The maintenance cost of a gearbox can indeed be relatively high, with the specific cost depending on the type of gearbox, the severity of the fault, and the repair channel. For automatic transmissions (such as CVT or dual-clutch), due to their complex structure, moderate repairs (like valve body cleaning or clutch module replacement) range from 5000-10000 yuan, while complete assembly replacement for luxury models can even reach 30,000-100,000 yuan. For instance, repairing a Sylphy CVT transmission costs about 8000 yuan at a 4S dealership, whereas third-party shops may charge only 6000 yuan. It is recommended that vehicle owners change transmission fluid regularly (every 40,000-60,000 kilometres) and promptly address issues like gear-shifting jerks or unusual noises to prevent minor problems from escalating and doubling repair costs. For economy vehicles, setting aside a repair budget of 5000-15,000 yuan is advisable, while luxury car owners should prepare at least 30,000 yuan.
