Will a 2013 transmission work on my 2011 gensis coupe 3.8

Hi this is Dusty, I'm one of the auto experts on RepairPal's Car Genius team. The best course of action is to contact your local Hyundai dealer to confirm the part number of the transmission in your vehicle & the donor vehicle. They'll likely ask you for your VIN of each vehicle for accuracy. There may be newer part numbers which can indicate that the transmission has been improved in some manner while the transmission itself remains the same as the vehicle applications it is utilized in.
