I am wondering how much fluid is in the torque converter. I am getting ready to do my first trans service on this car and first ever. Any tricks or issues I should know about?

I am planning on using Mobil1 since the dealer does not carry fluid for this application, pulling the plug and draining the pan, doing the TC if there is enough in there to warrent the effort, pulling the pan and replacing the filters - anything else?
