FUSCH Torque Converter Lock-Up Solenoid for Subaru TR580/TR690 (12–13Ω) – Direct-Fit TCC Replace#31825AA050

FUSCH's Torque Converter Lock-Up Solenoid (12–13Ω) is a direct-fit replacement TCC solenoid engineered to restore torque-converter lock-up control in Subaru TR580/TR690 transmissions.

If your Subaru is throwing transmission codes related to the torque converter clutch—such as P2764, P2763, or P2762—or if you’re experiencing poor shift quality or torque-converter slipping, this FUSCH TCC solenoid is built to replace the original unit (including OE references like 31825AA050 and related part numbers). It’s designed specifically for 12–13 ohm circuits and fits a range of Subaru models with TR580 or TR690 transmissions, including Legacy, Outback, Impreza, Forester and Crosstrek model years listed below. The solenoid arrives as a single unit, ready for straightforward installation when you confirm the required resistance match.

Which Subaru models and transmissions does this solenoid fit?

This FUSCH solenoid is formulated for Subaru vehicles that use TR580 or TR690 transmissions. Confirm fitment against your year and transmission type before ordering.

• Subaru Legacy: 2010–2017
• Subaru Outback: 2010–2017
• Subaru Impreza: 2012–2016
• Subaru Forester: 2014–2017
• Subaru Crosstrek: 2013–2014

How do I know this is the right resistance (12–13Ω) for my car?

Always verify the solenoid coil resistance against the specification for your vehicle or the code you retrieved. This unit is specified at 12–13 ohms and should replace solenoids that use that resistance range.

• Measure existing solenoid coil with a multimeter—expect about 12–13Ω.
• Match the ohm value rather than wire color to ensure correct operation.
• If codes P2764, P2763, or P2762 appear, check resistance as part of diagnosis.

What original part numbers does this solenoid replace?

FUSCH designed this TCC solenoid to be compatible with a variety of OEM and aftermarket references, making it a suitable replacement for several legacy part numbers commonly used on Subaru transmissions.

• Replaces: 31825AA050, 31825AA051, 31825AA052
• Also compatible with: 31706AA030 / 031 / 032 / 033 and 31706AA140 / 141 / 142
• Cross-reference: 926-408 and related transmission solenoid codes

How difficult is installation and what’s included?

Replacement is straightforward for anyone comfortable working under the vehicle or with basic transmission access. This product ships as a single TCC solenoid and should be installed following resistance verification and standard safety procedures.

• Package contains: 1 x transmission torque converter clutch solenoid (TCC solenoid)
• Install using vehicle service manual steps and torque specs where applicable.
• Confirm electrical connector and harness fit, and clear codes after replacement.

Who is this for: This FUSCH torque converter lock-up solenoid is aimed at DIY mechanics, independent repair shops, and Subaru owners who need a 12–13Ω replacement TCC solenoid for TR580 or TR690 automatic transmissions. It’s particularly useful if diagnostic trouble codes point to the lock-up circuit or if the original solenoid shows out-of-spec resistance. Always confirm compatibility with your vehicle year and transmission type before purchase.
