So you're still going to control the minimum trans temps for winter?

Yeah, the thermostat opens at 140.  Instead of running through my radiator and the condenser, it will just run through its own cooler anytime the temp hits 140.

They went unregulated for decades. Pepper has the 70 C TBV but it is never open in the winter. Still it runs a bit warmer then as fluid isn't circulating the radiator. But just a little warmer. Not enough to ever open the stat.
