If you drain both the torque converter and the transmission pan and it will probably take about 9 quarts give or take. You need to fill through the dipstick tube. Put in about 6qts of the fluid, start the car, and go through all the gears with your foot on the brake. Then add 1 quart at a time repeating the procedure until you have reached the correct amount of fluid. Make sure you are on level ground while doing this. After you're done, take the car for a drive to get everything warmed up to normal operating temperature. Then check the fluid again. The fluid level is very sensitive. Make sure you get it between the high and low marks. It could only be half a quart that takes you above or below the high and low marks. So be very careful.

Patience is a virtue when doing this process. Also, consider getting a new filter for the transmission. There are a number of manufacturers that sell kits that come with both the filter in the pan gasket. Other than being messy, it's actually a pretty easy job to do.
