Make sure it is all warmed up, taking it for a ride, or just shifting it threw the gears with foot on the brake, checking the fluid level. Keep checking and adding fluid if necessary until full.

The 7.4 quarts is for a normal drain and re-fill. Blowing the lines off may have allowed the transmission pump to pump out fluid from the torque converter as well which would result in needing more ATF.
