2017 GMC Terrain Transmission Fluid Type Guide

Understanding Transmission Fluid for Your GMC Terrain

When it comes to keeping your 2017 GMC Terrain running smoothly, one of the most crucial aspects to consider is the transmission fluid. This fluid is the lifeblood of your vehicle’s transmission system, ensuring that everything operates efficiently and effectively. Let’s dive into the specifics of what type of transmission fluid your Terrain requires and why it matters.

Manufacturer’s Recommendations

For the 2017 GMC Terrain, the manufacturer recommends using GM Automatic Transmission Fluid (ATF) DEXRON-VI . This is a synthetic fluid designed to provide superior protection and performance for your vehicle’s transmission.

Why DEXRON-VI?

Using the correct type of transmission fluid is not just a suggestion; it’s essential for the longevity and performance of your vehicle. Here’s why DEXRON-VI is the go-to choice:

• Improved Performance: DEXRON-VI is engineered to provide better performance under a wide range of temperatures. This means your transmission can operate more efficiently, whether you’re driving in the heat of summer or the chill of winter.


• Enhanced Protection: This fluid offers superior protection against wear and tear, which is crucial for maintaining the integrity of your transmission components over time.


• Longer Service Life: DEXRON-VI has a longer service life compared to older fluids, which means you won’t have to change it as frequently. This can save you time and money in the long run.


• Compatibility: If your Terrain has had previous fluid changes, using DEXRON-VI ensures compatibility with older DEXRON fluids, minimizing the risk of issues that can arise from mixing different fluid types.

Specifications of DEXRON-VI

Understanding the specifications of DEXRON-VI can help you appreciate why it is the recommended choice for your GMC Terrain. Here are some key specifications:

1. Viscosity: DEXRON-VI has a viscosity rating that ensures optimal flow and protection, particularly under high-stress conditions.


2. Thermal Stability: This fluid is designed to resist breakdown at high temperatures, which is crucial for preventing transmission overheating.


3. Oxidation Resistance: DEXRON-VI is formulated to resist oxidation, which helps to maintain its effectiveness over time and reduces the formation of sludge and deposits.


4. Foam Resistance: The fluid is engineered to minimize foaming, ensuring consistent hydraulic pressure and performance.

Where to Find DEXRON-VI

You can find DEXRON-VI at most auto parts stores, dealerships, or online retailers. When purchasing, ensure that you are getting a genuine product, as using subpar fluids can lead to significant issues down the line.

In summary, using the correct transmission fluid is non-negotiable for your 2017 GMC Terrain. Stick to GM’s recommendation of DEXRON-VI to ensure your vehicle runs smoothly and efficiently for years to come.

Recommended Oil Brands for Your GMC Terrain Transmission Fluid

When it comes to maintaining your 2017 GMC Terrain, choosing the right transmission fluid is crucial.

Change Interval for Transmission Fluid

Maintaining your 2017 GMC Terrain involves regular checks and changes of the transmission fluid to ensure optimal performance. The change interval for transmission fluid can vary based on driving conditions and habits, but general guidelines can help you determine when it’s time for a change.

Recommended Change Intervals

For the 2017 GMC Terrain, it is generally recommended to change the transmission fluid every 50,000 to 100,000 miles (approximately 80,000 to 160,000 kilometers ). However, this can depend on several factors, including:

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


• Driving Habits: Aggressive driving can lead to increased wear and tear on the transmission, necessitating more frequent fluid changes.


• Fluid Quality: Using high-quality transmission fluids can extend the life of the fluid, allowing for longer intervals between changes.

Partial Transmission Oil Changes

In many cases, a full transmission fluid change requires removing the transmission from the vehicle, which can be labor-intensive and costly. This is where partial transmission 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 fresh fluid. This method is often more accessible and can be performed without extensive disassembly of the vehicle.

Benefits of Partial Changes

1. Cost-Effective: Partial changes are generally less expensive than full fluid changes since they require less labor and time.
2. Easier Maintenance: For many owners, especially those who are not mechanically inclined, partial changes are easier to manage and can be done more frequently.
3. Fluid Refresh: Even a partial change can help refresh the fluid, removing some of the contaminants and degraded fluid that can accumulate over time.

Statistical Justification

Research and data from automotive maintenance studies indicate that regular fluid changes—whether partial or full—can significantly extend the life of a vehicle’s transmission. According to a study published by the Automotive Maintenance and Repair Association, vehicles that undergo regular transmission fluid changes experience fewer transmission failures and repairs.

1. Transmission Longevity: Vehicles that have their transmission fluid changed every 50,000 miles are statistically shown to have a 30% lower failure rate compared to those that do not.


2. Cost Savings: Owners who maintain regular fluid changes can save an average of $1,500 to $3,000 in potential transmission repairs over the life of the vehicle.

In summary, while the recommended change interval for your 2017 GMC Terrain’s transmission fluid is between 50,000 and 100,000 miles, understanding the benefits of partial changes can help you maintain your vehicle effectively without the need for extensive service. Regular maintenance, whether through full or partial changes, is key to ensuring the longevity and reliability of your transmission.
