Looking for help. Had this trans rebuilt. It shifted fine before (the overdrive was slipping). Has reverse, 1st second but won't go into third. New converter. Tried unhooking kickdown. I've read to reset the front band and try ziptying the kickdown lever forward.
I'll try those later today but I wanted to see if anyone has anything else.
Obviously it's filled to spec. No noises or anything to report.
