Common codes include P0700 (general transmission fault), P0715 (input speed sensor), P0720 (output speed sensor), P0730-P0736 (gear ratio errors), and P0750-P0770 (solenoid issues). A scan tool reveals the specific code.
If the light is steady and the vehicle drives normally, you can usually drive to a repair shop. If the light is flashing, this indicates a severe problem - pull over safely and have the vehicle towed.
