So I removed the pan on my 727 and found quite a bit of metal shavings on the pan. This is a rebuilt unit with 9000 miles on it. Now the lever for the low reverse band is loose am I mistaken but isn't there suposed to be tension on that lever? If I pull it down it just stays there. I was just going to do a filter change and was going to adjust the bands while I was at it. And was a little shocked when I saw the amount of metal. The car never slipped and had every gear. I had it rebuilt previously because it lost reverse. Any advice?
