What is a 6-speed automatic transmission (AT)? Structure – Principle – Advantages and disadvantages

In this article, Gartz will help you understand more about6-speed automatic transmission, from structure, operating principle to advantages and disadvantages of this type of gearbox.

1. What is 6-speed AT automatic transmission?

6-speed AT automatic transmission is an automatic transmission system that can change gears automatically without driver intervention.

This system helps the vehicle operate smoothly and save fuel. With6 gears, 6-speed AT gearbox is widely used on cars from popular to high-end, providing a smooth and efficient driving experience.

2. Structure of 6-speed AT gearbox

The 6-speed AT gearbox includes the following main parts:

• Torque Converter: Is the part that helps transmit power from the engine to the gearbox, helping the car start smoothly without jerking.

• Planetary Gear Set: Determines the transmission's ability to change gears, allowing the vehicle to move smoothly and efficiently.

• Hydraulic control valve and electronic control unit (TCM): Coordinates the operation of the gearbox system, helping the vehicle shift gears accurately and smoothly.
   

• Transmission oil cooling system and sensor: Helps maintain ideal temperature, protecting the system from overheating.
   

3. Operating principle of 6-speed AT gearbox

The 6-speed AT gearbox operates based on the coordination mechanism between the hydraulic torque converter, planetary gear set and clutches. When the vehicle starts moving, the system automatically adjusts the gears to maintain engine performance and fuel economy.

• Low gear (1st, 2nd): Provides large torque, suitable when the vehicle starts moving or when climbing a slope.
   

• High-order progression (Numbers 5, 6): Helps save fuel when running at high speeds or on highways.
   

4. Advantages of 6-speed AT gearbox

• Smooth shifting: Shifting between gears is almost seamless, giving the driver a smooth experience.
   

• Fuel economy: Reasonable transmission ratio helps the engine maintain stable performance, minimizing fuel consumption.
   

• Increase engine life: 6-speed AT gearbox helps keep engine rpm low, limiting engine overheating and wear.
   

5. Disadvantages of 6-speed AT gearbox

• High maintenance costs: Due to its complex structure, the 6-speed AT gearbox requires high repair techniques and specialized equipment.
   

• Cost of replacement parts: Replacing specific components for 6-speed AT gearboxes is often more expensive than other gearboxes.
