What is transfer case fluid used for?
In four-wheel drive and all-wheel drive (4WD and AWD) cars, a transfer case is and important drivetrain component. It is used to direct power from the transmission to all four wheels. This lets all wheels have power at the same time, or lets the control when four-wheel drive is activated.

In order for the transfer case to function normally, it needs to remain lubricated. If it is not, premature wear and damage can occur. Transfer case fluid lubricates the various moving gears, belts or chains. This allows the parts to move smoothly, preventing overheating and wearing caused by excess friction.
When to replace transfer case fluid?
The exact interval in which transfer case fluid should be replaced depends on several factors such as the make and model of your vehicle, the type of transfer case fluid used, and driving conditions.
Generally, it is recommended to replace transfer case fluid every 50,000 to 100,000 km (30,000 to 60,000 miles) or as specified by the manufacturer in the car’s owner’s manual.
It is important to routinely check the fluid levels and condition, and to have the fluid changed if it appears dirty or discolored, or if you experience any slipping, grinding, or unusual noises in the transfer case.
If you drive in severe conditions such as off-road, in extreme temperatures, or in heavy traffic, you may need to replace the fluid more frequently.
Symptoms of dirty transfer case fluid:
There are several symptoms that point to transfer case fluid being due for a replacement. Below are some of the most commons symptoms:
- Loud noises when driving – When a transfer case is not lubricated properly, you could hear loud grinding noises as you drive. These noises may become worse when four-wheel drive is engaged.
- Visible leaks – Leaks in the transfer case will deplete it of fluid, resulting in a lack of lubrication. If you notice puddles forming under your car, we recommend that you get your can examined sooner rather than later.
- Problems shifting gears – Low transfer case fluid can affect your transmission’s ability to shift gears. It can also cause your car to fall out of four-wheel drive.
How to check transfer fluid
To check the transfer case fluid, you will need to follow these steps:
- Park the vehicle on level ground: Make sure that the vehicle is parked on a level surface to get an accurate reading of the fluid level.
- Find the transfer case: The transfer case is often located near the center of the vehicle and is connected to the transmission. It is usually identified by a removable fill plug or a dipstick. Consult your car’s manual if you are unsure.
- Remove the fill plug or dipstick: Use a ratchet or wrench to remove the fill plug or dipstick. If the vehicle has a dipstick, wipe it clean with a clean cloth and reinsert it into the transfer case.
- Check the fluid levels: If the vehicle has a dipstick, check the fluid level by removing the dipstick and reading the level marked on it. If the vehicle has a fill plug, you can check the fluid level by looking at the fluid that is visible through the fill hole. The fluid level should be between the “full” and “add” marks on the dipstick, or should be visible near the top of the fill hole.
- Inspect the fluid: Check the color and condition of the fluid. The fluid should be clear with a reddish tint, similar to that of engine oil. If the fluid is dirty or discolored, it may indicate a problem and should be changed.
