Does my clutch fork look broken?
 
To you guys? Or damaged in anyway? I unbolted the slave, and put a borescope in there as best as I could.

Oh, car is a 96 lt4

Help? If it's dumb question, sorry. I'm new to this.

It's not a dumb question - I just don't think anyone has ever had a look at these parts from this POV before. From what I can see, I don't think it's broken. It looks okay at the pivot stud end to me, although I really can't see much at the throwout bearing end.

Does the clutch work?

I'll post a vid of the car at idle, while pushing the clutch pedal as well. It does get quiet when I push the clutch pedal. But i'd consider the sound to be more of a "whirr"

Yes it does. Just trying to chase down rough shifting problems.

Out of curiosity, does anyone know if that is too much play on the fork?
Where I talk about the slave being bent in the video, I meant to say "clutch fork isn't broken".

No, I think that's pretty normal from what I remember. It has to have a little up/down play or else it would always be putting pressure on the throwout bearing. The side-to-side play is fine, too. I really doubt any shifting roughness will be caused from a problem inside the bell housing. It's more likely to be from a hydraulic system that isn't fully bled and therefore isn't letting the clutch fully disengage, or possibly bad synchros in the gearbox.

The old trans fluid(May 2019), didn't have any metal chunks in it. Nor did the fill or drain plug, so I hope my scynchros are good. This never ends, yet the clutch is firm. Whole clutch hydraulic system is new. Has a recently rebuilt oem slave and 4 month old master made by Wagner. Really, the only thing I can do next is install the rebuilt oem master.
