Very interesting your car has a 1956 transmission installed, which is no small feat--I can tell because of the aluminum housing and the speedometer drive. It would take someone very conversant with Packards and parts interchange to do that swap.

When it sits all of the fluid comes out?? You mean all three gallons? If it is coming out of the vent that you pictured it is because the fluid level is too high and when the car sits and the torque convertor drains back overnight it reaches the vent. With the conversion of your car to the 56 trans there is a good chance that the dipstick does not register properly.

Per one of the service counselors, there is a way to get an accurate fluid level even when the dipstick is suspect. There is a brass plug at the back of the transmission housing just above the pan, facing directly to the rear. Remove it right after shutting off the engine and let it drain down. Reinstall the plug and then add one quart of fluid. That is the correct full level and you can take a file and mark your dipstick accurately.

Then even if your convertor drains back when sitting, the fluid level should still not reach the vent and run out.
