What kind of oil does a Tacoma transfer case take?

The transfer case in most Toyota Tacoma models uses automatic transmission fluid (ATF), not engine oil or gear oil. The exact ATF specification depends on the vehicle’s year and transfer-case variant.

Understanding transfer-case fluid requirements

In a Toyota Tacoma, the transfer case is lubricated with ATF rather than standard gear oil. The reason for ATF is its friction characteristics, heat management, and anti-foaming properties, which suit the transfer-case action and engagement. Different model years and transfer-case designs may call for slightly different ATF formulations, so the precise specification can vary.

To avoid using the wrong fluid, always check the owner’s manual or contact a Toyota dealer for the exact specification for your vehicle. Using an incompatible fluid can cause shifting problems, noise, or transfer-case damage over time.

Common ATF options by era

Here are the ATF options you might encounter on Tacomas, depending on year and transfer-case configuration. This is a guide rather than a guarantee for every individual vehicle.

• Dexron II/III Automatic Transmission Fluid (ATF) — commonly referenced for older Tacomas and earlier transfer-case service intervals.


• Dexron VI ATF — widely used in many late-model Tacomas and a frequent recommendation for replacement in newer vehicles that originally used Dexron II/III.


• Toyota ATF WS (World Standard) — used in some later-model Toyota automatic transmissions and transfer cases; may be listed as compatible in certain years.


• Toyota Type T-IV ATF — found in some older Toyota applications and may appear in service documentation for certain models; verify applicability to your specific Tacoma.

Bottom line: ATF is the generic category, but the exact formulation should be confirmed for your year and transfer-case version. When in doubt, use the fluid specified in your owner's manual or by a Toyota service advisor.

How to confirm the exact specification for your Tacoma

To ensure you source the correct transfer-case fluid, follow these steps. They will help you verify the correct ATF type for your vehicle.

1. Check the owner’s manual — look under the maintenance or specifications section for the transfer-case fluid type and approved fluids.


2. Inspect the transfer-case fill plug or the under-hood sticker/label — some Tacomas have the recommended fluid type printed on the transfer-case nearby or on a service sticker.


3. Contact a Toyota dealer or certified shop — provide your VIN to confirm the exact specification for your year and model.


4. Use a compatible ATF if you cannot access the manual — when in doubt, choose a modern ATF that is explicitly listed as compatible with Toyota WS or the Dexron VI family, and avoid non-Toyota specialty fluids unless approved.

Failing to use the correct ATF can lead to improper engagement, increased wear, or damage over time. Always verify before purchasing or servicing the transfer case.

Summary

In short, a Toyota Tacoma transfer case typically takes automatic transmission fluid (ATF), not engine oil or gear oil. The exact ATF specification varies by year and transfer-case design, with common options including Dexron II/III, Dexron VI, and Toyota WS in different eras. Always consult the owner’s manual or a Toyota dealership to confirm the correct fluid for your specific vehicle, and follow the recommended service guidance to protect the transfer-case performance and longevity.

What kind of fluid goes in a Toyota Tacoma transfer case?

The correct Toyota Tacoma transfer case fluid depends on the model year, but it's generally a 75W viscosity fluid. Newer models (2016+) often use Toyota's specific LF 75W fluid (part number 08885-01806 or 08885-81080/81). Older models (1995-2004) and some others may require a 75W90 GL-4 gear oil due to the use of brass synchro rings.

Fluid types by model year

• 2016-2023 and newer: Use Toyota LF 75W transfer case fluid (part number 08885-01806 or 08885-81080/81). 
• 2009-2015: 75W-90 gear oil is recommended. 
• 1995-2004: Use a 75W90 GL-4 gear oil (also called synchro mesh fluid) for the transfer case and manual transmission. 

Important considerations

• GL-4 vs. GL-5: The transfer case in many Tacomas has brass synchro rings, which require a GL-4 rated fluid to prevent damage. Standard GL-5 fluid can harm these components. 
• Manual transmission: If you also have a manual transmission, it also requires a GL-4 fluid, and the same 75W90 GL-4 oil can often be used for both. 
• Check your owner's manual: Always confirm the specific fluid type and quantity in your vehicle's owner's manual for your exact year and model. 

How much oil does a 2019 Toyota Tacoma transfer case hold?

The 2019 Tacoma transfer case fluid capacity is 1.0 liter or approximately 1.05 quarts. It requires a special 75W transfer case fluid, not the same gear oil used in the differentials.

• Capacity: 1.0 liter or 1.05 quarts 
• Fluid Type: 75W transfer case fluid (e.g., Toyota Transfer Gear oil LF 75W or an equivalent) 
• Important: Do not use the same fluid that you use for the front and rear differentials.

Can I use 75w90 instead of 75W85 Toyota?

Yes, you can generally use 75W-90 instead of 75W-85 for most Toyota differentials, as the 75W-90 is a widely available and acceptable substitute. The main difference is that 75W-90 is slightly thicker at operating temperatures, but many mechanics and Toyota dealerships use it as a substitute because it's more common. It's crucial, however, to ensure the new fluid meets the correct GL rating (such as GL-5) for your vehicle's differential, as this is more important than the exact weight. 
Key considerations

• Availability: 75W-85 is less common, making 75W-90 a practical alternative that is readily available at most auto parts stores. 
• Viscosity: While 75W-90 is a bit thicker than 75W-85 at high temperatures, the difference is minimal and won't cause harm in most cases. Some sources even suggest that 75W-90 is preferable for heavy towing, although this is not always the case. 
• GL rating: The most critical factor is the gear oil's GL rating, which specifies its suitability for different types of gears. Make sure the 75W-90 fluid you choose is compatible with your vehicle's requirements (e.g., GL-5 for most differentials). 
• Additives: Be mindful of the additives, particularly for differentials with electronic lockers. Some oils may have anti-wear additives that can harm these components. It's best to stick to a fluid that is specified for your differential type. 
• Performance: You might notice a slight decrease in fuel efficiency with the thicker 75W-90 fluid compared to the OEM 75W-85. However, this difference is usually minimal. 

Recommendation

• If you can't find the 75W-85, a high-quality 75W-90 synthetic gear oil with the correct GL-5 rating is a perfectly acceptable substitute for most Toyota differentials. 
• Some older or specific models might require a GL-4 rating for the transmission. Double-check your owner's manual to confirm the correct GL rating before making a purchase. 

What is Toyota transfer case fluid?

Transfer case fluid is the lubricant for the transfer case of four-wheel drive (4WD) vehicles. Transfer cases are present in cars, SUVs, and trucks with 4WD or all-wheel drive (AWD) modes. Some experts recommend changing the transfer case fluid every 20,000-30,000 miles.
