Anytime you swap out a complete motor, you're chances of having electrical glitches like this are incredibly high. This is mostly due to the ECU not being reprogrammed or not communicating correctly with other electrical sensors and components on the vehicle. To solve this issue, you'll have to have a professional mechanic complete a check engine light inspection so they can download all codes and determine if the ECU needs to be reprogrammed.
