2017 Chevy Impala Transmission Fluid Type Guide

Understanding Transmission Fluid Specifications

When it comes to keeping your 2017 Chevy Impala 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 your transmission but also serves as a hydraulic fluid, enabling the transmission to shift gears effectively. Using the correct type of transmission fluid is essential for optimal performance and longevity of your vehicle.

Manufacturer’s Recommendations

For the 2017 Chevy Impala, General Motors specifies the use of Dexron VI transmission fluid. This fluid is designed to meet the rigorous demands of modern automatic transmissions, ensuring smooth operation and effective protection against wear and tear.

Why Dexron VI?

The choice of Dexron VI is not arbitrary. Here are some reasons why this specific fluid is recommended:

• Enhanced Performance: Dexron VI is engineered to provide superior performance in both high and low-temperature conditions. This means your transmission will operate efficiently, whether you’re driving in the heat of summer or the chill of winter.


• Improved Longevity: This fluid contains advanced additives that help reduce oxidation and thermal breakdown, extending the life of your transmission.


• Compatibility: Dexron VI is backward compatible with earlier Dexron fluids, making it a versatile choice for those who may have older vehicles or are considering future purchases.


• Fuel Efficiency: The formulation of Dexron VI helps improve fuel efficiency by reducing friction within the transmission, allowing for smoother shifts and less energy loss.

Specifications You Should Know

When selecting transmission fluid, it’s crucial to pay attention to the specifications to ensure compatibility and performance. Here are the key specifications for Dexron VI:

1. Viscosity: Dexron VI has a viscosity rating that allows it to flow easily at low temperatures while maintaining adequate thickness at high temperatures.


2. Color: Typically, Dexron VI is a red or pink color, which can help you identify it easily in case of leaks.


3. API Rating: Look for fluids that meet or exceed the API (American Petroleum Institute) standards, as this indicates a level of quality and performance.

Checking Fluid Quality

While we won’t dive into dipstick checks, it’s essential to monitor the condition of your transmission fluid. Here are some signs that your fluid may need attention:

• Burnt Smell: If your transmission fluid has a burnt odor, it’s a sign that it may be breaking down and needs to be replaced.


• Dark Color: Fresh transmission fluid is typically a bright red. If it appears dark brown or black, it’s time for a change.


• Slipping Gears: If you notice your transmission slipping or having difficulty shifting, it could be a sign of low or degraded fluid.

Using the right transmission fluid is crucial for the performance and longevity of your 2017 Chevy Impala. Stick to the manufacturer’s recommendations, and you’ll keep your ride smooth and reliable for years to come.

Change Interval for Transmission Fluid

Maintaining your 2017 Chevy Impala’s transmission fluid is essential for ensuring smooth operation and prolonging the life of your vehicle. Understanding the recommended change interval is crucial for keeping your transmission in top shape.

Recommended Change Interval

For the 2017 Chevy Impala, General Motors recommends changing the transmission fluid every 50,000 to 100,000 miles (approximately 80,000 to 160,000 kilometers ), depending on driving conditions and habits. Here are some factors that can influence this interval:

• Driving Conditions: If you frequently drive in stop-and-go traffic, tow heavy loads, or operate in extreme temperatures, you may need to change your fluid more often.


• Fluid Quality: The quality of the transmission fluid can also affect how often it needs to be changed. Higher-quality fluids may last longer, while lower-quality options may degrade more quickly.


• Vehicle Usage: If your Impala is primarily used for short trips, the fluid may not reach optimal operating temperatures, leading to condensation and contamination. In such cases, more frequent changes may be necessary.

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. However, partial transmission oil changes can be a practical alternative for maintaining fluid quality without the need for a full removal.

What is a Partial Transmission Oil Change?

A partial transmission oil change typically involves draining a portion of the old fluid and replacing it with new fluid. This method can help maintain fluid quality and performance without the extensive labor involved in a full change. Here’s how it works:

1. Drain and Replace: A mechanic will drain a certain amount of fluid (often around 5 to 7 quarts) and replace it with fresh fluid. This helps to dilute any contaminants and degraded fluid in the system.


2. Frequency: Partial changes can be performed more frequently than full changes, allowing for better maintenance of fluid quality over time.

Justification for Partial Changes

Several authoritative sources support the practice of partial transmission oil changes as a viable maintenance strategy:

• Industry Standards: Many automotive experts recommend partial fluid changes as a way to keep transmission systems healthy. The Automotive Service Association (ASA) suggests that regular partial changes can help extend the life of the transmission.


• Statistical Data: According to a study by the American Automobile Association (AAA), vehicles that undergo regular maintenance, including partial fluid changes, experience fewer transmission-related issues and have lower repair costs over time.


• Owner Feedback: Many vehicle owners report positive experiences with partial changes, noting improved shifting performance and reduced transmission problems. This anecdotal evidence aligns with the recommendations from automotive professionals.

Understanding the change interval for your transmission fluid and considering partial changes can help you maintain your 2017 Chevy Impala effectively. Regular maintenance is key to ensuring your vehicle runs smoothly and reliably for years to come.
