Toyota Tundra Transfer Case Fluid Specification Guide
How to Find Your Toyota Transfer Case Fluid Type?
Currently, in the United States, the Toyota Tundra is optioned with two types of transfer case fluids. The two transfer case fluids are different Toyota fluid part numbers, specifications, and viscosity types. The type of transfer case fluid you will need depends on the exact year of your Toyota Tundra. Below is a brief description of the Toyota Tundra transfer case fluid options.
Toyota Tundra 75W Transfer Case Fluid
In the United States, Toyota started using transfer case fluid part number 08885-81080 in the Toyota Tundra 4WD models in 2013. The 75W is an updated formulation compared to the standard 75W-90 gear oil that was originally recommended in the 2012 and older Toyota Tundra 4WD models. Toyota transfer case fluid part number 08885-81080 is a 75W viscosity and does not specifically identify with any GL (gear lube) specification like the older recommended gear oils (e.g. GL-5).
The main reason Toyota chose to update to the 75W transfer case fluid was to improve the vehicle's efficiency. By using a 75W transfer case fluid (vs the 75W-90), Toyota was able to improve the rolling resistance of the vehicle. This allows for less dynamic drag inside the transfer case resulting in improved fuel economy. The Toyota 75W transfer case fluid offers better lubrication and flow to key areas of the transfer case. It also supplies better cold climate lubrication.
Some still choose to use 75W-90 gear oil even though the Toyota 75W transfer case fluid is specified. We feel this is illogical. The newer Toyota 75W transfer case fluid specification contains a more involved additive formulation, uses higher quality additives, and advanced fully synthetic base oils when compared to the popular entry-level 75W-90 gear oils. The high-quality level of the Toyota 75W transfer case fluid formulation achieves the benefits of instantaneous quick lubricating flow, as well as, keeping excellent shear stability in high load heavy heat driving conditions.
Toyota Tundra 75W Transfer Case Fluid Part Numbers & Fitments
The Toyota 75W transfer case fluid can also be identified by more than one part number. As many know Toyota has several divisions that operate in a variety of regions worldwide to support their automotive network. These different Toyota transfer case fluid part numbers are dependent on the regional location or country.
- Toyota transfer case fluid part number 08885-81080 is known and identified as the USA and Japanese regional part number.
- Toyota also identifies the 75W transfer case fluid under part number 08885-81081. Part number 08885-81081 is used for the Toyota Europe region.
Toyota Tundra 4WD models require 75W transfer case fluid part numbers 08885-81080 and 08885-81081. These transfer case fluid applications apply to models available in America only.
Eurol MTF 75W and Ravenol MTF-3 75W is an equivalent replacement for both Toyota transfer case fluid part numbers 08885-81080 and 08885-81081 for the following Toyota Tundra 4WD model fitments.
- 2013-2021 Toyota Tundra 4WD 5.7L V8 gasoline models use 08885-81080 or 08885-81081 transfer case fluid.
- 2013-2019 Toyota Tundra 4WD 4.6L V8 gasoline models use 08885-81080 or 08885-81081 transfer case fluid.
Toyota Tundra 75W-90 Transfer Case Fluid
The 2012 and older Toyota Tundra 4WD models use SAE 75W-90 viscosity gear oil with an API GL-4 or GL-5 specification in the transfer case.
Some view a 75W-90 gear oil as a popular, universal, or generic specification. However, we recommend using a 75W-90 GL-4 or GL-5 gear oil for this application that specifically says it is compatible with or should be used in transfer cases. Also, for the best transfer case longevity and performance, the 75W-90 gear oil should be made of a fully synthetic base oil formulation.
Toyota Tundra 75W-90 Transfer Case Fluid Part Numbers & Fitments
2Toyota references several different SAE 75W-90 gear oil part numbers that can be used for these transfer case applications.
- Toyota part numbers 08885-02106, 08885-80606, 08885-81026, 08885-81520.
Toyota Tundra 4WD models requiring 75W-90 transfer case gear oil part number 08885-02106, 08885-80606, 08885-81026, or 08885-81520. These transfer case fluid applications apply to models available in America only.

Toyota Tundra Transfer Case Fluid Change Intervals
When should you change your Toyota Tundra center transfer case fluid? We recommend changing the fluid around 80,000-90,000 miles. However, the transfer case fluid should be changed depending on your driving style. If the vehicle sees aggressive driving, consistent 4WD engagement, off-roading, and consistent trailer pulling you should service the center transfer case fluid more frequently and as early as every 40,000-50,000 miles. Abiding by these recommended transfer case fluid change intervals can eliminate and minimize transfer case issues and costly repairs.
Why Should Toyota Tundra Transfer Case Fluid Be Changed?
The Toyota Tundra center transfer case has a good amount of moving internal components. This includes bearings, sprockets, gears, gear pulleys, and chains. These internal components rely solely on the transfer case fluids lubrication film strength for protection and longevity. Through use, the center transfer case fluid experiences excessive shear loads and excessive heat cycles. In time these heat cycles and excessive loads deplete the lubricating properties and film strength of the center transfer case fluid. Continued use of old transfer case fluid will result in transfer case bearing, bearings, sprockets, gears, gear pulleys, chain wear, and possible failure. Therefore, having regular transfer case fluid changes is important. Changing the center transfer case fluid as routine maintenance will greatly extend the life of the transfer case, minimize driveline noises, poor 4WD engagement, chatter, and vibrations due to wear, and ensure the transfer case unit receives reliable clean lubrication.
