For the vehicle transfer in the mortgage stage, the answer is no, because before your loan is paid off, the nature of the vehicle is mortgaged in the bank (the vehicle management office has a mortgage record), and you have no right to transfer. You only have the driving license and the motor vehicle registration certificate (commonly known as the big green copy) are also detained by the bank, but you must provide the big green copy to transfer the ownership. You must pay back the money first, get the big green book, and then go to the vehicle management office to settle the mortgage for the record before you are allowed to transfer the ownership.
