when the pump was sent to the builder so were the drums, and valve body. The builder then repacked the drums with all new clutches and steels then went thru the valve body, a new pump was ordered at the same time from the same shop. he then sent to me and I reinstalled into a freshly washed and blown dry case. I would guess its a ring in there some where. if not it will all go to a trans shop and I will spend another few hundred on a rebuild for a rebuild?? see why its frustrating to me. I will win the battle i promise you that.
