The 2010 Scion xB requires different transmission fluids depending on which transmission it has: automatic transmissions use Toyota Type T-IV ATF, while manual transmissions use SAE 75W-90 GL-4 gear oil. This article breaks down those requirements and how to apply them correctly.
In this model year, Scion offered both an automatic and a manual transmission. The fluid specification is tied to the type of transmission installed in your vehicle, so it’s important to identify which one you have before servicing.
Fluid specifications by transmission type
Below are the fluids associated with each transmission option found in the 2010 Scion xB. If your car has market-specific variants or has undergone a transmission swap, verify with the owner’s manual or a Scion/T Toyota dealer.
Automatic transmission fluid (4-speed)
For the automatic transmission in the 2010 xB, use Toyota Type T-IV ATF. The fluid should meet the T-IV specification to ensure proper shifting and protection.
- Toyota Type T-IV ATF (factory-specified for this transmission)
Using the correct ATF is essential for reliable operation and to preserve warranty coverage. If the vehicle initially came with a different specification, consult the service manual or dealer guidance before mixing fluids.
Manual transmission fluid
For the manual transmission, use SAE 75W-90 GL-4 gear oil. This grade and specification are commonly recommended for Toyota-based manuals of this era to protect the synchronizers and gears.
- SAE 75W-90 GL-4 gear oil (do not use GL-5, which can affect synchronizers in some transmissions)
Always confirm the exact grade and spec for your vehicle in the owner’s manual or via a dealer, especially if the car has been serviced outside standard market specifications.
Maintenance tips and considerations
Regularly checking transmission fluid level and quality helps prevent shifting issues. For automatics, use the dipstick or service window to confirm the level, and replace the ATF according to your maintenance schedule. For manuals, check for leaks, and change the gear oil at intervals recommended by Toyota or your service center.
Summary
To answer the question succinctly: an automatic 2010 Scion xB uses Toyota Type T-IV ATF, and a manual xB uses SAE 75W-90 GL-4 gear oil. Always verify the exact specification in your owner’s manual or with a dealership, as market variations or previous drivetrain changes can affect the correct fluid type.
What type of transmission fluid does a 2010 Scion XB take?
Dexron VI Automatic Transmission Fluid
FRAM – FRAM Full Synthetic Dexron VI Automatic Transmission Fluid, 1 Quart (Part No. F426)
Can low transmission fluid cause stuttering?
If shuddering occurs primarily between 30-45 mph, this suggests torque converter problems related to low fluid levels. This specific speed range often reveals transmission issues that might not be noticeable at other speeds.
Can I use ATF instead of Dexron?
For example, ATF+4 is compatible with vehicles requiring ATF+2, and DEXRON VI can be used in place of the original DEXRON. However, there are some low-viscosity and high-performance exceptions to this backward compatibility rule, which we will cover a bit later.
What transmission does a 2010 Scion XB have?
Automatic Transmission (2.4L, 4CYL, 2WD, Automatic, 4SPD)
