Dorman 926-408 Torque Converter Lock-Up Solenoid
This solenoid is designed as an OE-compatible replacement for Subaru models. It focuses on replacing only the solenoid rather than the entire valve body assembly, delivering meaningful cost savings while maintaining proper fit and function. When installed correctly, it can help address the P2763 fault code by restoring the lock-up function of the torque converter. The part is engineered to precise specifications to ensure compatibility with select Subaru vehicles, aligning with factory performance expectations. For technicians and DIYers, the straightforward swap reduces downtime and complexity compared to a full valve body replacement.
Key considerations include verifying the vehicle’s year, model, and OE numbers to ensure a seamless fit. The solenoid’s electrical resistance and connector compatibility should mirror original hardware to prevent misdiagnosis. While this part aims to restore proper lock-up behavior, users should inspect surrounding valve body seals and transmission fluid condition if symptoms persist after replacement.
Applications: Subaru Legacy/Outback/Impreza lines with TR580 or TR690 CVT arrangements. It’s a practical choice for customers seeking a targeted fix that minimizes labor and material costs while delivering reliable engagement of the torque converter clutch.
ZGTools 926-408 Torque Converter Lock-Up Solenoid
This unit is tailored for Subaru TR580 and TR690 CVT transmissions and is compatible with multiple Subaru models including Legacy, Outback, Impreza, Forester, and Crosstrek from various model years. It replaces OE parts 31825AA050/051/052 and similar numbers, serving as a fitting stand-in for a TR580 valve body solenoid replacement or TR690 solenoid swap. A standout feature is the specified 12–13 ohms resistance, which supports stable lock-up operation and helps clear related check engine codes such as P2762, P2763, and P2764. The design emphasizes direct replacement compatibility to avoid valve body removal.
Installation benefits from a straightforward swap: match the resistance value, remove the old solenoid, and install the new part without extra disassembly. This makes it attractive to both mechanics and motivated enthusiasts. If symptoms include slippage under highway load or erratic transmission behavior tied to the lock-up system, this solenoid provides a direct path to restoration when paired with proper transmission fluid maintenance.
Compatibility notes should be reviewed against your specific VIN and transmission configuration. While it mirrors OEM specs, verifying connector type and mounting orientation helps prevent misalignment or electrical fit issues during replacement.
FUSCH Torque Converter Lock-Up Solenoid
FUSCH offers a multi-OE-part replacement solenoid designed for Subaru Outback, Legacy, Impreza, Forester, and Crosstrek models featuring TR580/TR690 transmissions. The listing highlights compatibility with several OEM part numbers in the 31825AA050, 31825AA051, 31825AA052 family, along with 31706AA030 series, forming a broad compatibility umbrella. The 12–13 ohm resistance range is noted as part of the design, aligning with typical lock-up solenoids for stable clutch engagement. This makes it suitable for users who need a single part compatible with several factory configurations, simplifying inventory for repair shops or DIY projects.
Customers should confirm model year and engine specifications to ensure the TR580/TR690 fitment. The product is positioned as a direct replacement for the original valve body solenoid, reducing the threat of misfit issues and eliminating the need to replace the entire valve body in many cases. Proper torque converter performance hinges on correct electrical resistance and robust electrical connections, so checking those details is advised during installation.
Overall, this option provides a versatile path for correcting lock-up problems with CVTs in multiple Subaru models while avoiding more extensive transmission work.
LDCRE Lock-Up Solenoid
LDCRE’s lock-up solenoid targets Subaru Crosstrek, Forester, Legacy, and Outback with CVT TR580/TR690 configurations.

The listing emphasizes a straightforward replacement process with a single solenoid package, which is ideal for quick repairs or stocking needs for shops handling multiple Subaru CVT units. It may be used as a practical option when the goal is to restore lock-up function without swapping the entire valve body assembly.
Key considerations include verifying part numbers and ensuring model-year compatibility. While price is a favorable driver for choosing this option, confirming resistance and connector compatibility is essential to prevent misalignment or ineffective repair. The solenoid’s reliability should be evaluated alongside overall transmission condition, including fluid quality and valve body cleanliness, to ensure lasting performance after installation.
Kessocco CVT Lock-Up Solenoid

Buying Guide: Key Considerations When Selecting a Torque Converter Lock-Up Solenoid
- Model-year and transmission compatibility: Confirm TR580/TR690 fitment and verify the OE part numbers listed for your vehicle.
- Electrical resistance: Many lock-up solenoids specify a resistance range (commonly around 12–13 ohms or similar). Match the specified range to avoid control issues.
- OEM vs aftermarket: OE-match parts offer direct compatibility; aftermarket options can save money but may require careful verification of wiring, connectors, and fit.
- Installation scope: Some solenoids are a direct replacement; others may require valve body access. Assess whether DIY replacement is feasible or if professional service is advisable.
- Symptoms indicating replacement: Check engine light codes such as P2762, P2763, and P2764, along with symptoms like slipping, hard shifts, or erratic lock-up engagement.
- Quality and durability: Look for parts with robust construction, appropriate materials for engine heat, and reputable brand support or warranty.
- Vehicle maintenance context: A solenoid replacement is most effective when paired with good transmission fluid health and a clean valve body environment.
- Return policy and compatibility guarantees: When ordering multiple parts for repairs, ensure the seller offers reliable returns if the part does not fit.
In selecting a torque converter lock-up solenoid for Subaru CVTs, prioritize accurate OE-number matching and resistance specifications. A well-chosen solenoid can restore lock-up reliability, improve fuel economy, and stabilize transmission behavior without the need for full valve body replacement. Consider your repair goals, budget, and the level of labor you’re prepared to invest to choose the best option for your vehicle.
