if at operating temp fluid barely touches dipstick than you are low by at least 1 liter. but make sure you are inserting the dipstick tool all the way to the bottom, sometimes you think you have it all the way in, but actually it;s not. so check it 2-3 times. also do you have the car running and tranny in park (p) on leveled surface when you checked it?
if you checked it correctly and fluid barely touches the bottom of dipstick tube then i would add 1 bottle, get fluid to 80C and then check again and fill til you have it close to max level at 80C on dipstick. also make sure you don't have a leak, check around connector plug or cooling lines.
