I'm pretty sure he was talking about the front pump. If you had no problems with it before, and saw no problems/wear on the pump during the rebuild, it should be fine. He did say that the pressure regulator valve may not be seating all the way, or the band was out of adjustment. As an afterthought, he added that the gaskets on the valve body might be reversed. Check the adjustment of the band and see if that helps any. If not, drop the pan and check the valve body.
