does anyone now what it is...When I shift sometimes it crunchs...but only sometimes. I check the fluid level.. its ok. What is it?? Must I change the fluid or is it the clutch? I check the clutch when I drive on in 2gear with the parkbrake on and I think the clutch is ok(car stalls). Can anyone help?? My car is an 91`GTA 305cui. Thanks for help!
