i have an 08 cobalt ls sedan. its a 5 speed. i notice sometimes the transmission will grind a bit when shifting to 3rd or 4th even with the clutch all the way down. the times i noticed it the most was when i would first start out driving like when the car wasn't totally warmed up. once the car is warmed up it seems to be fine. is this a big problem? should i go and tell the dealer about it? thanx
