I have had this problem for a long time. I tried bleeding and it did nothing. Let me guess, sometimes you cant get it into gear either? And it's completely random, as in it will be REALLLLY bad and then 2 minutes later be just fine? I also am thinking slave cylinder and since it's inside the tranny, its gonna be a HUGE job to replace. I have a powertrain warranty that covers "all internal components of the tranny" and i was told this is still not covered. It sucks, but yeah you and I are screwed.
