Gearbox Issues: Is is a messed-up Syncro?

[Avalon Shotkicker]

Check your clutch master cylinder for leaks,

Leak in your master cylinder.

I sense a pattern going on (sarcasm not intended), is the clutch master cylinder expensive/hard to fix/replace?

Anyway, I will take the car to the mechanics (I have a few other [non-drivetrain] issues to sort out) and find out the problems.

Thanks everyone for your help!
