Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###

### Question ###
What is the lap total for the grid under 15 that retired due to transmission?

### Accurate SQL ###

SELECT SUM(laps) FROM table_name_65 WHERE grid < 15 AND time_retired = "transmission"
