What causes the gear indicator light to flash while driving normally in the Lavida?
2 Answers
Lavida gear indicator light flashing while driving normally is caused by transmission failure. The reasons for transmission failure are as follows: Internal contamination of the transmission: When an automatic transmission malfunctions, in many cases it's not due to internal valve body damage, but rather the presence of stubborn dirt and impurities inside. Especially when contaminants accumulate in the valve body causing blockages, this prevents effective regulation of oil pressure, leading to issues like jerking, impact, and slippage. High temperature damaging the transmission: High temperatures can degrade the quality and frictional properties of automatic transmission fluid, increasing friction and wear. This leads to transmission noise while also causing sludge to form inside the transmission, resulting in jerking and impact. If temperatures exceed 120°C, rubber sealing materials begin to harden, eventually causing leaks and reduced hydraulic pressure. At even higher temperatures, the transmission starts slipping, which in turn causes temperatures to rise further.
Recently, I encountered a similar situation where the gear indicator light on my Lavida flickers occasionally, yet the car drives smoothly. As an experienced driver with years behind the wheel, I suspect this might be caused by minor internal issues, such as a faulty gear position sensor or loose wiring. Wiring tends to send erratic signals when dampened or aged. Additionally, a poorly connected transmission control unit can also trigger this behavior, even if driving remains unaffected—yet potential risks shouldn't be ignored. I recommend inspecting the fuse box and connectors as soon as possible; try gently wiggling the wires to check for looseness. Regular simple maintenance, like cleaning the engine bay and checking electronic systems, helps prevent such issues. Remember, while this flickering light may not hinder driving, prolonged neglect could lead to other failures. Safety first—it’s best to have a professional diagnose it at a workshop.
