I believe you're backwards there 74vette. Preferred way is to go through the auxiliary cooler first and then through the vehicle radiator. Thus if the auxiliary cooler supercools the fluid, the radiator will warm it up some. The engine thermostat makes sure the coolant coming out of the engine is 195* so after the radiator cools it down some the temperature at the trans cooler element is almost the perfect temp for the transmission.
Say What!!!!! You want your tranny fluid to run as cool as possible. Tranny, Rad, extra cooler, back to the tranny. If you start with 180 degree transmission fluid in the pan you will destroy it on a good along pull.
I monitor tranny fluid in two places. In the pan and at the output line. Temp in the pan barely moves the needle most of the time. But will get to around 170 in really hot SW weather on a good pull. Get it around 235 in the pan and you are in trouble. The output line reacts quickly to stop and go traffic or mountain pass pulls. Heat destroys tranny fluid, and destroyed tranny fluid destroys trannies!!! I run Amsoil tranny fluid.
