When I accelerate, if I push on the peddal to hard or quickly, my RPM's jump up to 3000, 4000 or 4500 and my car barley accelerates. So I let off the gas and gradually increase speed. It does this in every gear. Once this problem started I took it in and the mechanic said it was the clutch slipping. He put a brand new clutch in and replaced some seels that were leaking. I got my car back today and drove around the block, 30mph and it was fine. Then I took it up to 55mph and the problem started again. And now it does it at any speed. Again. Im loseing my mind, what could it be?
