Hi,
The replacement needs possible programming. The first thing you need to do is confirm that TPS 1 and 2 parameters agree. If they do and it still won't shift, chances are you will need to reprogram the ECM.
I have attached information below showing the procedures for replacement. Note that there is a section that asks you if diagnostic codes are present. Based on that, you will follow different procedures.
Let me know if this helps or if you have questions.
Take care,
Joe
