ATS Transmission Fluid Type: Change Intervals & More

Understanding Transmission Fluid Types

When it comes to keeping your vehicle running smoothly, the type of transmission fluid you use is critical. Transmission fluid serves multiple functions, including lubrication, cooling, and hydraulic pressure. Using the right fluid is not just a recommendation; it’s essential for the longevity and performance of your transmission.

Manufacturer Recommendations

Each vehicle manufacturer has specific requirements for transmission fluid, and it’s crucial to adhere to these guidelines. Using the wrong type can lead to poor performance and even damage. Here’s a breakdown of some common specifications you might encounter:

General Specifications

– Viscosity: Most manufacturers recommend a specific viscosity grade for their transmission fluids, often indicated by a number (e.g., 5W-30). This number tells you how the fluid behaves at different temperatures.

– Additives: Transmission fluids often contain various additives to enhance performance. These can include detergents, anti-wear agents, and friction modifiers. Always check if the fluid meets the specific additive requirements set by your manufacturer.

– Type: There are several types of transmission fluids, including:
– Automatic Transmission Fluid (ATF): This is the most common type, used in automatic transmissions. Different formulations exist (like Dexron and Mercon), so it’s essential to use the one specified by your manufacturer.
– Continuously Variable Transmission Fluid (CVT): This fluid is designed for vehicles with CVTs, which require a different formulation to handle the unique operation of the transmission.
– Dual-Clutch Transmission Fluid (DCT): If your car has a dual-clutch transmission, it will require a specific type of fluid designed to handle the rapid shifts and high temperatures.

Common Fluid Specifications

Here’s a quick reference for some common transmission fluid specifications:

| Manufacturer | Recommended Fluid Type | Viscosity | Additive Specifications |
|————–|————————|———–|————————-|
| Ford | Mercon LV | 5W-20 | Must meet Ford spec WSS-M2C924-A |
| GM | Dexron VI | 5W-30 | Must meet GM spec 6094M |
| Honda | Honda ATF-Z1 | 5W-20 | Must meet Honda spec HCF-2 |
| Toyota | Toyota ATF WS | 5W-30 | Must meet Toyota spec T-IV |

Why Specifications Matter

Using the correct transmission fluid type is not just about following the manufacturer’s recommendations; it’s about ensuring your vehicle operates efficiently. Here are some reasons why specifications matter:

• Performance: The right fluid ensures optimal performance, allowing for smooth shifting and effective power transfer.


• Longevity: Using the specified fluid can extend the life of your transmission, reducing the likelihood of costly repairs.


• Warranty: If your vehicle is still under warranty, using the wrong fluid can void your coverage. Always check your owner’s manual.

Where to Find Manufacturer Specifications

You can find the recommended transmission fluid type in several places:

1. Owner’s Manual: This is your first stop. The manual will provide detailed specifications for your vehicle.


2. Service Manuals: If you have access to a service manual, it will offer in-depth information about your vehicle’s transmission system.


3. Manufacturer Websites: Many manufacturers provide detailed specifications online, including fluid types and service intervals.

In summary, understanding the type of transmission fluid your vehicle requires is crucial for maintaining its performance and longevity. Always refer to your manufacturer’s recommendations and specifications to ensure you’re using the right fluid.

Change Interval for Transmission Fluid

Understanding when to change your transmission fluid is crucial for maintaining your vehicle’s performance and longevity. The change interval can vary significantly based on the type of transmission, driving conditions, and manufacturer recommendations.

Recommended Change Intervals

Most manufacturers provide guidelines for how often you should change your transmission fluid. Here are some general recommendations based on various vehicle types:

• Automatic Transmissions: Typically, the change interval ranges from 30,000 to 60,000 miles (48,000 to 96,000 km). Some manufacturers may suggest longer intervals, but many mechanics recommend changing it more frequently, especially if you drive in severe conditions.
• Manual Transmissions: Manual transmission fluid often needs to be changed every 30,000 to 50,000 miles (48,000 to 80,000 km). Again, this can depend on driving style and conditions.
• CVTs (Continuously Variable Transmissions): Change intervals for CVTs can vary widely, but many manufacturers recommend changing the fluid every 30,000 to 50,000 miles (48,000 to 80,000 km) to maintain optimal performance.

Factors Affecting Change Intervals

Several factors can influence how often you should change your transmission fluid:

1. Driving Conditions: Frequent stop-and-go driving, towing, or driving in extreme temperatures can accelerate fluid degradation. If you often drive under these conditions, consider changing your fluid more frequently.
2. Fluid Quality: The type of fluid used can also affect how long it lasts. High-quality synthetic fluids may offer better protection and longer intervals compared to conventional fluids.
3. Vehicle Age: Older vehicles may require more frequent changes as the transmission components wear down, leading to increased fluid contamination.

Partial Transmission Oil Changes

In many cases, a complete transmission fluid change is not feasible without removing the transmission from the vehicle. This is where partial oil changes come into play.

What is a Partial Transmission Oil Change?

A partial transmission oil change involves draining a portion of the old fluid and replacing it with new fluid. This method is often used when a full fluid exchange is impractical or too costly.

Benefits of Partial Changes

– Cost-Effective: Partial changes are generally less expensive than full fluid exchanges, making them a more budget-friendly option for many vehicle owners.

– Easier Process: Since a full fluid change often requires specialized equipment and can be labor-intensive, partial changes can be performed more easily and quickly.

– Regular Maintenance: Regular partial changes can help maintain fluid quality over time, ensuring that your transmission remains lubricated and protected.

Justification for Partial Changes

Statistical data and expert opinions support the practice of partial transmission fluid changes. According to the Automatic Transmission Rebuilders Association (ATRA), regular maintenance, including partial fluid changes, can significantly extend the life of your transmission.

Additionally, a study published in the Journal of Automotive Engineering found that maintaining fluid quality through regular changes—whether partial or full—can reduce wear on transmission components and improve overall performance.

Many mechanics recommend that vehicle owners consider partial changes as part of their regular maintenance routine, especially if a full change is not feasible. This approach helps ensure that the transmission fluid remains effective in providing lubrication and cooling, ultimately leading to a longer-lasting transmission.

In summary, understanding the change intervals for transmission fluid and the benefits of partial changes can help you maintain your vehicle’s performance and reliability. Regular maintenance is key to avoiding costly repairs down the line.
