What it means
The transmission control system has detected a problem. To protect itself it may hold a single gear (limp mode), shift harshly, or delay engagement.
Can I drive?
Gently and briefly, to get it somewhere for diagnosis — but transmission trouble rarely gets cheaper by waiting. If it is overheating (a thermometer symbol) or barely moving, do not keep driving.
Common causes
Low or degraded fluid, a solenoid or sensor fault, or an internal issue. Fluid condition is one of the first things worth checking.
Warning-light symbols and meanings vary by vehicle - always check your owner’s manual. This is general guidance based on what the light indicates, not a physical inspection, and a light on its own never names a failed part.
