some cars have a torque converter with a lockup clutch. When the two halves of the torque converter get up to speed, this clutch locks them together, eliminating the slippage and improving efficiency.

You can floor it at any time, locked or not. I believe that if you go WOT on any stock 700R4/4L60/4L60e it will unlock right away and downshift (depending on what gear you were in and how fast you were going).
