46re acts like its in forward and reverse at same time

Sounds like planetary pieces. But here's the thing. That trans is a complicated piece of machinery, but the front half is generic old 727 that hundreds of people on here are very very familiar with. If the overdrive is destroyed, I say forget it; it's beyond your capabilities. BUT, I would at least drop out the pump and the two front drums for an inspection before you go with a used unknown. One step at a time. We don't make decisions prematurely that aren't even required yet. Oh, and we like pics...LOTS of pics.
