My '05 (same 48RE trans as the OP's '06) can lock the TC in every gear including first... at any engine RPM and any wheel speed.

You don't have a stock transmission like 99% of the pickups have. Your built transmission has likely been upgraded in most areas allowing it to lockup in first. I know they don't lockup in first in stock form. Thats one of the reasons the transmissions heat up at very low speeds when pulling hard is because the torque converter is unlocked. Yours also has to unlock at slow speeds or it would stall the engine, just like having a manual transmission truck and not pushing the clutch in when coming to a stop.
