The X7 is equipped with an 8AT transmission. Below is relevant knowledge about automotive transmissions: Function of transmission: To alter the gear ratio between the engine and wheels, enabling the engine to operate under optimal conditions while expanding the torque and rotational speed transmitted to the drive wheels, thereby achieving varying speeds. It allows the vehicle to reverse and includes a neutral setting. Working principle of transmission: When the vehicle is in gear-shifting mode, the driver disengages the input shaft clutch, causing the transmission input shaft to lose power. The wheels then become the driving component, transmitting power back to the transmission. The output shaft sliding gear engages with the second driving gear on the input shaft via a shift fork, completing smooth gear shifting.

I've driven the X7 and felt its transmission is the Shengrui 8AT automatic gearbox. This transmission is quite common among domestic cars. The gear shifts are relatively smooth, but occasionally there's a bit of jerkiness, especially in traffic where the automatic shifting isn't very responsive. For daily use, its fuel efficiency is average, with city driving consuming about 9L per 100km, and it's more economical on highways. Maintenance costs aren't high—just a transmission oil change every 30,000 km on average. However, if you buy a used one, you should be cautious about the transmission's durability, as I've seen owners report slower response after a few years of use. Overall, this transmission is quite suitable for city commuting—it's easy to drive—but if you're looking for a sporty feel, it falls a bit short.

As a seasoned driver, I know the X7 uses a Shengrui 8AT transmission. This type of transmission is quite common among domestic SUVs. In terms of performance, it offers quick initial response but lacks intelligent shift logic. While it provides smooth acceleration at high speeds, the response can be a bit sluggish when overtaking. From a maintenance perspective, this transmission is relatively low-cost, with filter or fluid changes costing just a few hundred yuan. Regarding reliability, domestic transmissions tend to have fewer minor issues initially, but after prolonged use of 5 years or more, problems like unusual noises or oil leaks may arise. My advice is that regular maintenance can extend its lifespan. Compared to joint-venture brands, its biggest advantage is high cost-effectiveness, though the driving feel isn't as refined as imported vehicles.

Having worked in an auto repair shop for many years, I've handled quite a few X7 cases. The transmission is a Shengrui 8AT, and most owners complain about slight shaking during startup or delayed gear shifting. Common issues include transmission oil pump failure or rapid gear wear – once it exceeds 100,000 kilometers, regular inspections become necessary. Repair costs aren't expensive, with parts replacement typically costing a few thousand yuan, but neglecting maintenance could lead to bigger problems. For this vehicle, regular oil changes are essential, once a year is sufficient. Additionally, it's more suitable for city driving as the transmission noise becomes noticeable during long-distance trips. Overall durability is decent, slightly more worry-free than manual transmissions, but used car buyers should thoroughly test the gear-shifting functionality.

When I was browsing for used cars, I checked out the X7, which uses a Shengrui 8AT automatic transmission. This transmission offers smooth starts, but noticeable jerking when accelerating, which affects the driving experience. Maintenance is convenient, as even a roadside shop can handle the servicing. In terms of reliability, it has few faults during the initial years, running quietly and fuel-efficiently, but after a few years, it might throw fault codes, such as gear hesitation warnings. If buying used, it's advisable to check the maintenance records and test-drive it first—cars with well-functioning transmissions hold higher value. The car is comfortable for city driving, with good wind noise control on highways, though the transmission response is a bit slower; overall, it's not recommended for aggressive driving. Replacing the transmission costs around 10,000 yuan, so don’t just focus on the exterior when choosing a car.

As a car enthusiast, I've researched domestic SUVs, and the X7 is equipped with a Shengrui 8AT transmission. This domestic transmission technology is relatively mature, offering linear acceleration and moderate shift logic, providing good comfort during driving but lacking excitement. To expand, it performs stably during the new car phase, but after two years, there's a slight increase in fuel consumption, so attention to maintenance intervals is needed. In the industry, domestic transmissions are improving rapidly, with similar models performing well in Haval or Changan vehicles. The cost of ownership is low, with transmission oil needing replacement just once a year. It performs best in urban driving, but there's noticeable lag during high-speed overtaking. Long-term reliability is decent, but prolonged high-load conditions should be avoided. When choosing a car, comparing with joint-venture brands shows clear advantages in price.
