Nissan Tiida uses a 5-speed manual and CVT transmission. The functions of the transmission are: 1. Change the transmission ratio; 2. Expand the torque and speed of the driving wheels; 3. Enable the car to drive in reverse; 4. Facilitate gear shifting or power output of the transmission. Taking the 2021 Nissan Tiida as an example, it is a compact car with body dimensions of: length 4393mm, width 1766mm, height 1539mm, wheelbase of 2700mm, and a body weight of 1180kg. The 2021 Nissan Tiida is equipped with a 1.6L inline 4-cylinder naturally aspirated engine, with a maximum horsepower of 184PS, maximum torque of 155Nm, maximum power of 90kW, and is paired with a 5-speed manual transmission.

The transmission of the Tiida depends on the specific model year. Around 2006, the first-generation domestically produced Tiida had different configurations: the 1.6L automatic version was equipped with a 4AT transmission, the manual version had a 5MT, and a sport version even used a 6MT manual transmission. After the 2011 facelift, the mainstream option became the CVT continuously variable transmission, especially for the 1.6L models, which mostly used CVT, known for its smoothness and fuel efficiency. The latest models still continue to use CVT, but it has been upgraded to include a simulated 7-speed function, improving fuel economy even further. If you're buying a used older Tiida, make sure to confirm the transmission type—the early 4AT consumes significantly more fuel than the current CVT. It's recommended to test-drive and experience the acceleration characteristics of the CVT, as its power response during startup differs from traditional AT transmissions.

I run an auto repair shop, and the Tiida typically comes with three types of transmissions: the early 4AT, the later CVT, and the manual transmission. The most frequently repaired is the older 4AT, which has a high rate of solenoid valve failures and noticeable gear shift jerks. The newer models now use Jatco CVT transmissions, but it's crucial to change the specialized CVT fluid regularly, otherwise the steel belt can easily slip. The most common issue we encounter is valve body damage caused by using the wrong oil, which can cost thousands to repair each time. I recommend a transmission service every 60,000 kilometers, especially for those who frequently drive in the city. The manual transmission is quite durable, but the clutch kit usually needs replacement by around 80,000 kilometers. When buying a car, pay special attention to the condition of the transmission fluid—if it's black and has a burnt smell, the damage is usually significant.

The current Tiida owner's manual states that it comes standard with a CVT continuously variable transmission, with steel belt transmission efficiency significantly higher than traditional AT. Its transmission control logic is quite intelligent—automatically increasing RPM to maintain torque when going uphill, and simulating downshifts to utilize engine braking when descending. However, there's a protection program during cold starts in winter; acceleration may feel sluggish until the engine warms up. To maximize fuel efficiency, drivers should learn to gently press the throttle, as sudden acceleration consumes more fuel. The manufacturer recommends changing the specialized NS-3 fluid every 80,000 kilometers, as using the wrong type may damage the steel belt.
