere I presume, have the external tranny fluid tubes specifically for a auxiliary tranny cooler install. USA CVTs do not have the provision allowing for a auxiliary cooler install. BUMMER!
The days of tranny fluid being circulated to a heat exchanger located in the cold tank of the engine coolant radiator are over (at Honda) and have been for a while. arn::confused2:
