clutch/tranny grind.. car stalls
 

1. on idle when the car is warmed up and I: turn the steering wheel, press the brakes, turn headlights on, or put my foot on the clutch, the idle drops.. it does it a little bit when i turn the headlights on, a little bit more with brakes, a little bit more when i turn the wheel, and a LOT to the point where the car is about to stall when i depress the clutch. anybody else have this problem?

2. if i let off the gas to slow down, a scraping/grinding noise comes from the transmission area. and if i down shift from 3rd to 2nd it gets louder. if i slow down and put my foot on the clutch and stop the car either stalls or shakes like its about to. any help? thanks

anybody?
