Changed OS now 4L80 won't shift

Been using 4L80e for years without a problem. I changed to a Flex Fuel 2bar OS (12216125) and did the 4L80e segment swap for the OS but now the trans will not shift. When I put it in gear for the first time it will shift normally, then after coming to a complete stop it will not go to first and seems to be stuck in second. When I command any gear with the scanner they all engage while moving. I don't have a log of the problem but any suggestion of what's going on is appreciated.

Fixed. Bad segment swap file.
