Our 5AT requires 6 quarts and I believe it's supposed to be changed every 30 K miles, you're a little late!
Now you're out of warranty I'd buy 6 quarts of Red Line synthetic AT fluid since you've neglected your trans it's time to treat it right. This will make your trans shift smoother too....G/L

OP what I would do is buy 8 quarts, drain the pan, and refill with 3 1/2 quarts. Drive 50-100 miles and repeat the process. Give the car about 1-2000 miles and repeat. That way you don't shock the tranny all at once with new fluid. I don't think the tranny has been hurt unless you track your car but check your fluid ASAP. If it is dark or brown and smells burnt, you probably need to ignore my first advice and take it to the dealer for a complete flush and fill.
The tranny fluid is Nissan S-Matic, it replaced the J-Matic and is the only transmission fluid recommended for our engines.

Actually the transmission holds 10 3/4 quarts. The 30,000 and 60,000 mile services call for a drain and fill which takes about 3 1/2 quarts to do.
