Torque converters do not have a fixed stall. When the input shaft is fixed and the pump is spinning and when both are spinning change the actual point of "lock up". Ideally you would want a converter to stall at the max RPM on the starting line but that would be called a clutch. The converter "fall back" on gear changes is important also as a slight RPM flare actually increases acceleration.
