I have a 99 328 w/77K miles. It seems to have developed a dragging clutch. It doesn't shift as smoothly as it used to with more resistance than normal getting it into gear. And when stopped, if I depress the clutch and then put it into first gear I hear what sounds like a clunk from the diff as the slack is taken up. This make me think the clutch is not disengaging completely. Also, if I park on a slope and leave the car in gear to help hold the car, then apply the handbrake and press the clutch in, it's not easy to get the car out of gear and I can feel the car lurch forward slightly, again indicating that the clutch isn't disengaging completely. Any thoughts? It's been flushed recently but there was no discernible change. I'm using Redline D4 ATF in the transmission.
