John , I just purchased the car march 10 2020 , the seller told me that it had a small leak and he just keep adding oil , on he's drive way I didn't see signs of oil leaks , the car drives and shifted well and is in very good conditions with 46.560 original miles , trailer it from Jacksonville to my home in FT Lauderdale next day drove it about 2 -3 miles no problems , let the car running in idle to charge battery and notice the oil pouring from transmission , ask the seller he sad he never had that kind of leak , I did not added any thing to stop leaks don't know if he done in the past .
