Recently, my car could not shift into gear when it was turned on, off it shifts fine. The car has a hydraulic clutch. So I thought it might be the clutch master cylinder, and replaced it, and that was not the case, then there was a small leak in the slave cylinder, which I replaced it. I was speed shifting it, then it got stuck in 4th gear. So it is in 4th gear, no matter if the clutch pedal is in or not. The shifter, flops between 3rd and 4th also. The dealer said to bleed the air better out of the clutch system. This problem came on fast, not gradual. What steps should I take, if the bleeding or the clutch hydraulic system, does not work?
