I recommend that you do not power flush the transmission any more unless it
has been done routinely every 3 or 4 years since the transmission is new,
otherwise, you will have the problems that you are experiencing. If the
automatic transmission fluid is very black, then the most you should do is
drain and re-fill.
AFAIK, there are no OEM remanufactured valve bodies, only remanufactured
transmissions.
I doubt if replacing just the valve body would eliminate the harsh and
erratic shifting because the stuff that was dislodged by the power flush
could be stuck anywhere inside the transmission. My guess is that a new
valve body would cost in the neighborhood of $1,800 so that is a pretty
expensive part to replace without guaranteed success.
I would not attempt replacing a valve body without a factory repair manual.
I suggest that you look at the procedure and then you will have an idea of
whether it is something you want to tackle.
