I did drain the torque converter too, and filled it with 7.75 quarts, which it what everything I could find said it should take, and shows full on the dipstick tool. I used shell ATF 134, and Mercedes filter, etc. The car does have somewhat high mileage but I looked at one with 380k when I was looking for this one and it still drove fine, so I figured it would be ok.

If the transmission is too worn out I am going to assume it will be a parts car when it does, this one isn't really in exceptional condition, and I haven't heard anything that makes me think rebuilding one of these transmissions will turn out well.
