What is wrong with my chrysler town and country 2003 on 2003 Chrysler Town & Country

It started with the speed odometer going crazy then it would jump when I was driving then the check engine light came on I got the codes it was the input and output speed sensor I replaced both sensors and now speed odometer doesn't work at all and now my van won't shift into second gear was told the computer has to be reprogrammed is this true or do I need a new transmission? Thanks for your time :)

scan codes and post, sounds like trans is going into limp mode. seek a free diag and est from aamco. where did you purchase the sensors?
