I got the transmission May of last year. I had it installed and it was slipping from the start. I called to have it returned but they gave me the run around. Well after 1 year with it in the garage I got some cash saved up and took it back to another shop. We found used parts in a rebuilt case. that is why the want you to return it. They don't want anyone to see what we found. I found some one else with the same issue.
