Hi,
If it goes through the process and doesn't change to 100%, it is likely related to the gauge control module (see pic below). However, I don't see how replacing the engine would have affected it. Are there any other electrical issues?
If the GCM is causing the issue, you should be able to find a fault code by scanning the can-bus.
Here is a link explaining how that is done:

Let me know if you have already tried this. Note: Scanning the can-bus will retrieve codes regardless of the module storing them. In this case, the GCM. A traditional scan tool won't be able to find the codes.
Let me know.
