If its out of warranty maybe take it to an independent transmission specialist for some diagnostics.

A bit late replying, but:

I had the DCT fail in my 2015 GD CRDi, with a bit over 300,000kms late last year. Lost all odd numbered gears.

With the dual clutches, one does the odd numbers and the other does even numbers and reverse.

Mine cost a bit over $5,000 to fix (trade price). That was for actuators and clutches, and a new flywheel.

I had mine done at a dealer.  None of the specialist transmission places I went to would touch it, they said that they didn't have the gear and you need Hyundai proprietary software to reprogam the DCT after repairing it.
