Possible reasons for the automatic transmission emergency lamp to light up:
Mechanical problems:
*Low transmission fluid level
* Transmission fluid leaks
*Damaged or worn transmission parts
* Problems with the oil pump
*Differential problems
Electrical problems:
* Faulty transmission speed sensor
* Faulty shift solenoid
* Problems with wiring or connectors
*Transmission control module (TCM) malfunction
Other problems:
* Transmission temperature is too high or too low
*Transmission slipping
*Unusual transmission noise or vibration
Actions when the automatic transmission emergency lamp lights up:
*Stop Safely: Pull to the side of the road and park in a safe place.
* Check the transmission fluid level: Using the dipstick, check the fluid level and condition. It must be clean and at the appropriate level.
* Check for Leaks: Inspect the transmission and the area around it for fluid leaks.
* Scan for trouble codes: Use an OBD-II scanner to read any diagnostic trouble codes that may indicate an underlying problem.
* Restart the engine: After checking the fluid level and inspecting for leaks, restart the engine. If the lamp goes out, it may be a temporary failure.
*Consult a mechanic: If the light remains on or if you notice leaks or other problems, contact a qualified mechanic for further diagnosis and repair.
Precautions:
* Avoid driving with the automatic transmission emergency light on. This may cause further damage to the transmission.
*If you need to drive for a short distance with the light on, shift to the highest gear to reduce the load on the transmission.
* Maintain your transmission regularly, including changing the transmission fluid and filter according to the manufacturer’s recommendations.
