A university transcript contains a list of the course units taken, the exams you have passed, and the credits gained.  In the Transcript of Records – TOR, you can usually see:
The course unit code (basically the code the host university gives to a specific academic course)
The title of the courses you have attended at your host university
The duration of the course (if one semester or two)
The local grade (your exam mark, which is very important to get your ECTS credits)
The ECTS credits you have gained by passing the exam
