With the converter locked, the engine rpm has to drop rapidly at the shift. The engine (with converter mass) has a lot of momentum and since it can not drop instantaneously, something has "to give":
1. With luck, only the frictions in the trans will slip and wear out prematurely.
2. With less luck, a yoke, driveshaft, axle or trans part will break catastrophically.
