Not entirely sure if you’re asking for help or not. The ford guide is confusing because they say the same thing like 4 times slightly differently.
im assuming you know how to drop the pan and replace the filter. Measure the fluid you removed as it’s a good starting point. I drained ~7 quarts
once it’s back together and you have put fluid back in get the car up to temp while it’s on a lift or jackstands. Use a scanner to make sure the trans is at temp (91c - 102c)
climb under the car while it’s idleing and in park, remove the dipstick and check it’s at the top of the dipstick. Add or remove fluid as necessary. Be careful your cat will be hot as fuck and right next to the dipstick
