Hello blee62, try to avoid starting duplicate threads of the same problem. It will get disorganised for you. The person on the forum that is familiar with the 580B is Phil in Canada. You need to describe what problems your having with your tranny, give as much detail as you can and maybe Phil can help you out. He's usually here early in the morning and signs off before 9 at night. Try to give as much info as you can for him to noodle through.
