The 408 is equipped with a 5-speed manual transmission, 6-speed automatic transmission, and 6-speed dual-clutch transmission. The Peugeot 408 is a compact car. Taking the 2020 Dongfeng Peugeot 408 as an example, its body dimensions are: length 4750mm, width 1820mm, height 1488mm, wheelbase 2730mm, and curb weight 1325kg. The 2020 Dongfeng Peugeot 408 features a front MacPherson independent suspension and a rear torsion beam non-independent suspension. It is powered by a 1.2T turbocharged engine with a maximum horsepower of 136PS, maximum torque of 230Nm, and maximum power of 100kW, paired with a 6-speed dual-clutch transmission.

I've been driving the 408 for almost three years now, equipped with a 6-speed automatic transmission. It feels very smooth to drive, with hardly any noticeable gear shift jerks. During daily commutes in traffic jams, I don't need to worry about shifting gears at all—just step on the accelerator and go. This gearbox is made by Aisin, known for its reliability, and I've never encountered any major issues. Maintenance is straightforward, basically requiring a transmission fluid change every two years. Fuel consumption is quite reasonable, slightly higher than a manual transmission but much more comfortable. The overall driving experience of the Peugeot 408 is very stable, with the transmission well-matched to the 1.6T engine, providing quick acceleration response. It's advisable to avoid prolonged aggressive driving to prevent overheating issues. Overall, it's perfectly suited for city commuting.

From a technical perspective, the 408 primarily comes equipped with a 6-speed automatic transmission, while some models offer an optional 6-speed manual. The automatic version uses the Aisin AF40 series, featuring intelligent shift logic and smooth power delivery, making it well-suited for daily driving. Structurally, it employs a planetary gear set, which simplifies maintenance and offers greater durability compared to dual-clutch transmissions, with fewer issues related to shuddering. Fuel consumption is around 8L in urban areas, with even better efficiency on highways. With proper maintenance, including fluid checks every four years, the transmission can typically last the lifetime of the vehicle. Peugeot has done a solid job in this area, avoiding the overly smooth but somewhat soft feel of CVTs used in some other cars. The transmission's reliable performance makes it an excellent choice for those who prefer steady and composed driving.

I recently purchased a 408, opting for the automatic transmission version. The 6-speed gearbox makes driving effortless, completely eliminating the need for frantic gear changes. In stop-and-go city traffic, it handles everything automatically, with responsive and smooth acceleration when pressing the throttle. I test-drove the manual version, which offers a stronger sense of control, but it can be tiring in traffic jams. The transmission feels reliable, and the salesperson mentioned it comes as standard equipment. Fuel consumption is lower than expected, making daily use stress-free. Overall, I'm satisfied and would recommend it to owners looking for low-maintenance vehicles.

With years of experience in car repair, I've handled numerous 408 transmission issues. Most of them are equipped with 6-speed automatic transmissions, commonly the Aisin model, which has a robust internal structure and low failure rate. Occasionally, I encounter oil seal leaks or fluid degradation, which can be resolved with timely fluid replacement. For manual transmissions, I've seen gear wear, mostly due to driving habits. It's recommended to check the transmission fluid every 40,000 kilometers to prevent minor issues from escalating. The Peugeot 408's transmission is well-designed, making daily maintenance hassle-free.

In the driving performance of the 408, the gearbox is a key component. The 6-speed automatic transmission ensures linear and smooth acceleration, paired with a 1.6T engine for stable power output; the manual version offers more driving pleasure with precise gear shifts. The type of gearbox affects the experience—automatic provides comfort and ease, ideal for family use. Fuel consumption is slightly lower for the manual, but the automatic has clear advantages in peak traffic congestion. Maintenance-wise, regular oil changes can extend its lifespan. Overall, choosing a gearbox should consider lifestyle scenarios, such as opting for automatic for city commuting being a wiser choice.
