That is a good idea and I may do that too. But, the reason is because more than half of my trips aren't where I can plug in. Also, I could run higher trans temps ALL the time, not just for faster warm up. This would provide benefits even after the car is warmed up.

A passively cooled transmission's temperature is controlled by the ambient temperature. So, anytime its less than say 115F ambient (I don't know what the OEM design criteria is), I'm actually running the trans cooler than is ideal, and thus I have more losses than I could if it was operating at a higher temp.
