That was my thought too. I couldn't figure how it got out in the first place unless the shop that gave the tranny a once-over did it when seals were replaced but I don't know if they touched the shaft seal. They were only looking for leaks to fix. What's driving me crazy is that after I fooled with it for a couple of hours by adjusting the cable it worked for a while then reverted to form and lost "D". Or I shift it briskly a few times and move in & out of Park and it works. I put 10 miles on it the last time and kickdown & everything worked perfect...next night no go. Any chance the manual lever is bent just enough to allow it to slip in & out? I am really dreading dropping pan as the headers have to drop to give access. PITA!
