Everything You Need to Know About Valvoline Transfer Case Fluid

In the world of automotive maintenance, transfer case fluid plays a crucial yet often overlooked role in the performance and longevity of vehicles equipped with four-wheel drive (4WD) or all-wheel drive (AWD) systems. One of the most trusted names in lubricants and automotive fluids, Valvoline offers specialized transfer case fluids that help maintain system efficiency and reliability. Whether you're a seasoned mechanic or a vehicle owner aiming for preventive maintenance, understanding what Valvoline transfer case fluid is and how it benefits your vehicle is essential.

What Is Transfer Case Fluid?

Before diving into Valvoline’s specific product range, it’s important to understand the function of transfer case fluid. The transfer case is a vital component in AWD and 4WD vehicles. It distributes power from the transmission to the front and rear axles through the drive shafts. Since this component houses gears and chains that operate under significant pressure and friction, it requires a high-quality lubricant to ensure smooth performance and prevent wear and overheating.

Transfer case fluid is specifically formulated to meet these demands. It lubricates the internal parts, reduces heat buildup, and ensures proper operation of the 4WD or AWD system. Over time, this fluid can degrade due to heat and contamination, leading to potential damage and decreased performance if not changed regularly.

Why Choose Valvoline Transfer Case Fluid?

Valvoline has earned its reputation through decades of innovation and quality in the automotive industry. When it comes to transfer case fluid, the brand offers several advantages:

1. OEM-Approved Formulas

Valvoline’s transfer case fluids are engineered to meet or exceed Original Equipment Manufacturer (OEM) requirements. This ensures compatibility and optimal performance for a wide range of vehicle makes and models, including Ford, GM, Dodge, Toyota, and more.

2. Superior Protection Against Wear

Valvoline fluids are designed with high-performance additives that offer superior wear

protection. This minimizes the risk of metal-to-metal contact within the transfer case, reducing component wear and extending the lifespan of your vehicle’s drivetrain.

3. Excellent Thermal Stability

Operating temperatures inside a transfer case can get quite high, especially in challenging driving conditions like towing or off-roading. Valvoline fluids maintain their viscosity and lubricating properties even under extreme temperatures, providing consistent performance and protection.

4. Outstanding Oxidation Resistance

Oxidation leads to the breakdown of fluid over time. Valvoline transfer case fluid resists oxidation better than many conventional alternatives, which helps maintain fluid integrity and prolong service intervals.

5. Anti-Foaming Properties

Foaming can reduce the fluid's ability to lubricate effectively. Valvoline products include anti-foaming agents to ensure consistent lubrication and pressure distribution within the transfer case.

Types of Valvoline Transfer Case Fluids

Valvoline offers different formulations tailored to specific vehicles and driving needs. Here are some of their most common and widely used options:

1. Valvoline Full Synthetic Transfer Case Fluid

This fully synthetic fluid provides enhanced performance and protection for modern 4WD and AWD systems. It is compatible with many domestic and import vehicles and is designed to operate efficiently in extreme temperatures. It's an ideal choice for vehicles that undergo heavy-duty usage or operate in tough conditions.

2. Valvoline Multi-Vehicle Transfer Case Fluid

Designed to be compatible with a variety of makes and models, this option simplifies fluid selection for multi-vehicle households or service centers. It meets the specifications of many OEMs, including Ford XL-12, GM Auto-Trak II, and Chrysler NV245.

3. Valvoline DEX/MERC ATF (for Older Models)

While not strictly a transfer case fluid, many older vehicles use automatic transmission fluid (ATF) in the transfer case. Valvoline’s DEX/MERC ATF is a high-quality fluid that can be used where the vehicle manual specifies this type of fluid for transfer cases.

Signs You Need to Change Your Transfer Case Fluid

To maintain optimal performance, transfer case fluid should be changed at intervals recommended by the vehicle manufacturer—typically every 30,000 to 60,000 miles. However, here are a few signs that your fluid may be due for a change:

• Strange noises when shifting into 4WD mode

• Difficulty engaging/disengaging 4WD or AWD

• Fluid leaks under the center of the vehicle

• Burning smell from under the vehicle

• Reduced off-road performance

Failing to address these signs can lead to more serious mechanical issues and expensive repairs down the line.

How to Change Valvoline Transfer Case Fluid

Changing transfer case fluid is a relatively straightforward process for those with basic automotive knowledge and tools. However, if you're not confident, it’s best left to a professional mechanic. Here’s a simplified step-by-step overview:

1. Lift the Vehicle: Use a jack and jack stands or a lift to safely raise the vehicle. Ensure it is on a level surface.

2. Locate the Transfer Case: Refer to your owner’s manual to identify the fill and drain plugs.

3. Drain the Old Fluid: Remove the drain plug and allow the old fluid to completely drain into a container.

4. Inspect the Fluid: Check for metal shavings or discoloration, which can indicate internal wear.

5. Reinstall Drain Plug: Once drained, reinstall and tighten the drain plug.

6. Refill with Valvoline Fluid: Using a pump, fill the transfer case through the fill port until the fluid starts to trickle out.

7. Replace Fill Plug: Tighten the fill plug and clean off any spilled fluid.

8. Test Drive: Drive the vehicle briefly to ensure proper operation and check for leaks.

Always dispose of the old fluid responsibly at an automotive recycling center.

Compatibility and Specifications

Valvoline clearly labels each product with the vehicle models and OEM specifications it is designed to meet. Always cross-check with your owner’s manual or consult with a mechanic before choosing the correct fluid. Using the wrong fluid can compromise your drivetrain’s performance and potentially void the warranty.
