What fluid do I put in my transfer case?
As a vehicle owner, understanding the various fluids that keep your car running smoothly is essential. One critical component of your vehicle's drivetrain is the transfer case, which is responsible for distributing power from the transmission to the front and rear axles. Knowing what fluid to use in your transfer case can help ensure its longevity and optimal performance. In this article, we will explore the types of fluids suitable for transfer cases and provide tips on how to maintain this vital component.
Types of Transfer Case Fluids
Transfer cases typically require specific types of fluids, which can vary based on the make and model of your vehicle. Here are the most common types:
- Automatic Transmission Fluid (ATF): Many transfer cases use ATF, particularly those found in vehicles with automatic transmissions. It's crucial to check your owner's manual to confirm the correct type.
- Gear Oil: Some transfer cases, especially those in heavy-duty trucks or off-road vehicles, may require gear oil. This fluid is thicker and provides better lubrication under extreme conditions.
- Transfer Case Fluid: Certain manufacturers recommend a specific transfer case fluid designed for their vehicles. Always refer to your owner's manual for the exact specifications.
How to Check and Change Transfer Case Fluid
Maintaining the correct fluid level in your transfer case is vital for its performance. Here’s how to check and change the fluid:
- Locate the Fill Plug: The fill plug is usually located on the side of the transfer case. Make sure the vehicle is on a level surface.
- Check Fluid Level: Remove the fill plug and insert your finger into the hole. The fluid should be level with the bottom of the hole. If it’s low, you’ll need to add more fluid.
- Drain Old Fluid: To change the fluid, remove the drain plug and let the old fluid drain completely into a container.
- Add New Fluid: Replace the drain plug and use a funnel to add the appropriate fluid through the fill hole until it starts to seep out.
- Replace Fill Plug: Once the fluid is at the correct level, replace the fill plug securely.
Conclusion
Choosing the right fluid for your transfer case is crucial for maintaining your vehicle's performance and longevity. Always refer to your owner's manual for specific recommendations and consider consulting a professional mechanic if you're unsure. Regular maintenance of your transfer case fluid can prevent costly repairs down the line and ensure a smooth driving experience.
Frequently Asked Questions
What type of fluid goes in a transfer case?
automatic transmission fluid
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.
How do you fill a fluid transfer case?
And clean any spills with a rag disposing of used oil and fluids incorrectly can pollute land water and infrastructure. So it's essential that you dispose or recycle. Used oil correctly.
How do I add fluid to my transfer case?

What happens if you don't change transfer case fluid?
Why is Changing Transfer Case Fluid So Important? Over time, the transfer case fluid deteriorates. Heat and mechanical wear take their toll, diminishing the fluid's effectiveness. This leads to increased friction among components, overheating, and accelerated wear and tear.
Can I use 80W90 instead of 85W90?
If your vehicle is regularly exposed to very cold temperatures, we recommend 80W90 transmission oil, otherwise 85W90 can also be filled in. The performance parameters of the oils of both SAE classes are identical in many respects.
Does transfer case fluid matter?
Regular transfer case fluid changes can help to ensure that the transfer case is operating properly and can extend its lifespan.
Can I use transmission fluid in a transfer case?
Transfer case is not picky at all. You can run any ATF, you can also run motor oil or a light gear oil. It really just needs lubrication and ATF is a lightweight one that does the job. No need to be concerned about what brand.
Can you use 80w-90 in a transfer case?
Yes you can. 75w-90 is usually a synthetic or semisynthetic. 80-90 hardly ever is in the stores. I run 75w-140 in the rear and 75w-90 everywhere else.
How much gear oil do you put in a transfer case?
We need 1.5 quarts of gear oil. We went with AMSOIL severe gear SAE 75 90 synthetic extreme pressure lubricant formulated for severe duty applications.
What happens if you run out of transfer case fluid?
You may be able to drive a short distance because of residual fluid in the case, but continued attempts to drive will damage the transmission, whether it is a manual or automatic transmission.
