This warning could mean overheating, low fluid pressure, o r internal gearbox faults.

Faulty speed sensors, gear position sensors, o r solenoids can also trigger the warning.

Solution: Get an OBD-II diagnostic scan done immediately to read the fault codes. Avoid driving the car hard until the issue is fixed to prevent major damage.
