Use a hand pump and pump the fluid out of the transmission through the fill tube. You will only be able to get around 25% of the fluid out but so you will need to repeat this procedure at least 3 more times. When you pump the fluid out, put back exactly the same amount of fluid you removed. Do not overfill. This is the only way to do it without removing something.
