I have a 2018 Elantra Sport with the DCT and I have noticed a very rough shift when I am wide open and it shifts from 2nd to 3rd gear. It happens regardless if I am in regular mode or in sport mode. It only happens when I have the gas all the way down. The shifts are smooth if I am not on the gas all the way. Any ideas as to what this could be? I only have 12k miles on the car, so the transmission shouldn't be bad.
