Subaru CVTF-II CVT Fluid 6 Quarts — Genuine OEM transmission fluid for Crosstrek Forester Outback Impreza

Genuine Subaru CVTF-II automatic transmission fluid (SOA427V1660) — six quarts of factory-specified green CVT fluid designed for select Subaru CVT-equipped models.

This six-quart package contains OEM Subaru CVTF-II (SOA427V1660) formulated specifically for Subaru continuously variable transmissions (CVT). The fluid is the original green CVT fluid Subaru specifies for many Crosstrek, Forester, Legacy, Outback and Impreza models. Use this when your service manual calls for CVTF-II to maintain the transmission’s designed performance, shift feel and hydraulic function.

Which Subaru models and years need this CVTF-II fluid?

This CVTF-II is intended for a range of Subaru vehicles equipped with factory CVTs. It fits specified model years and engine combinations; compatibility is determined by both model year and whether the vehicle is a hybrid, turbocharged or special edition (for example, Wilderness). Always check your owner’s manual or dealer parts table for the exact part number before purchase.

• 2013–2019 Crosstrek with CVT (non-hybrid)
• 2014–2016 Crosstrek with CVT hybrid
• 2014–2023 Forester 2.5 naturally aspirated with CVT (not for Wilderness edition)
• 2010–2019 Legacy 2.5 FB25 and 2010–2014 Legacy 3.6 with CVT
• 2010–2019 Outback 2.5 FB25 and 2010–2014 Outback 3.6 with CVT
• 2012–2023 Impreza 2.0 non-turbo with CVT

How do I know this is the right fluid and part number for my vehicle?

Confirm fitment by matching your vehicle’s model, engine code and year against the listed compatibility or your owner’s manual. The OEM part number SOA427V1660 is printed on Subaru packaging and parts listings; using the exact part number avoids cross-compatibility issues that can affect CVT operation.

• Look up SOA427V1660 in your Subaru parts catalog or dealer system
• Verify engine displacement and hybrid/turbo status for your model year
• Check that your vehicle’s service manual specifies CVTF-II or SOA427V1660

What are the practical benefits of using genuine Subaru CVTF-II?

Using factory-specified CVT fluid helps preserve the transmission’s intended shift characteristics and hydraulic control. Genuine CVTF-II is engineered to meet Subaru’s friction and viscosity targets for reliable belt/pulley operation and consistent temperature performance under normal driving conditions.

• OEM formulation tuned for Subaru CVT friction behavior
• Consistent viscosity for stable operation across temperatures
• Green color matching Subaru’s service identification

Can I install this fluid myself or should a shop do it?

Some experienced DIYers perform CVT fluid changes, but CVT service often requires special procedures, a proper fill level and, in some cases, dealer tools. If you’re not confident in following the exact refill and level-check steps, a certified mechanic or Subaru dealer will ensure correct fill and system checks.

• DIY possible with correct service manual and tools
• Dealer or qualified shop recommended for precise fill level and diagnostics
• Use six quarts to match the package volume for typical drain-and-fill services

Who is this for: this six-quart package of Subaru CVTF-II (SOA427V1660) is aimed at Subaru owners, independent mechanics and fleet technicians who need genuine OEM CVT fluid for compatible Crosstrek, Forester, Legacy, Outback and Impreza vehicles. Choose this if your vehicle’s service specification calls for CVTF-II and you want factory-original fluid for maintenance, repair or scheduled transmission service.
