2004 Hyundai Tiburon Q&A
2004 Hyundai Tiburon Question: Transmission module indicator is causing check engine light to go on and stay on?
This computer controlled system needs to be scanned to see what code has been set. When you know that code, then you can address why the transmission does not shift when in the manual mode. - dandd
Your codes will all be 5 digits, starting with a P. Like, P0701 or P0763. Without those codes, it's hard to give any suggestion. It's also impossible to diagnose the vehicle first hand. Your information is incomplete, unfortunately, so it's hard to really make any suggestion about your Tiburon. I'm not familiar with a part called a "transmission control indicator" That may be what you call the warning light. - DaveJHM
