Since it's been getting really cold here, I've noticed every once in awhile when I'm coming to a stop and putting the car into first it'll start to grind a little as if I didn't have the clutch all the way in. That's what I thought the problem was at first because normally only push down far enough to shift gears. But then it happened when the clutch was pushed to the floor. It doesn't happened when I'm stopped just every once in awhile when I'm slowing down. Anyone know why it's doing that?
