Valve body included? Another possible thing is the computer has what they call shift adapts. It changes pressures to compensate for issues. They need cleared when the trans is repaired or altered. If you didn't have the battery disconnected for long that could cause some issues. OH another thing. The valve body bolt length. You have to be very careful because the size is close and they will hit the band and apply it. It can lock the drum still and make you slip the clutches to overcome it. I dunno. I would say put a pressure gauge on it and check the pressures in all ranges.
