How to Choose the Right Fluid for Your Transfer Case
Choosing the Right Fluid for Your Transfer Case
Transfer cases are an essential component of four-wheel drive (4WD) and all-wheel drive (AWD) vehicles. They distribute power from the transmission to the front and rear axles, allowing the driver to switch between two-wheel drive and four-wheel drive modes.
GL-4 Gear Lube
GL-4 gear lube, such as SAE 80W-90, is commonly used in manual transmissions and differential gear boxes. Some transfer cases are designed to use GL-4 gear lube as well. This type of gear lube provides the necessary lubrication and protection for the gears within the transfer case.
Automatic Transmission Fluid (ATF)
Automatic transmission fluid (ATF) is also suitable for certain transfer cases, especially those that are integrated with the transmission. ATF provides lubrication and heat dissipation properties that are essential for the proper functioning of the transfer case.
Manufacturer's Specifications
When deciding which fluid to use for your transfer case, it is crucial to consult the manufacturer's specifications. The manufacturer will specify the type of fluid that is compatible with your specific make and model of transfer case. Using the wrong type of fluid can lead to performance issues and potential damage to the transfer case.
Final Thoughts
Whether you choose to use GL-4 gear lube or ATF for your transfer case, always prioritize following the manufacturer's recommendations. By using the correct fluid, you can ensure optimal performance and longevity of your transfer case.
