If the trans, including the torque converter is completely empty it will take up to 11 quarts, some a little more or less. If it's just the pan that's empty it will be around 4-5, again might be a little more or less. Just keep slowly adding and checking the dipstick. Also go through each gear for about 15 seconds with your foot on the brake to get fluid through the entire valve body. And check it when it is at operating temp, not cold.

but can I start the car and run it that long for it to heat up? I stated the car up couple of times but I do not want to let it run too long because am afriad it will burn up the transmission.. is it ok to run the engine until normal operation temperature so I can check the transmission?

Thanks kris

Fill the trans with fluid up to the first small hole or hash mark while cold. As it warms up it will expand to the full mark.
You could cause damage to the Pump or the Converter running it with low fluid. Eight to nine Quarts to fill a dry 400.
