I found a valve body with the same casting number as mine.It was listed(for sale) as a PB body,but it was a core trans and the shifter PB or console was really unknown. I am going to get it and compare the two.My valve body is cracked right next to the casting number,hairline with a small hole too!This would be an internal leak for sure.It may be repairable as it is on the top of the body away from the machined surface.I will post a photo of the crack and follow up with the final resolution,be it replacement or repair.
