A transfer case is a necessary component of four-wheel drive and all-wheel drive vehicles. This gear system divides power between the front and rear axles to deliver optimal traction.
Transfer cases need fluid for lubrication. The fluid ensures the gears within the transfer case can move smoothly and dissipate heat. In return, the transfer case sustains less wear and shields the transmission from overheating. However, you must know what fluids you can use for your transfer case for the best performance. Continue reading below to find out your options.
Automatic Transmission Fluid
Many modern vehicles with transfer cases require automatic transmission fluid (ATF) for optimal performance. ATF is a specialized lubricant that withstands high temperatures, resists corrosion, and decreases the frequency of fluid changes.
ATF contains detergents and additives to prevent build-up and keep the transfer case clean. Its unique formulation ensures smooth operation and protects vital components from wear and tear.
Gear Oil
Gear oil possesses a thicker consistency than ATF. This high-viscosity fluid can withstand high pressure and extreme temperatures. It’s ideal for heavy-duty vehicles and older automobiles. Gear oil is a durable protective layer that reduces friction and wear.
Gear oil includes additives that prevent oxidation and corrosion to maintain the performance and lifespan of the transfer case, safeguarding your vehicle's transmission system. Remember to check the vehicle's owner’s manual before adding gear oil to the transfer case.
Specialty Lubricants
Vehicle manufacturers develop specialty lubricants to meet the specifications of a vehicle's make and model. These lubricants offer optimal performance, provide superior lubrication, and ensure the smooth operation of the transfer case.
Specialty lubricants have additional benefits, such as enhanced thermal stability, improved wear protection, and extended fluid life. They can reduce noise and vibration to provide a smooth ride.
Note that these lubricants tend to be more expensive than standard ATF or gear oil. Despite the cost, the investment can be worthwhile for people seeking to optimize their vehicle's performance and lifespan.
