What fluid to put in a GM transfer case?
The recommended fluid for a GM transfer case is a specialized transfer case fluid. This fluid is designed to provide the necessary lubrication and protection for the gears and components within the transfer case, which is a critical part of a four-wheel-drive or all-wheel-drive vehicle's drivetrain.
Understanding the GM Transfer Case
The transfer case is responsible for distributing power from the transmission to the front and rear axles in four-wheel-drive and all-wheel-drive vehicles. It contains a set of gears and clutches that allow the driver to engage or disengage the front axle, providing the ability to switch between two-wheel-drive and four-wheel-drive modes.
Due to the specialized nature of the transfer case's components, it is important to use the correct fluid to ensure proper lubrication and prevent premature wear or damage. Using the wrong fluid can lead to issues such as gear wear, bearing failure, and even complete transfer case failure.
Recommended Fluid for GM Transfer Cases
The recommended fluid for GM transfer cases is a specialized transfer case fluid that meets the GM specification GM4638M. This fluid is designed to provide the necessary lubrication and protection for the gears, bearings, and other components within the transfer case.
Some key characteristics of the recommended GM transfer case fluid include:
- Viscosity: The fluid has a specific viscosity range that ensures proper lubrication at different operating temperatures.
- Additives: The fluid contains additives that help prevent wear, corrosion, and foaming, which can all contribute to transfer case issues.
- Compatibility: The fluid is specifically formulated to be compatible with the materials and components used in GM transfer cases.
It is important to use the recommended GM transfer case fluid and to follow the manufacturer's recommended service intervals for fluid changes to ensure the long-term health and performance of the transfer case.
Conclusion
In summary, the recommended fluid for a GM transfer case is a specialized transfer case fluid that meets the GM4638M specification. Using the correct fluid is crucial for the proper lubrication and protection of the transfer case's critical components, helping to prevent premature wear and failure.
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 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 |
Is the transfer case fluid the same as 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 happens if you use the wrong ATF?
Immediate Effects. Immediately after putting the wrong transmission fluid in your vehicle, you can start noticing issues while driving. In most cases, people notice strange noises, overheating, and slipping gears. Do not ignore these warning signs, because they will not go away on their own.
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.
What oil goes in a Chevy Silverado transfer case?
Its just Dexron VI.
Is transfer case fluid different than transmission fluid?

What fluid to use in GM transfer case?
The solution? Merchant Automotive Performance Transfer Case Fluid. We've designed this product to be a direct substitute for the factory fill and it blended specifically for use in GM trucks but it may be used in Ford, and Chrysler trucks as well.
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.
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.
