What is the difference between AMT and AT transmissions?
2 Answers
The differences between AMT and AT transmissions are as follows: 1. Structure: AT transmissions consist of components such as the valve body, oil pump, clutch, brake, one-way clutch, diaphragm spring, elastic retaining ring, steel plates, friction plates, large sun gear, small sun gear, planetary carrier, and ring gear. AMT transmissions are essentially manual transmissions with automatic clutch and gear-shifting control functions, and their structure is fundamentally the same as traditional parallel-shaft manual transmissions. 2. Function: AT transmissions provide smooth gear shifts with minimal or no impact, especially in low-speed stop-and-go conditions, offering outstanding comfort. AMT transmissions, on the other hand, have relatively larger shift impacts (though advancements in electronic control technology have made gear shifts and timing more precise, reducing the impact). They are simple in structure, highly reliable, and easy to maintain.
I think there's quite a difference between AMT and AT transmissions. AMT stands for Automated Manual Transmission, which is essentially a manual gearbox structure with an automatic control system to handle gear shifts—like a manual but without the hassle of pressing the clutch. This makes it cost-effective and fuel-efficient, ideal for buyers on a budget or seeking economy. The downside is the noticeable jerking during gear shifts, especially during acceleration or uphill driving. AT, or Automatic Transmission, uses planetary gear sets and a torque converter, delivering smooth and quiet shifts that feel like gliding, with higher comfort levels, though it's pricier and less fuel-efficient. From my experience, AMT is simpler to maintain due to fewer parts and suits city driving, while AT requires regular oil changes but is more reliable for long trips. If you're a beginner or drive daily, AT is more hassle-free; but if you want to save money, AMT is worth considering. When choosing a car, don’t forget to check feedback on specific models—some AMTs perform well after optimization.
