The reason for a heat exchanger is consistent transmission operating temperature, therefore consistent performance by maintainig tolerances. Quicker warmup is also a result, as the transmission will generate very little heat by itself until the vehicle is in motion. I agree an independent system can work well, but should be regulated somehow to maintain a consistent and adequate (high enough) temp. I can say from monitoring trans fluid temps in drag racing applications, that too cold DOES hurt performance. I don't believe the heat exchanger design is strictly a financial one. My opinion, and it is just that, an opinion: The heat exchanger design works well and should be monitored and additional cooling should be added IF NEEDED. But, we can all agree that TOO MUCH heat is the enemy.
