Can You Continue Driving When the Transmission Warning Light Is On?
1 Answers
You should not continue driving when the transmission warning light is on. The illumination of the transmission warning light indicates a fault in the powertrain control system, which could be due to a wiring issue with one of the transmission sensors. The specific fault can be diagnosed using a computer scan tool to read the fault code. The solutions for a transmission warning light are as follows: 1. Occasional or persistent faults in the automatic transmission's electronic components (sensors, solenoids, or the control module): The transmission warning light (some models do not have a dedicated transmission warning light, and transmission faults may trigger the engine warning light instead) will illuminate; replacing the faulty electronic components can resolve the issue. 2. Mechanical faults in automatic transmission vehicles: Severe transmission issues such as engine revving without acceleration, transmission slipping, clutch burnout, or failure to move after pressing the accelerator may trigger the transmission control unit to activate a fault alert, causing the transmission warning light to illuminate; these issues require inspection and repair at a service center. 3. Transmission fluid overheating causing the warning light to illuminate: This can occur due to overfilling of transmission fluid or blockages in the transmission cooler (internal or external, often during hot weather), as well as torque converter slippage leading to transmission overheating protection. Changing the transmission fluid can resolve this issue.
