Important Fitment Note for 2nd Generation 2009-2015 Models
While this DIY tutorial and video are demonstrated on a 3rd generation Toyota Tacoma, the same general steps apply to 2009-2015 2nd generation Tacoma models with one key difference. The older models have a different recommended fluid type and viscosity. For the exact differences and specific instructions, refer to the "2009-2015 2nd Gen Tacoma" tab in the relevant steps below.
Toyota Tacoma Transfer Case Fluid Change Interval
How often should you change your Toyota Tacoma transfer case fluid? We recommend changing the Tacoma transfer case fluid between 80,000 and 90,000 miles under normal driving conditions. However, if you engage in more demanding driving—such as aggressive driving, frequent 4WD use, off-roading, or towing—it's best to service the Tacoma transfer case fluid more frequently, around every 40,000 to 50,000 miles. Following these recommended intervals can help prevent transfer case issues and costly repairs.
Why Should Toyota Tacoma Transfer Case Fluid Be Changed?
The transfer case in your Toyota Tacoma contains several moving components, including bearings, sprockets, gears, pulleys, and chains. These parts depend entirely on the lubricating strength of the transfer case fluid to reduce friction and prevent wear. Over time, due to heavy shear loads and repeated heat cycles, the transfer case fluid's lubricating properties degrade, weakening its protective film. If the fluid isn't replaced regularly, worn-out fluid can lead to increased wear on bearings, gears, and chains—eventually causing major, and costly failures.
By changing the transfer case fluid as part of your routine maintenance, you effectively extend the life of the transfer case, reduce driveline noise, improve 4WD engagement, and minimize issues like vibrations or chatter caused by wear. Fresh fluid ensures reliable lubrication and helps prevent costly repairs down the road.

Toyota Tacoma Transfer Case Fluid Type Specifications
In the United States, from 2009 to 2023, Toyota Tacoma models used two types of transfer case fluids, differing by part number, specification, and viscosity. The correct fluid depends on your Tacoma's model year:
2016-2023 Toyota Tacoma 4WD models: Use transfer case fluid with part number 08885-01806 (or 08885-81080 or 08885-81081), which has a 75W viscosity.
2009-2015 Toyota Tacoma 4WD models: Use transfer case fluid with part numbers 08885-02106, 08885-80606, 08885-81026, or 08885-81520, all with a 75W-90 viscosity and API GL-4 or GL-5 specification.
Toyota Tacoma Transfer Case Fluid Capacity
The transfer case fluid fill for all 2009-2023 Toyota Tacoma 4WD models is 1.0 liter or 1.05 quarts

Step-by-Step Toyota Tacoma Transfer Case Fluid Change Instructions
Disclaimer: Blauparts recommends having a factory-trained A.S.E. certified Toyota mechanic perform vehicle maintenance. Always refer to the owner's and factory service manuals for Toyota transfer case fluid changing procedures. Always wear protective gloves and wear safety glasses when handling fluids and oils.
Step 1
Begin by confirming the transfer case is warm. This can be done by taking your truck for a quick 10 to 15-minute drive. This will allow the transfer case fluid viscosity to get thinner and flow more easily from the transfer case while it’s being drained.
Step 2
For a proper transfer case fluid change, park your Toyota Tacoma on a flat, level surface. Most Tacomas have enough ground clearance to perform this service without lifting the vehicle. If the vehicle isn’t level, the fluid level could be incorrect, potentially leading to transfer case damage.
Important Note: If you choose to lift the vehicle, use an SAE approved automotive hoist, floor jack, or jack stands. Always refer to your Tacoma's owner's manual for proper lift points and safety procedures.
Step 3
Locate and remove the transfer case fill plug AND sealing washer. This is located on the rear side of the transfer case closest to the driveshaft. Loosen and remove the fill plug AND sealing washer in a counterclockwise direction using a 24mm socket and ratchet. It is always best to confirm the fill plug can be removed before draining the transfer case fluid. This will confirm you will have a way to refill the transfer case with fluid in case the fill plug is seized or can’t be removed.
Step 4
Prepare a waste oil drain pan for the old transfer case fluid, then locate the transfer case fluid drain plug on the rear lower left section of the transfer case. Loosen and remove the drain plug in a counterclockwise direction using a 24mm socket and ratchet.
Allow the old transfer case fluid to thoroughly drain into your waste oil drain pan.
Step 5
Clean and remove any excess fluid, corrosion, contaminants, or debris from both the drain and fill plugs.
Step 6
Once the old Toyota Tacoma transfer case fluid has fully drained, reinstall the drain plug AND sealing washer by threading it in a clockwise direction. Using a 24mm socket and torque wrench, tighten the drain plug to the recommended 27 ft-lbs. torque specification.
Step 7
Begin filling the transfer case through the fill port with the recommended 75W transfer case fluid. Make sure you have your waste oil drain pan container handy to catch the overflow of fluid. The correct fluid level has been achieved when a stream of fluid begins overflowing from the transfer case fluid fill port—this should be around 1.0 liter or 1.05 quarts.
Begin filling the transfer case through the fill port with the recommended 75W-90 transfer case fluid. Make sure you have your waste oil drain pan container handy to catch the overflow of fluid. The correct fluid level has been achieved when a stream of fluid begins overflowing from the transfer case fluid fill port—this should be around 1.0 liter or 1.05 quarts.
Fluid Capacity and Fill Note: Depending on the length of time allowed for the old fluid to drain from the transfer case and the temperature of the fluid at the time of draining, the amount of fluid required to refill the transfer case may vary slightly. After refilling the transfer case with the 1 liter of gear oil provided in our kit, some customers may not experience fluid overflowing out of the fill hole. Even though the Transfer case fluid fill capacity is 1.0 liter or 1.05 quarts, the fluid level in the transfer case may be just shy of overflowing out of the fill hole by only a few millimeters. If you added the entire contents of the 1-liter bottle provided, you can consider the transfer case as being full even though you did not have fluid overflowing out of the fill hole. However, depending on your preference, you may wish to leave it as is or purchase an additional liter of fluid for adding another ounce or two to achieve the fluid overflowing out of the fill hole.
Step 8
After confirming the transfer case fluid level is full, reinstall the fill plug AND sealing washer. Using a 24mm socket and a torque wrench, tighten the fill plug to the recommended 27 ft-lbs torque specification.
Step 9
Using a rag, clean and remove all excess drained and overflowed Toyota Tacoma transfer case fluid from the transfer case drain and fill plug locations. The transfer case should be completely cleaned of all fluid residue. This will later help you to inspect and confirm that the transfer case does not have any leaks.
Step 10
If you chose to lift the vehicle with an approved automotive hoist, floor jack, or jack stands, you can lower the vehicle as highlighted and referenced in your factory owner’s manual. Confirm the correct vehicle lift point locations and procedures are followed as instructed in your factory owner's manual.
Step 11
Once you have the vehicle on the ground you can take the truck for a simple 5 to 10-minute test drive and then examine the Toyota Tacoma transfer case and confirm you do not have any leaks coming from the transfer case drain plug.
Step 12
Dispose of your old transfer case fluid responsibly by taking it to a certified recycling collection center.
Note: It is good to note in your records the current mileage at the time of your transfer case fluid change, as well as when you might want to change it next. We also recommend keeping detailed service records to keep track of your vehicle's true condition. Keeping good vehicle maintenance records can help improve your vehicle's resale value.
