What causes my Hyundai Elantra to get stuck in one gear o r go into “limp mode”?

When the transmission goes into limp mode stuck in a single gear, often second o r third, it’s a protective response triggered by the TCM o r ECU to prevent further damage. This is commonly caused by sensor failures like the input/output speed sensors, solenoid issues, o r internal transmission faults. A diagnostic scan will usually reveal transmission-related error codes e.g., P0700, P0715, P0720. Prompt diagnosis is critical to avoid major repairs.
