I want to start by saying I am no trans guy. I just rebuilt my 401 nailhead and I thought I would go ahead and put new filter and fluid in my st300 trans. I also emptied all the fluid out of the converter. I was told that i didn't need to add fluid to the converter that the pump in the trans would fill it up. Well I went to move the gs yesterday and the trans kept slipping. I then hear a dry sound in the trans or converter not sure. but she will not move when I put here in gear. can I get some help? Joe
