The shifter doesn't shift out of park without the override button which i wouldn't have a problem with except the override has become finicky and difficult to get it out of park even with the override. I'm told it's a relay in the shifter not letting it shift out of park and I'm trying to find out where that is.

Welcome to 2CarPros.

The shift interlock control module is in the center console. See the attached pictures.
Picture 3 is a wiring schematic of the system. I'm adding it in case it's needed.

Here are a few links you may find helpful when working on it:
