The torque converter will fill when you start the engine. Add maybe 3/4 of the specified amount of ATF, start the engine and let it idle. Then it's a matter of checking and filling, checking and filling...until the proper level is reached.
My tranny takes nearly 2 gallons of ATF. I add 6 quarts, then run the engine and top it up in 1/4-1/3 qt increaments.
