What is the difference between DSS transmission and AT transmission?
2 Answers
Introduction to the differences between DSS transmission and AT transmission: 1. Different meanings: DSS transmission is a dual-clutch transmission, while AT transmission generally refers to an automatic transmission. 2. Different compositions: Manual transmissions mainly consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions (AT) are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic transmission and gear combinations. Maintenance methods for automatic transmissions: 1. Power transmission requires adding transmission oil as specified: Do not opt for cheaper or more convenient manual transmission oil, as this can cause severe burning of clutches and brakes. 2. In addition to adding the specified oil: It is also necessary to use the correct type of transmission oil, otherwise issues like clutch slippage and hot gear jumping may occur. 3. The addition of automatic transmission fluid (ATF) must be strictly controlled: The ATF level must be between the bottom of the planetary gears and the top of the control valve body. If the fluid level is too high, the planetary gears' agitation can cause the ATF to foam, leading to oil leakage during driving. If the fluid level is too low, clutches and brakes are prone to slippage.
I've driven cars with various types of transmissions. The AT (Automatic Transmission) is the traditional automatic one, with very smooth gear shifts, especially in traffic jams or at low speeds, where you can hardly feel any jerking—it's very comfortable. In comparison, the DSS (Dual-Clutch Sport Shift) transmission is actually a dual-clutch type, offering lightning-fast gear changes and direct acceleration response, giving a strong sense of sportiness. However, in urban traffic congestion, the DSS might exhibit slight hesitation, making it less friendly. For someone like me who commutes daily, I prefer the smoothness of the AT. Additionally, the DSS is more fuel-efficient and performs well during high-speed cruising, while the AT, though slightly less fuel-efficient, has a simpler structure, costs less to maintain, and is more durable. My recommendation is to choose based on driving conditions: opt for the AT for city driving, and consider the DSS if you're after driving excitement.
