Interesting that the heater core puts the hot coolant into the bottom and the return from the top. Perhaps they knew that was how to get the best heat transfer out of the fluid...push into the bottom and out the top so it uses the entire cooler and pushes out any trapped air. Same exact operation you want from a remote cooler.

Perhaps you can back up your statement with what the normal coolant temp is in the cold tank of the radiator vs trans fluid temp? HINT - the water in the cold tank of the radiator would need to be cooler than the trans fluid in order for the cooler to work. As there is a heat transfer between the trans fluid and the coolant, the result is lower trans fluid temp and raised water temp in your cold tank. Thermodynamics don't lie.

That block/head flow is wrong for LT/LS based engines though...
