Climbing a long, steep grade at 65 MPH and roughly 3/4 throttle makes it surge. I do not know if the converter unlocks for that. If it does, I don't hear or feel it. I'm pretty sure it just grinds up in it in direct.

Rolling heavy into the throttle at 50 mph unlocks the converter and it surges the whole way on up to 80 MPH whether you keep the throttle steady or go ahead and floor it after you reach 60 MPH (flooring below 55 mph downshifts to low...don't do that). Again, I cannot tell if or when the converter locks at those speeds.
