Transmission Warning Light Comes On and Then Disappears After Restart?
1 Answers
There are several reasons why the transmission warning light comes on and then disappears after restarting: Failure of transmission electronic components: Intermittent or persistent faults in the electronic components of an automatic transmission can cause the transmission warning light to illuminate intermittently or continuously as an alert. The transmission may enter a limp mode (where it does not shift gears, the engine runs at high RPM, and acceleration is sluggish). Mechanical failure in the transmission: Severe mechanical failures in an automatic transmission, such as engine idling, transmission slipping, clutch burnout, or failure to move despite acceleration, can trigger the transmission control unit to activate a fault alert, causing the transmission warning light to illuminate.
