Transmission rebuilt and smooth as can be and no issues. They did put in a new torque converter in and some of the other small parts that many claim fix the issue. @landlord
, if they are going to do the same for you I would not worry to much as it seems to fix this issue that is common or at least reported for some and known. I don't think they will tear too much apart other than what is needed to give you the smooth shifted you expect. If you have a black label you definitely want to make sure you are happy with the feel. My experience was good on this particular matter so I say if they are willing to dig deep in and check or replace anything worn, it may be worth it for you.
