When stopped at a red light, do you need to switch to N or to D? The Secret to Making Your Gearbox Last Longer!

1. The role of the habit of changing gears when stopping at red lights

When stopping at a red light, many people think that shifting to neutral (N) will help reduce the load on the transmission. However, there are cases where drivers keep the car in D gear to avoid losing power when shifting gears. This choice depends on the design of the gearbox as well as the type of lubricant being used.

Switch to number N:
The main benefit is reduced pressure on the powertrain when the vehicle is stopped. This helps reduce friction between gears and reduces the operating temperature of the transmission.

However, continuously shifting to N can cause loss of control of the powertrain when a quick restart is required.

Keep the car in D:
When keeping the car in D gear, the transmission continues to operate, but with a lower load. This helps the system always be ready to restart without wasting time shifting gears, but it also means that the pressure on the transmission is not completely reduced.

So, which option is best? Experts say that, if properly maintained and using standard lubricants, the transmission can withstand the pressure when the vehicle is in D gear without causing serious wear and tear. In this case, the most important factor is lubricant quality.

2. The importance of standard lubricants

Correct lubricants create an optimal protective film between components in the gearbox. Not only does it help reduce friction, but it also keeps the system operating at the ideal temperature. If poor quality lubricants are used, gearbox parts will quickly wear out, leading to reduced performance and increased repair costs.

To ensure the best performance for the gearbox, periodic oil changes (usually every 40,000 - 60,000 km) are necessary. Gartz lubricant products, with advanced production technology from Germany and imported from Singapore, are designed to protect the transmission optimally, helping to minimize wear and increase the life of the transmission system.

3. Introducing Gartz's 9G-HP product
