What is the best 4-speed automatic transmission?

In the Malaysian market, 4-speed automatic transmissions (4AT) have gradually been replaced by more advanced 6AT, 8AT, and CVT transmissions, but some classic models still utilize this mature technology. Taking Toyota as an example, its 4AT transmissions are renowned for durability and low maintenance costs, having been extensively installed in older models like the Vios and Hilux, making them suitable for cost-conscious consumers. For those seeking 4AT-equipped models, considering pre-owned Toyota or Honda vehicles in the secondary market is advisable due to their affordable maintenance and ample spare parts availability. For contemporary mainstream new vehicles, opting for 6AT or higher-tier transmissions is strongly recommended to achieve enhanced driving performance.
