I have a few friends from Jammu University and according to them the process to get transcripts from the university is quite simple. 

• You will need to visit the administration block of Jammu University. 
• Get the form and fill out the details of the degree for which you want transcripts.
• Attach proof of passing the said degree from Jammu University. It needs to be duly attested by your departmental head.
• Submit the required fee.
• Give the details of the agency or the institute where you want to send your transcripts clearly and you are done. 

Your transcripts should be ready to dispatch within 15 days or so, depending on the pending work.
