2018 Chevy Malibu Transmission Fluid Type Guide

Transmission Fluid Specifications for Your Chevy Malibu

When it comes to keeping your 2018 Chevy Malibu running smoothly, one of the most critical components to pay attention to is the transmission fluid. This fluid not only lubricates the moving parts of the transmission but also helps in cooling and cleaning. Using the correct type of transmission fluid is essential for optimal performance and longevity of your vehicle.

Manufacturer’s Recommendations

For the 2018 Chevy Malibu, General Motors specifies the use of Dexron VI transmission fluid. This fluid is designed to meet the stringent requirements of GM’s automatic transmissions, ensuring that your vehicle operates as intended.

Why Dexron VI?

Dexron VI is a synthetic fluid that provides several advantages over older formulations. Here’s why it’s the go-to choice for your Malibu:

• Improved Performance: Dexron VI offers better thermal stability, which means it can handle higher temperatures without breaking down. This is crucial for maintaining performance, especially during heavy driving conditions.


• Enhanced Lubrication: The synthetic base oil in Dexron VI provides superior lubrication, reducing wear and tear on transmission components. This can lead to a longer lifespan for your transmission.


• Better Fuel Efficiency: With improved friction properties, Dexron VI can help your transmission shift more smoothly, which can contribute to better fuel economy.


• Compatibility: Dexron VI is backward compatible with previous Dexron fluids, meaning you can use it in older models without issues. However, it’s always best to stick to the manufacturer’s recommendations.

Checking Fluid Quality

While you won’t be checking the fluid level with a dipstick, it’s still crucial to monitor the condition of your transmission fluid. Here are some signs that your fluid may need attention:

1. Color: Healthy transmission fluid is typically a bright red color. If you notice it turning brown or black, it may be time for a change.


2. Odor: If the fluid smells burnt, that’s a red flag. Burnt fluid can indicate overheating and potential damage to your transmission.


3. Texture: Transmission fluid should feel smooth. If you notice any grit or particles, it could be a sign of internal wear.

Where to Find Dexron VI

You can find Dexron VI at most auto parts stores, and it’s also available at dealerships. Always ensure that the fluid you purchase meets the Dexron VI specification to avoid any compatibility issues.

By sticking to the manufacturer’s recommendations and using the right type of transmission fluid, you can help ensure that your 2018 Chevy Malibu remains reliable and performs at its best for years to come.

Change Interval for Transmission Fluid

Maintaining your 2018 Chevy Malibu involves more than just regular oil changes. One of the critical aspects of vehicle maintenance is keeping an eye on your transmission fluid. The change interval for transmission fluid can vary based on driving conditions, but a general guideline is to change the fluid every 30,000 to 60,000 miles (approximately 48,000 to 96,000 kilometers ).

Manufacturer Recommendations

General Motors recommends checking the transmission fluid condition regularly, especially if you engage in severe driving conditions such as towing, frequent stop-and-go traffic, or driving in extreme temperatures. Here’s a breakdown of the recommended intervals:

• Normal Driving Conditions: 60,000 miles (96,000 km)


• Severe Driving Conditions: 30,000 miles (48,000 km)

Why Change Transmission Fluid?

Changing the transmission fluid is essential for several reasons:

• Prevent Overheating: Old fluid can lose its ability to lubricate and cool the transmission, leading to overheating and potential damage.


• Remove Contaminants: Over time, transmission fluid can accumulate dirt, metal shavings, and other contaminants that can harm the transmission.


• Maintain Performance: Fresh fluid helps ensure smooth shifting and optimal performance, making your driving experience more enjoyable.

Partial Transmission Oil Changes

In many cases, a complete transmission fluid change involves removing the transmission from the vehicle, which can be a labor-intensive and costly process. This is where partial transmission oil changes come into play.

What is a Partial Change?

A partial transmission fluid change involves draining a portion of the old fluid and replacing it with new fluid. This method can be beneficial for maintaining fluid quality without the need for a complete transmission service.

Why Consider Partial Changes?

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


• Less Labor Intensive: Since it doesn’t require removing the transmission, the process is quicker and simpler.


• Regular Maintenance: Performing partial changes more frequently can help keep the fluid cleaner and reduce the buildup of contaminants.

Statistical Data and Authoritative Sources

According to the Automatic Transmission Rebuilders Association (ATRA), regular maintenance, including fluid changes, can significantly extend the life of your transmission. They recommend that vehicle owners consider partial changes as a viable option to maintain fluid quality, especially in high-mileage vehicles.

Additionally, a study published by the Society of Automotive Engineers (SAE) found that vehicles that underwent regular fluid maintenance, including partial changes, experienced fewer transmission failures compared to those that did not. This highlights the importance of keeping your transmission fluid fresh, even if a full change is not feasible.

By understanding the importance of change intervals and the benefits of partial transmission oil changes, you can make informed decisions that will help keep your 2018 Chevy Malibu running smoothly for years to come.
