Heat-sink trans coolers. Who's got them, and how do you like them?
Old thread resuscitation!
Trying one of these, a 24” dual pass Derale. With my abnormal application, Ive running an 18”x18” FSR Racing aluminum radiator (for ground support tugs) which has a dinky lower tank trans cooler (not really sized for high horsepower vehicles) and I have been running a Derale Atomic Cool stacked plate cooler w/thermostat controlled fan. My trans temps always run about 20° or so hotter than my engine. I generally see trans temps as high as 205°-210° (maybe a touch higher) on hotter days so the Atomic Cool fan is running most of the time. Gonna try continuing running the trans fluid through the radiator tank, into the heat sink and then into the auxiliary cooler and see what differences there are. Goal would be to bypass the radiator tank but will try the three combined as it only requires one cut of the braided hose and assembly of fittings to plumb it in. Bypassing the radiator from the get go means cutting off a good bit of expensive hose to plumb and there’s no going back unless I buy the lengths I already have. Will see how it goes.
