Toyota A340E Torque converter

I have an '02 Toyota Sequoia with an A340E auto trans, is the stator within the torque converter supposed to spin easily in both directions for this particular transmission/application? I have other non-lock up converters(Ford C6) and the stator within these torque converters will only spin freely in one direction and lock if spun in the other direction. No auto parts store here locally has one "on the shelf" for me to check. Please advise. Thank you in advance, Todd Tedder
