I have a 2003 Mustang 3.8L V6 that does a really loud squeal when the clutch is pushed in, however when the clutch is all the way out it doesn't make any noise. As well it only happens when I'm in lower gears like 1 or 2 and it never happens when I'm in the higher gears. The car only has 69k miles on it and i'm pretty new to fixing cars so I have no idea what it could be, maybe the throw out bearing?
Here's a video of it:
