transmission squeal/whine

I have a 2002 taco 3.4l v6 with 160k on it. Just had the clutch done a couple weeks ago. I started noticing a squeal, like a belt squeal, a couple days ago. It does it in neutral, 1st, 2nd, 3rd, 4th, and 5th. If I rest my foot on the clutch it goes away. It only does it with the clutch pedal all the way out. I crawled under it this morning and it is very pronounced around the slave cylinder/shift fork area. If I grab the shift fork and wiggle it then it changes pitches or goes away. Anybody have any ideas? I've been searching the internet for days and haven't come up with much. Thanks

 

Sounds like a TOB (throw out bearing)

 

I hope it's not the tob. It was replaced with the clutch. Bought the clutch kit from trail gear. I thought the tob would make noise if the clutch was engaged not released?
