What fluid to put in a GM transfer case?
When it comes to maintaining your GM vehicle, ensuring the proper fluid is used in the transfer case is crucial for optimal performance and longevity. The transfer case plays a vital role in distributing power from the transmission to the front and rear axles, especially in four-wheel-drive and all-wheel-drive systems. Using the correct fluid not only ensures smooth operation but also prevents costly repairs down the road.
Understanding GM Transfer Case Fluid Requirements
General Motors (GM) vehicles are designed with specific requirements for transfer case fluids. The type of fluid you need depends on the model and year of your vehicle. GM has developed its own transfer case fluid, known as Auto-Trak II, which is specifically formulated for many of their vehicles. However, it’s essential to consult your owner’s manual or a trusted mechanic to confirm the exact fluid type for your specific model.
Why Using the Correct Fluid Matters
Using the wrong fluid in your GM transfer case can lead to a variety of issues, including poor performance, increased wear and tear, and even complete failure
As the owner of Kevin's Autos, an auto service shop with years of experience in car maintenance and repair, I'm often asked about the proper fluids to use in various vehicle components. One common question is what fluid to put in a GM transfer case. In this article, I'll provide a detailed answer to help you keep your GM vehicle's transfer case in top condition.
What is a Transfer Case?
A transfer case is a component found in four-wheel-drive (4WD) and all-wheel-drive (AWD) vehicles. It's responsible for distributing power from the transmission to the front and rear axles, allowing the vehicle to operate in different drive modes, such as 2WD, 4WD, and low-range 4WD.
Recommended Fluid for GM Transfer Cases
The recommended fluid for GM transfer cases is a specialized transfer case fluid. GM specifies the use of Dexron-III/Mercon automatic transmission fluid or an equivalent fluid that meets the GM 9986195 specification.
It's important to use the correct fluid, as the transfer case requires a specific type of lubricant to function properly. Using the wrong fluid can lead to premature wear, leaks, and even damage to the transfer case components.
Fluid Change Intervals
GM recommends changing the transfer case fluid every 30,000 to 60,000 miles, or as specified in the vehicle's owner's manual.p>
It's a good idea to check the fluid level and condition regularly, as well. If the fluid appears dirty or contaminated, it's best to have it changed sooner.
Fluid Capacity
The fluid capacity for GM transfer cases can vary depending on the specific model and year of the vehicle. Typical transfer case fluid capacities range from 1.5 to 3 quarts.
Be sure to refer to your vehicle's owner's manual or consult with a professional technician to determine the correct fluid capacity for your GM transfer case.
Conclusion
Maintaining the proper fluid in your GM transfer case is crucial for its long-term performance and reliability. By using the recommended Dexron-III/Mercon or equivalent fluid and following the manufacturer's recommended change intervals, you can help ensure your 4WD or AWD vehicle continues to operate smoothly for years to come.
Frequently Asked Questions
What kind of oil do you use in a transfer case?
Most transfer cases are filled with an automatic transmission fluid, which is usually red in colour. Others use a thicker gear oil, and some use a specialized fluid that is specifically made just for that transfer case.
What's the difference between transmission fluid and transfer case fluid?
Transfer case fluid is usually blue, brown, green, or yellow. Meanwhile, transmission fluid designed for use in the transfer case is often a clear fluid with hues of dark red. In comparison, fresh transmission oil is usually red in color. If the lubricant becomes contaminated, its color changes to black or brown.
Is transfer case fluid different than transmission fluid?
Both fluids serve as cooling lubricants for their respective systems. However, the two lubricants are different. While some transfer cases use automatic transmission fluid instead of dedicated transfer case fluid, the two are generally not interchangeable.
What type of ATF does GM use?
DEXRON
DEXRON. DEXRON is the trade name for a group of technical specifications for automatic transmission fluid (ATF) created by General Motors (GM). The name was first registered as a trademark and later evolved into a brand of GM.

What fluid does a 2000 Chevy Silverado transfer case take?
Transfer Case and Differential Fluid Change
| Manual transfer case fluid type | |
|---|---|
| Front | |
| Selectable 4WD | SAE 80W90 GL-5 gear oil |
| Full-time 4WD | SAE 75W90 synthetic gear oil |
| Rear | SAE 75W90 synthetic gear oil |
Can I use ATF in a transfer case?
Automatic Transmission Fluid (ATF) is designed primarily for automatic transmissions. However, in some vehicles, ATF is also used in the transfer case because it handles hydraulic pressure well and operates efficiently in a wide range of temperatures.
