408 uses a Japanese Aisin transmission. The transmission types include a 5-speed manual transmission, 6AT transmission, and 6-speed dual-clutch transmission. The functions of the transmission are: 1. Changing the gear ratio to meet the traction needs under different driving conditions; 2. Enabling reverse driving; 3. Interrupting power transmission to the drive wheels when the engine starts, idles, shifts gears, or needs to stop for power output. Taking the 2020 Peugeot 408 Fun Edition as an example, its body dimensions are: length 4750mm, width 1820mm, height 1488mm, wheelbase 2730mm, fuel tank capacity 53 liters, and trunk capacity 455 liters.

As someone who frequently researches cars, I've learned that the 408 currently predominantly uses automatic transmissions, primarily the 6-speed or 8-speed Aisin models. The gear shifts are quite smooth when driving, with responsive performance, making it well-suited for daily driving to avoid the hassle of manual shifting. This automatic transmission uses computer-controlled shift points, delivering smooth downshifts when decelerating in city driving and seamless acceleration on highways without any jerking. It's recommended to regularly check the transmission fluid during use, typically replacing it every two years or 50,000 kilometers to prevent dirty oil from affecting performance. Some newer models even come with a sport mode, which makes gear shifts more aggressive when activated, ideal for mountain roads or stop-and-go traffic. The type of engine paired with the transmission is also crucial—the Peugeot 408 usually comes with a 1.6T turbocharged engine, ensuring balanced power output and improved fuel efficiency. To prolong the transmission's lifespan, avoid frequent hard acceleration and sudden braking in daily driving.

From a car repair perspective, the 408 mostly comes with an automatic transmission, available in 6-speed and 8-speed variants, commonly from the Aisin brand. I've encountered many owners bringing their cars in for maintenance, with common issues being transmission fluid leaks or sensor failures causing gearshift jerking. Maintenance is straightforward—just regularly check the fluid color and level. Each fluid change costs a few hundred yuan, and doing it on time prevents gear wear. The transmission's condition directly impacts driving safety, like smooth starts on slopes. Remember not to coast in neutral during daily driving, as it increases wear. The Peugeot 408's transmission matches well with the vehicle's structure and is quite reliable, more durable than some Japanese cars' CVTs, but professional tools are needed to adjust the driveshaft position during installation. If you notice unusual noises or sluggish responses during gear shifts, get it repaired promptly—small issues can escalate into expensive whole-unit replacements. I recommend owners pay attention to sound feedback and follow the manual for preventive maintenance.

I've been commuting with the 408 for almost a year now. It's equipped with an automatic transmission that delivers smooth and comfortable shifts during daily driving, without frequent gear changes that could cause dizziness in city traffic. The transmission is well-matched with the engine, providing natural handling during turns or acceleration, making it ideal for family use. Fuel consumption averages between 7-8 liters per 100 kilometers, and the automatic shifting not only saves effort but also reduces driving fatigue. The interior space is thoughtfully designed to complement the transmission layout, with conveniently placed control knobs on the driver's seat. The transmission adapts well to significant weather changes—for instance, it remains stable even after warming up in winter. The car performs reliably on occasional long trips, with the suspension system effectively reducing bumps for a smoother ride. Overall, it's a dependable and practical vehicle to drive.

Choosing the 408 mainly aims at saving money and fuel. The automatic transmission version has a slightly lower average fuel consumption than the manual one, saving a few hundred yuan in fuel costs for daily commuting each month. Maintenance expenses are also low, with an oil change costing around three hundred yuan, and the low failure rate reduces unexpected expenditures. In the long run, it offers good value for money, with the transmission and engine tightly matched for smooth operation, avoiding common issues found in other models. The resale value benefits from the reliable drivetrain. When selecting the transmission, comparisons with different brands revealed that Peugeot's parts are easy to find and cost-effective for repairs. Driving habits have a significant impact: avoiding sudden acceleration and maintaining stable RPMs helps save fuel and prolong component lifespan. The overall vehicle economy is notably well-matched.

The 408's transmission has undergone significant changes. The older models mostly featured a 5-speed manual, while the newer versions have been upgraded to 6-speed or 8-speed automatic transmissions, showcasing notable technological advancements. Compared to the manual shifting that required skill a decade ago, today's automatic transmissions are more intelligent, with sport modes enhancing driving pleasure. The brand's use of the Aisin series ensures reliability and stability, with minimal differences between low and high trim levels. When compared to other cars like Toyota or Volkswagen, the Peugeot 408's automatic transmission responds slightly faster but has slightly weaker noise control. Technological developments have made it more durable, and regular use of lubricants can extend its lifespan without issue. The entire automotive industry is moving toward automatic and efficient transmissions, and the Peugeot 408 keeps up with this trend by balancing safety and comfort. The driving experience improves year by year.
