Heat-sink trans coolers. Who's got them, and how do you like them?

You should stay with what you think is best, fits your application and what you know from your actual experiences with use. That’s good.

I don’t know what heat sink you’re referring to. The one I have has internal and external fins the entire length, and is mounted in a location where it will see fan blade airflow at stops, as well as airflow through the radiator (yes....it will be hotter air...) but will actually see good ambient temp airflow from underneath when rolling. Got lots of air there with my setup. YRMV. Yeah, we know wtf we’re doing round here :thankyou:
