    so the seal was or wasnt changed?

    seal was changed & pump was overhauled...which helped in the lifting but still fills tranny to the top of fill pipe with hyd oil...is there any other way hyd oil can get into trans...it does not have an emergency steering pump on trans....could it be the control valve assy ?

    id be looking at that or possibly if the park brake. how fast will it fill it?
