Yes I clean the pan well, everytime.

I have 2 line coming out of the tranny and going into the radiator. But 1 seems to have a break in it for some reason and someone pieced them together with a hose. Unless that is where the tranny cooler goes. There is a u shaped line i front of the radiator, It goes to nothing also.
