Lately I've been having a lot of trouble shifting into first, second, third, and fourth. I did a search and came up with a few options: Syncros, clutch master cylinder (recently been replace), slave cylinder, or clutch.

Pretty much I cant get a smooth shift in, the clutch engages right away (about an inch off the floor with the pedal), and now I am hearing a clicking noice that seems to increase with the rotation of the wheels (only under acceleration, not at cruising or deceleration). The clicking noice might be a completely different problem since my car has 140,000.

I want to figure this out myself and not go to a shop, but if it comes down to that I guess I'll have to.
