If your transmission is like mine, you'll drain roughly 7 qts from the pan and torque converter. (Sometimes it's a good idea to measure what is drained out to estimate the fill.) After you button everything back up, don't refill the entire charge! The manual indicates that you refill with 4 qts, then start the engine and refill the remaining charge.

I recommend refilling it about a quart low, then run the car until the transmission is warmed up (10 miles minimum), check the level, and top off to the full mark.
