The D3 is the transmission that allows you to engage the first gear on your car. It creates comfort, providing a great driving experience for users when they move in street areas with many vehicles participating in traffic.

With D3, your car will not appear sluggish when accelerating and lose breath during braking. In addition, the D3 gearbox also helps the driver move quickly through mountainous terrain or uphill because it can break the engine.

In some cases, when your D transmission has an error and the mechanical or internal system, it will prevent the transmission from automatically shifting gears. Then you can use D2 and D3 to drive cars. Because it will give you a smooth driving experience like a manual transmission car.

Alternatively, for vehicles without the D1 or D2 markings, you can rely on the (-) and (+) symbols on the gear handle. Functionally, both D1 and D2 are similar. In essence, the character (+_ is just for shifting, the (-) symbol is for moving down.

The D3 transmission helps your car accelerate smoothly at low speeds if you want to overtake other vehicles. At that time, D3 will help increase the power of the engine significantly.

In just a short time, your car will reach outstanding speed, contributing to accelerating overtaking other vehicles quickly. At the same time, using the D3 gearbox also helps the driver protect the components from corrosion, improving the engine’s service life.

Currently, many people find it challenging to distinguish between D3 and D4. In essence, the intended use of these two types of gearboxes is different.

Depending on the moving situation, you should use D3 or D4. Once you understand that, you are sure to have a great driving experience. In addition, whether you use any D3 or D4 gear position, you should check the transmission fluid color regularly. That way, you will ensure the safety of both parts.

Difference Between D4 And D3

Difference Between D4 And D3

Gear limit

Gear limit is the first difference when you mention D4 and D3. In which D3 keeps the gear limit of 1, 2, and 3. And D4 supports the gear limit of 1, 2, 3, and 4.

At the same time, D4 ​​will automatically choose the right gear for you during the movement. . Then, if you combine D1, D2, D3, and D4, your car will become significant as it can move in the range of 1 to 4.

Terrain factor

The terrain factor is the following difference between D3 and D4. D3 is suitable for terrain up and down slopes because the gear position of this gearbox is capable of taking on the role of braking and advancing suddenly. As for the D4, this gearbox is suitable for cars that frequently drive on flat highways.

However, cars with automatic transmission will be different from cars with manual transmission.

In particular, you will need to continuously control the lever for manual transmission cars from position 1 to position 4. As for the automatic transmission, selecting gears from the lowest to the highest and vice versa will be mechanical.

Therefore, you need to carefully consider whether to choose D3 or D4 for your driving process. With rugged mountainous terrain, using D3 will help you go through them effectively.

For urban areas or highways, the D4 will be the perfect choice for you. Don’t forget to check the transmission fluid regularly for the ultimate driving experience.

Some Frequently Asked Questions

Should I drive in D or D3?

For D3 and D, it is recommended to use a vehicle with a D3 gearbox. It will be ideal for you to move around the city than the D transmission.

Also, it would help if you used the D3 gearbox for traffic jams. Because it will help you have higher rpm and better response when driving at low speeds.

Besides, the most important thing is that you need to understand the acceleration of gears in all situations. Basically, between rack and pinion vs regular steering box, gears will help you have a better driving experience.

In addition, you need to pay attention to checking the car’s CVTF if you want the transmission to work efficiently.

What does D 1 2 3 on the car mean?

D1, 2, and 3 are different levels of numbers. In which, D1 is the slowest, followed by D2 and D3.

In addition, the gears of the D1 2 3 can also be used as brakes to slow down the vehicle when you stop at a red light or go downhill. In case your car’s brakes fail, you can ultimately use these gearboxes to brake, with D1 having the lowest speed.

Will the D3 help me ride faster?

The answer is NO. Driving with the D3 won’t make your car any faster. The D3 will operate with 1, 2, and 3 gears in automatic transmission vehicles, or sometimes it can lock in 3rd gear.

As a result, the D3 will help you drive efficiently at high speeds, low altitude, terrain up, downhill, and stop at red lights continuously.

Should I use the D3 on the highway?

You can use the D3 on the highway. However, that is not ideal. Because D3 is only suitable for places with low driving speed, uphill or downhill.

On average, the D3’s speed is 30 km/h or less. For highways, you should use D4 when the speed is more incredible than 40 km/h. The superior speed of D4 is 60km/h.

Conclusion

Hopefully, the article will help you better understand the D3 gearbox and how to distinguish D3 from D4. There will be 2 main differences between D3 and D4, which are geared limitations and terrain factors.

In addition, to drive effectively, you need to choose the proper transmission for the traveling conditions. For highways, the use of D4 is reasonable. As for crowded areas or terrain that goes up and down continuously, the D3 will be the perfect choice for you.
