Among automatic transmission types, AT transmissions typically have the highest maintenance costs, followed by CVT, with DCT being relatively lower. Due to their complex structure, which includes precision components such as planetary gear sets and torque converters, AT transmissions require high technical expertise for repairs and incur expensive costs. For instance, repairing or replacing a faulty torque converter can cost anywhere from several thousand to over ten thousand ringgit, with maintenance expenses for high-end models being even higher. If the core steel belt of a CVT transmission wears out, the replacement cost ranges approximately from 10,000 to 40,000 ringgit. For DCT transmissions, replacing a dry dual-clutch costs around 4,000 to 5,000 ringgit, while a wet dual-clutch replacement ranges between 5,000 and 10,000 ringgit, resulting in overall maintenance costs that are lower than those of AT and CVT transmissions. Regarding maintenance intervals, It is best to change the transmission fluid for AT and CVT transmissions every 60,000 to 80,000 kilometres. Although some CVT models are marketed as "maintenance-free for life," industry experts still advise inspections at 120,000 kilometres to prevent potential failures. Maintenance costs vary significantly across different brands and models. For example, replacing the CVT assembly in a Sylphy costs about 20,000 ringgit, whereas the same procedure for a Civic or Corolla may reach up to 40,000 ringgit. Consumers should select the most suitable transmission type based on their specific vehicle usage needs and budget constraints.
