Hi, I know the torque converter on these locks up but it seems extremely 'light' on mine and almost impossible to validate as any small depression on the gas causes the revs to move up out of proportion to the speed. if it is a slight fast depression of gas, it comes out of lock up, and on coast

I can confirm that it does lock, I can mostly notice it @ around or >60 mph, I can go in cruise and the revs drop 100-150 rpm when it locks.

Does anyone have any specifics as to the conditions it does lock? I understand it should also lock in other gears?
