Okay, if you do just a little bit of searching on this site, you will find the do it yourself instructions for filling the transmission. Some people get really upset when someone tells them that the answer for there question is here and they just have to look for it. Even so, I am unwilling to do the ten minute search for you. Below is a link to the factory instructions for filling the transmission, but if you search here, you will find a slightly easier way to do it.
