I notice it the other night when driving home. As soon as I got it home I haven't driven it since. It shifts fine while sitting with the car off, but when driving or sitting with the motor running, it won't go into gear or come out of gear. I noticed a little fluid around the shaft on the master cylinder on the inside of the car. I changed the master and slave cylinder, and bled it until there were no more air bubbles coming out from the line, but it's still not shifting. I'm going to try and re-bleed it tom and completely flush the line and hope for the best. Anyone have any ideas of anything else that could be causing this?
