I own a 1999, v6, manual, 3800 series. My clutch pedal gets stuck whenever I depress to switch gears. Please help!

Same thing happened to me. I am talking to a dellership right now. It might have something to do with the slave clinder.

This could be caused by a hydraulic fluid loss situation. If not, then check the fore-aft movement of the crankshaft when the clutch is depressed. I have had experience on another make vehicle. The sympthom is that the clutch works normally with the engine off, but with the engine on, especially on an uphill incline, the clutch pedal sticks to the floor. In this case the clutch will not disengage. It is caused by wear on the thrust bearings on the crankshaft. Good luck!
