thanks, that helps alot. btw nice to meet you. I'm still having some trouble finding out exactly what tranny I have. any help? I think it is a 4l60e, not sure. that one pointed me to advanced chart, but I am really new here and could not find anything to that effect. any help would be great. in the mean time I will update my profile. thanks again.
