tranny probably slips on the hot+175hp when towing heavy, and empty it doesn't slip. and on the mild 60hp setting it doesn't slip and it adds a nice boost in power so it really it optimized on the towing setting. unless its a 2010-13 dodge or you did an after market valvebody in the transmission and bumped up the line pressure so it doesn't slip.
