Suggest to clear the 17125 DTC and see if it returns over time. It likely will. It means the seal inside the Torque Convertor is internally leaking tranmission fluid preventing the TC from fully locking up. It also means that the fluid will run a little hotter than normal and that fuel mileage will go down a little on the highway due to TC slipping. The fix for 17125 DTC is to replace the torque convertor.
