I like the idea of leaving in the original heat exchanger and sending the oil output to a Tstat, and then either flow back to the heat exchanger if <160F for quicker warming up, or to the BMS heat exchanger in the left wheel well if above 160F for cooling.
This will solve the under cooling and overheating problems. It will also help to quickly heat up the transmission fluid by staying in line with the coolant while heating up in the winter. So we need 2 SS lines each with a connector to the stock heat exchanger, and the other ends to a Tstat, like -10AN. And then two shorter SS lines between the Tstat and the BMS heat exchanger. I’ll pay $600 - $700 to beta test.
