Explain your logic..... Just as you basically have a the hotter flow water line coming from the water pump going into the radiator and cooled down from the radiator out back to the cylinder head. You basically have the same going on in the hockey puck. 4 lines in the puck and 4 lines in a radiator application. Water in, water out, trans oil in, trans oil out. Then you have the hot side of the tranny line going into the side or lower radiator for a common radiator car/truck application and is EITHER cooled or heated depending upon if the car was just started or long term running and if the weather in 10 degs of winter or 90 of summer. Here too, you have a choice of what " transmission line" to use on the return line of the hockey puck oil exit just as you would if the RAV4 was using a radiator for cooling or heating the trans fluid. So yes there is a difference where you put the finned trans cooler in the "flow" scheme.
If you are hauling a boat or trailer the time the hot pan fluid is in the dinky puck or even a radiator may not bring down the temp to engine water temp. So doing it in the right order makes sense, just as it does when adding and external cooler with a radiator based trans cooler flow scheme.
