Also, it ain't warm in texas all that much right now, so colder than 60 degree days play hell on summer tires. Sounds to me that the TC is doing what it is supposed to be doing.
As a reference, from a stop making a turn on cold pavement slowly with my summer rear tires on, my TC kicks in at less than 10-15mph regardless of drive mode. And I mean on like a 20-30 degree F day.
