As a rule, a manual gearbox is considered more reliable than an automatic transmission for the following reasons:
* Fewer Moving Parts: A manual transmission contains fewer moving parts and components than an automatic, reducing the risk of failure.
*Manual Control: The driver has more control over the transmission, allowing him to avoid overheating or improper shifting that could lead to breakdown.
*Easier and less expensive to repair: Manual transmissions are typically easier and less expensive to repair than automatic transmissions because they contain fewer complex components.
* Long service life: Manual transmissions, when properly maintained and used, can last more than 150,000 km, which is longer than the average service life of an automatic.
* Wear resistance: Mechanical transmissions are less susceptible to wear due to the absence of friction clutches and a torque converter, which are used in automatic transmissions.
However, reliability also depends on factors such as:
*Care and Maintenance: Regular maintenance and transmission fluid changes are critical to extending the life of both manual and automatic transmissions.
* Driving style: Aggressive driving and harsh gear changes can damage both manual and automatic transmissions.
* Quality of workmanship: The reliability of a gearbox also depends on the quality of its workmanship and the components used.
Modern machines are also becoming more reliable thanks to improved designs, materials and electronic control systems. However, a manual transmission is still a more reliable option for some drivers and usage conditions.
