M50d-r1 Scratching noise

Hello, first post. 98 Ranger 4.0 4x4 196000 miles. My transmission has started making a scratching noise in any gear (including Neutral). Here is a video.

Does it have any oil in it?

 

[bndpoper]

yes, 2.8 quarts of fresh Mercon.

Did it happen after you changed the fluid?

It had been sitting for almost a year with a bad slave. It was doing it some before it was parked, but not as bad. I pulled the cover while it was out, and did not see anything wrong, or hear anything working it by hand.

Sounded to me like the noise went away for a bit, did you push the clutch pedal in? I wouldn't be real worried about the transmission itself making that noise, sounds more like a throwout bearing or pilot bearing noise... I'm assuming you replaced the slave cylinder recently?
