Dexron 3 is a successor to Dexron II and offers improved anti-wear and anti-shudder properties, as well as better resistance to oxidation and thermal breakdown.
Dexron 3 is characterized by its higher viscosity index, which means it is more resistant to changes in viscosity at different temperatures.
It also has a lower friction coefficient than its predecessor, which helps to reduce wear and tear on transmission components.
Dexron 3 is suitable for use in a wide range of vehicles, including passenger cars, trucks, and buses, and it can be used in both automatic and manual transmissions.
However, it is important to note that Dexron 3 may not be compatible with newer transmissions that require more advanced fluids, such as Dexron 6 or Dexron 7.
Overall, Dexron 3 is a reliable and effective ATF that offers good performance for older vehicles. If you are unsure whether Dexron 3 is right for your vehicle, be sure to check your owner’s manual or speak to a professional mechanic.
Details on Dexron 4
Dexron 4 is a type of automatic transmission fluid (ATF) that was introduced by General Motors (GM) in 2005.
It is a synthetic blend fluid that is designed to meet the performance requirements of automatic transmissions used in newer vehicles, particularly those manufactured after 2006. Dexron 4 is a successor to Dexron 3 and offers improved performance, durability, and protection for modern automatic transmissions.
Dexron 4 is characterized by its lower viscosity index, which means it provides better fluidity and smoother shifting, even in cold temperatures.
It also has a higher friction coefficient than its predecessor, which helps to improve transmission efficiency and fuel economy.
Additionally, Dexron 4 has excellent oxidation resistance, which means it is less likely to break down and degrade over time, resulting in longer fluid life.
Dexron 4 is compatible with a wide range of vehicles, including passenger cars, trucks, and buses, and it is recommended for use in newer transmissions that require more advanced fluids.
However, it is important to note that Dexron 4 should not be used in older transmissions that were designed for Dexron 3 or earlier, as it may not provide the same level of protection and performance.
Overall, Dexron 4 is a high-quality and reliable ATF that offers excellent performance and protection for modern automatic transmissions. If you are unsure whether Dexron 4 is right for your vehicle, be sure to check your owner’s manual or speak to a professional mechanic.

Explanation of the Table
The table comparing the specifications of Dexron 3 and Dexron 4 provides a helpful overview of the key differences between these two types of automatic transmission fluids.
However, to better understand these differences, it’s important to take a closer look at each of the individual specifications and what they mean for the performance of your transmission system.
Base Oil
The base oil used in an automatic transmission fluid can have a significant impact on its overall performance.
Dexron 3 is a mineral-based fluid, which means it is derived from crude oil.
This type of base oil is less expensive and more readily available than synthetic fluids, making it a popular choice for older vehicles. However, mineral-based fluids are also more susceptible to breakdown and degradation, which can reduce their effectiveness over time.
Dexron 4, on the other hand, is a synthetic blend fluid, which means it is a combination of synthetic and mineral-based oils. This type of fluid is designed to offer the benefits of synthetic fluids, such as improved performance and longevity, while still being more affordable than fully synthetic fluids.
Synthetic blends are also less likely to break down and degrade over time, which can help to prolong the life of your transmission system.
Viscosity
Viscosity is a measure of how thick or thin a fluid is. Automatic transmission fluids need to have a certain level of viscosity to properly lubricate and protect the moving parts within the transmission system.
Dexron 3 has a higher viscosity index than Dexron 4, which means it is thicker and more viscous. This can be beneficial in older transmissions that require thicker fluids to properly lubricate and protect their moving parts.
However, in newer transmissions that are designed to operate with thinner fluids, using a thicker fluid like Dexron 3 can result in reduced efficiency and performance.
Dexron 4, on the other hand, has a lower viscosity index than Dexron 3, which means it is thinner and more fluid. This can be beneficial in newer transmissions that require thinner fluids to achieve optimal performance and efficiency.
But, in older transmissions that are designed to operate with thicker fluids, using a thinner fluid like Dexron 4 can result in increased wear and tear on the moving parts within the transmission system.
Friction Coefficient
The friction coefficient of an automatic transmission fluid refers to how much resistance it provides against the moving parts within the transmission system.
A higher friction coefficient can be beneficial in certain situations, such as when you need to improve efficiency and fuel economy. However, it can also result in increased heat generation and wear and tear on the transmission system.
Dexron 4 has a higher friction coefficient than Dexron 3, which means it can provide better efficiency and fuel economy.
However, this may also result in increased heat generation and wear and tear on the transmission system, which can reduce its overall lifespan.
And Dexron 3 has a lower friction coefficient, which means it provides less resistance against the moving parts within the transmission system seminararbeit schreiben lassen. While this can result in reduced efficiency and fuel economy, it can also help to prolong the life of your transmission system.
Fluid Life
The fluid life of an automatic transmission fluid refers to how long it can effectively lubricate and protect the facharbeit schreiben lassen moving parts within the transmission system before it needs to be changed.
Using a fluid beyond its recommended lifespan can result in reduced performance and increased wear and tear on the transmission system.
Dexron 4 has a longer fluid life than Dexron 3, which means it needs to be changed less frequently. This can help to save you money on maintenance costs in the long run.
Friction Durability
Dexron 4 is a better lubricant than Dexron 3, which means it reduces friction and wear between the transmission components bachelorarbeit schreiben lassen kosten. It has been designed to withstand higher operating temperatures and is more resistant to oxidation and thermal breakdown.
In contrast, Dexron 3 has a lower friction durability, which means it may not provide the same level of protection under extreme operating conditions.
Seal Compatibility
Another crucial factor to consider is the compatibility of the ATF with the transmission’s seals.
Dexron 4 is formulated with more advanced seal materials, which means it is less likely to cause seal deterioration or leaks. In contrast ghostwriter hausarbeit, Dexron 3 may cause seal shrinkage and hardening over time, which could lead to leaks and loss of ATF.
Fuel Efficiency
Dexron 4 is a more fuel-efficient ATF than Dexron 3, mainly because of its lower viscosity and better friction durability.
It reduces the power loss associated with fluid friction, leading to improved fuel economy aufsatz schreiben lassen. This is an essential factor, especially for vehicles that are driven frequently or for long distances.
