Can Ross see course grades for transferred summer courses?

I took a summer math course at a community college and it showed up as a T on my transcript. I heard Ross admissions has access to the actual letter grade behind Pass/Fail courses, and I was wondering if they would also have access to the letter grade I earned for my transferred course?

Any authorized university official can obtain access to that information. The registrar maintains a copy of the transcript sent from the school which you sought transfer credit from.
