New 2023 HTC with only 534 miles had check engine light come on. Was told it needs complete transmission replacement but dealer says none available from GM. Anyone have ideas on where to go from here? Obviously GM knows about this based on TSB.
 
C8 Transmissions aren't something GM normally stocks, however, your dealer should open up a GM TechLine case. Once GM approves replacement, the new transmission should show up at the dealership within a week.
