The cost of gearbox repair varies significantly depending on the type, fault level, and repair channel. Manual gearbox repair costs are low: basic items such as clutch plate replacement cost approximately 600-2000 Malaysian Ringgit, while the repair of synchronizers or gears can cost up to 5000 Malaysian Ringgit. Automatic gearboxes (AT/CVT/Dual-Clutch) are more complex: repair of electronic control unit faults costs around 3000 Malaysian Ringgit, clutch plate replacement ranges from 2000 to 6000 Malaysian Ringgit, general overhaul of the assembly is usually 3000-10000 Malaysian Ringgit, and CVT steel belt repair is about 5000-8000 Malaysian Ringgit. For luxury models, assembly replacement may cost 30,000-100,000 Malaysian Ringgit. The fault level directly affects the cost: minor issues like oil circuit cleaning only cost 500-800 Malaysian Ringgit; moderate faults such as valve body repair range from 3000 to 8000 Malaysian Ringgit; severe damage or assembly replacement requires more than 10,000 Malaysian Ringgit. For example, CVT repair for the Nissan Sylphy costs about 8000 Malaysian Ringgit at 4S stores but only 6000 Malaysian Ringgit at third-party workshops. Changing the gearbox oil every 40,000-60,000 kilometres in daily use can greatly reduce the risk of major overhauls. If gear shifting jolts or abnormal noises occur, timely inspection should be carried out to avoid minor problems worsening and doubling the cost.
