2013 Honda CRV, does anyone know the flow of the transmission oil through the ATF Warmer. Does it come from the bottom of the transmission through the filter to the ATF warmer and back to the transmission? Or does it come from the transmission to the warmer then from the warmer to filter back to transmission? I know I could feel the hoses for heat, but the one under the air filter is almost impossible to get a hold of. Any help would be great.

So I took my IR gun and checked the temp on the hoses and here are my results:

Hose coming out of back or transmission to the filter - 134F
Hose from filter to ATF Warmer - 130F
From ATF Warmer to front of Transmission - 104F

Also I did tow with it on the weekend and checked after the trip as I was curious on temps.

Hose coming out of back or transmission to the filter - 173F
Hose from filter to ATF Warmer - 173F
From ATF Warmer to front of Transmission - 134F

Only towing about 150kms each way, but need to travel over two mountains on the way. Trailer is dry weight 1500lbs, but with everything added it could be about 1700lbs.

That's why I am here as I don't know. So is the flow going from the front of the transmission to the warmer and then from the warmer to filter and then back into transmission? I guess my question is should I have the trans cooler installed to save my transmission in the long run.
