    if it was a torque converter, it would not move period.

    yes, you must prefill the converter.

    it sounds like the planeterys have failed in the forward drum. it is internal.

    I see you were over on my other web site 2 car pros.

    be carefull, the guy that answered you is not correct. you must prefill the converter but it did not cause your issue.
    not the valve body, it never makes noise.
    he is right to take it back as it is a warranty issue. make sure they flush the cooler to get all the junk out.

    if it was grinding, then that means metal is in the system. no, i would not use that converter as it is cantaminated with metal.
