My daughter was driving normally and heard a pop and lost speed. Motor revs but no power to wheels in drive. Moves very slow and grinding noise when put into park, but has no park, will still roll in park.

Hi Luke,

This sounds like the parking pawl inside the transmission broke or possibly an input gear. The fact that it doesn't hold in park makes me think it is the parking pawl but either way, this is definitely something inside the unit.

Unfortunately there is no easy fix if I am correct. You are going to need to remove the transmission and disassemble it to find out exactly what it is.

Sorry I don't have better news. Let me know if you have questions. Thanks

Thanks so much! Is there any way it could be a solenoid or fuse?

Unfortunately that is unlikely. The grinding noise is an indication that it was something mechanical. Sorry to not have better news.
