When the car is cold everything runs smoothly. But after I drive around for maybe 5 minutes I hear a high pitched squeaking noise if I don't have the clutch engaged. Wehn I push in the clutch a little it doesn't squeak anymore. Also when I get the car up to around 2000rpms, i hear a rattlish sound. Once I get past 2000 that stops. Its coming from somewhere in my bellhousing/tranny area. Throwout bearing????
