Whether a transmission needs replacement can be determined by various fault signs. If the vehicle exhibits the following phenomena, high vigilance is required: when starting or accelerating, the engine speed increases but the vehicle speed rises slowly, which may be caused by insufficient lubrication due to transmission fluid leakage; obvious jolts or abnormal noises during gear shifting are usually caused by deteriorated fluid or blocked valve bodies; stuck gear levers that cannot shift gears may involve signal faults and require immediate inspection and repair; abnormal noises at idle or during driving indicate wear of internal parts; engine stalling when shifting from P gear to D gear may be related to too low idle speed or damaged lock-up solenoid valves. Daily maintenance requires regular checks of fluid level and quality, replacement of transmission fluid every 40,000 to 60,000 kilometres, and timely cleaning of valve bodies and filters. If the above symptoms are found, It is best to go to a professional maintenance point for diagnosis as soon as possible to avoid small problems evolving into costly transmission assembly replacement (costs range from approximately RM5000 to RM15000). At the same time, attention should be paid to avoiding sudden acceleration and frequent heavy-load driving to extend the transmission's service life.
