What does a check engine light tell you?
What does a check engine light tell you? Have the vehicle checked for trouble codes to isolate the problem. A check engine light is not dedicated to the engine only. A check engine light can also tell you that you have problems with the transmission including overheating, solenoid problems, speed sensors, slipping transmission and many other problems. What does it mean when a transmission light comes on? This means that your transmission fluid is hotter than normal causing your transmission to operate at a higher temperature. Should this light engage, check your transmission fluid level and engine coolant level immediately....
