alright, first thing, when im in third gear at about 3k rpm there seems to be some vibration that i can feel in my right foot ( through the floor ) and it gets more apparent the higher the rpm go. second thing is i was driving my car tonight i shifted from first to second at about 3500, i shifted kinda hard, but i punched it in second and it popped out of gear. what would cause this? is my tranny/clutch still ok??
