I think mine took 6 quarts. I took a tip from ericthecarguy (does great youtube vehicle repair videos). I knew that it would take a minimum of 4 quarts, so that's what I put in. When I was able to start it up, with the jeep sitting level, I let it get to operating temp, put it in neutral, put on the parking brake (or chock the wheels), and checked the level. I kept adding and checking until it was full.
There's no way it'll take 9.6 liters, that's over 10 quarts. Maybe if the trans is bone dry, including the torque converter and fluid cooler. But for just a filter change, it's 5 or 6 quarts.
