Transmission performance low意思

"Transmission performance low" is a warning or diagnostic message that indicates a problem with the transmission system of a vehicle. It means that the vehicle's computer has detected an issue with the way the transmission is functioning, and that the performance of the transmission is not up to the expected standards.

This message can be caused by a variety of issues, including problems with the transmission fluid, worn or damaged transmission components, electrical issues with the transmission control module, or problems with the sensors that monitor the transmission's operation.

If you receive a "Transmission performance low" message, it is important to have your vehicle checked by a qualified mechanic as soon as possible. Ignoring this message can lead to further damage to the transmission, and may result in a more expensive repair bill.
