What does it mean when the transmission warning light comes on?
1 Answers
When the transmission warning light illuminates, it indicates an internal fault within the transmission system. The specific issue can then be identified by checking the diagnostic trouble codes, followed by appropriate repairs. Common causes for the transmission warning light include: failure of the control module, malfunction of shift solenoids, worn friction plates inside the transmission, or gear wear within the transmission. Transmissions are categorized into two types: manual and automatic. Manual transmissions primarily consist of gears and shafts, achieving speed and torque variation through different gear combinations. Automatic transmissions, on the other hand, are composed of a torque converter, planetary gears, a hydraulic torque variation system, and a hydraulic control system, utilizing hydraulic power transmission and gear combinations to adjust speed and torque.
