Vortex flow is indeed at its maximum at full stall, as this is when the fluid flow within the torque converter is most turbulent, which Technician A correctly states. Technician B is also correct in stating that vortex flow is at a minimum during the coupling phase, as this is when the turbine and impeller speeds begin to match, leading to a reduction in turbulence and thus a decrease in vortex flow.
