How much oil does a 2008 Toyota Tundra transfer case hold?
The transfer case in a 2008 Toyota Tundra holds about 1.9 quarts (roughly 1.8 liters) of gear oil when drained and refilled. This is the typical capacity for the model, though the exact amount can vary slightly depending on the specific transfer-case variant and service procedure. Always confirm with the factory service information for your vehicle.
Understanding the capacity and its importance
Knowing the correct capacity helps ensure you fill the transfer case to the proper level, avoiding under- or over-filling, which can affect performance and long-term reliability. The 2008 Tundra uses a two-speed transfer case in its 4WD system, and the 1.9-quart figure is the standard drain-and-fill capacity most owners use when performing routine maintenance.
Key facts about the 2008 Tundra transfer case
Capacity figures are provided by Toyota’s service data and may vary slightly with production changes or between different build options. For the most precise requirement, consult the official service manual for your truck’s VIN or contact a Toyota dealer. In practice, many owners use roughly 1.9 quarts (1.8 liters) of SAE 75W-90 GL-4 gear oil for a complete drain-and-fill when performing routine maintenance.
Before beginning any service procedure, prepare with the right tools and fluids, and follow safe lifting and jacking procedures to protect yourself and the vehicle.
Below is guidance to help you perform a drain-and-fill and to understand the material needs for the job.
Steps to drain and refill the transfer case
- Position the vehicle on level ground, engage parking brake, and safely raise and support the truck if needed. Locate the transfer case fill and drain plugs.
- Remove the fill plug first to ensure you can refill the case after draining; this helps prevent a situation where the case cannot be refilled if the drain plug becomes clogged.
- Place a suitable drain pan underneath and remove the drain plug to allow the old oil to drain completely.
- Inspect and clean the drain plug and replace the washer if necessary before reinstalling it securely.
- Reinstall the drain plug after drainage, then remove the fill plug and slowly add the recommended gear oil until it begins to seep from the fill hole.
- Reinstall the fill plug, wipe up any spills, lower the vehicle, and check for leaks after a short test drive. Recheck the level if needed.
Concluding the drain-and-fill process with the correct amount helps maintain proper lubrication and transfer-case performance. The typical capacity of about 1.9 quarts serves as a practical guideline for most 2008 Tundra vehicles, but always verify against your manual.
Tools and fluids for the job
- Gear oil: SAE 75W-90 GL-4 (or the Toyota-recommended equivalent) for transfer cases.
- Drain pan, funnel, and rags for cleanup.
- Wrenches or sockets to remove the fill and drain plugs; washer or crush washer as required.
- Approximately 1.9 quarts (1.8 liters) of oil as the target fill amount.
Concluding guidance on materials ensures you shop with the correct lubricant and the right fittings to minimize leaks and improvised repairs. Always consult the official manual for the exact specification for your VIN.
Common pitfalls to avoid
- Overfilling the transfer case, which can cause foaming and leaks.
- Using the wrong oil grade (some transmissions use GL-4; avoid GL-5 unless specified).
- Forgetting to reinstall or properly seal the fill plug, which can lead to loss of oil and contamination.
- Not checking for leaks after the refill and test drive; re-check the fluid level and plugs as needed.
Concluding cautions emphasize following the exact spec for your truck, as variations can occur based on production changes and optional equipment. When in doubt, verify with Toyota’s official service documentation or a qualified technician.
Summary
The 2008 Toyota Tundra transfer case typically holds about 1.9 quarts (≈1.8 liters) of gear oil for a standard drain-and-fill. Use the recommended gear oil (commonly SAE 75W-90 GL-4 or an equivalent), follow a careful drain-and-fill routine, and verify the level after completion. Always refer to the factory service manual for your specific VIN to confirm the exact capacity and procedure.
