Hi there. The only way to fix a rear main seal is to remove the transmission, pull out the old seal with a seal puller, and install a new one. It is an extensive procedure and needs to be performed in a shop and special tools will be required to do this. I would recommend may be adding some thicker oil if it is not a bad leak and that may stop it from leaking as bad. If you need further assistance, I recommend you have a mechanic, like one from YourMechanic, inspect the leak and advise you on the necessary steps to take.
