Yeah but I don't like the idea of the TC not locking up, even for around the town driving. It defeats the purpose, to some extent, since more heat will be generated. And that heat is lost energy which hits your gas mileage. From what I have been told, the most important thing is to make sure the transmission is not shifting constantly and driving in 3rd does that. I also understand that some people believe that driving in lower gears, at higher RPMs also puts less stress on some tranny components like the bearings. So that's a good thing. But I still don't like that the TC doesn't lock up. Would be nice to get a TCU upgrade that allows the TC to lock up in power mode, at all speeds.
