Last night at 5:30am my car lost it's ability to shift. I was about to leave a residential road and turn on to the main road when RPM just shot up through the roof like my clutch was burned out.
It feels like the clutch is stuck on "disengage"...car turns on and runs fine...But I can move the shifter throughout the gears without depressing the clutch pedal.
I can't remember right now if the car can turn on without pushing the pedal... |  |  | | 03-08-2009, 09:01 PM | #2 | | Senior Member Join Date: Aug 2006 Location: Central NJ Posts: 2,440 |
You might be low on brake fluid which is shared by the clutch. Also could be that your throwout bearing is stuck. Do you sit at red lights with the clutch held in? That puts your throwout bearing closer to the heat of the engine and can make the grease within "melt" out and then it would get stuck. | | | | | 03-08-2009, 11:21 PM | #3 | | Senior Member Join Date: Sep 2007 Location: asdfasdf Posts: 10,002 |

I don't think i am low on fluid because clutch pedal feels fine... | | | | | 03-09-2009, 01:24 AM | #5 | | Senior Member Join Date: Nov 2004 Location: Minneapolis Posts: 1,587 |
If your car is made in 9/1996 or later it has the clutch interlock switch, so you'd need to press the clutch pedal to start.
Most of the resistance of the clutch pedal comes from the clutch pressure plate springs. If the clutch pedal feels normal, I would assume the clutch actuation (hydraulics and pressure plate) is working properly. If that's the case, I think the only two things left are a clutch disc that is worn out, or somehow the pressure plate isn't releasing enough to clamp the clutch disc. | | | | | 03-16-2009, 12:45 AM | #6 | | Senior Member Join Date: Aug 2008 Location: Raleigh/Charlotte, NC Posts: 1,233 |

I know a little bit about cars but I am very mechanically inclined. I changed the clutch 2 years ago...starter...and slave cylinder a few months ago. Are you referring to the clutche's slave cylinder that's attached to the tranny(no sure if there are any others on the tranny)
the clutch pedal feels just fine though...I will check it though...start work on it tomorrow | | | | | 03-31-2009, 12:33 AM | #8 | | Senior Member Join Date: Jul 2006 Location: North Bay, Northern California Posts: 251 |
So started pulling my tranny out today...
oh any I'm not much of a mechanic so please correct my terminology...
anywho...as i was undoing the 6 nuts to dis-engage the drive shaft from the output spline on the tranny. I noticed that output flange was very loose...in fact after the drive shaft was disengage I was able to confirm that it wasn't connected to the tranny at all...and the collar nut that was suppose to keep it in place was also loose...
There is visible damage to the output flange I'll take some pictures...but now what..I have no idea where to go form here...I'll figure out how to post some pictures... | | | | | 03-31-2009, 01:05 AM | #9 | | Senior Member Join Date: Jul 2006 Location: North Bay, Northern California Posts: 251 |

Are the splines on the transmission damaged? If not, I don't see why you couldn't buy a new output flange, nut and a lock collar and just reinstall it. It must have been fiddled with in the past becuase it's a pretty hard thing to just fall out, espeically with the lock collar in there. #28, 29 and 30: http://www.realoem.com/bmw/showparts...19&hg=23&fg=15 | | | | |
