I don't think you would want to take the fluid out of the torque converter anyway. If you drained the torque converter and didn't remove the whole tranny how does it get back in there. I watch Horsepower TV on Saturdays on Spike (formerly TNN) and they say you should never have that thing dry when you start it. I don't even know if you could drain it. Besides how would you really know for sure it's been refilled?
