Have Transmission Questions? Ask a Mechanic for Answers ASAP
Hello and thank you for your question,The vehicle will go into third gear fail safe after codes P0885 sets.This code can be set due to any of the following with the PCM being the most common.
After replacing the transmission on a Hyundai two things will need to be done with a dealer scan tool (GDS). The codes will need to be cleared first. Secondly a transmission adaptive value reset will need to be performed to let the PCM know that the new transmission does not have an issue. If this is not done, the new transmission can act exactly like the one that had the issue, even if there isn't an issue with the new transmission. This is something only the dealer can perform.
