Transmission Torque Converter Clutch Lock-Up Solenoid 3.0-3.5ohm Compatible with Subaru Lineartronic CVT TR580 TR690 Replace 926-408 31825AA050 31825AA051 31825AA052

Restore Smooth CVT Drive with a Precise OEM-Fit SolutionYour Subaru’s drivability depends on accurate control of the torque converter clutch. This replacement Torque Converter Clutch (TCC) Lock-Up Solenoid is engineered for Subaru Lineartronic CVT systems—models TR580 and TR690—to restore proper lock-up timing and hydraulic balance. Calibrated resistance of 3.0–3.5Ω matches factory spec.What it fixes: A weak or sticking solenoid often causes shudder, slipping, delayed acceleration, high RPM cruising, or overheating. Replacing the lock-up solenoid valve re-establishes commanded clutch pressure so your CVT can hold torque at speed and disengage smoothly at stops—improving fuel efficiency and extending transmission life.Exact Fit & OE Numbers: Direct replacement for OE# 31825AA050, 31825AA051, 31825AA052.Precision Hydraulic Control: Tight-tolerance spool, consistent coil impedance, and stable magnetic force deliver repeatable pressure modulation under heat and load.Durable Construction:Corrosion-resistant finish, and high-temperature seals designed for continuous CVT duty.Efficient Repair: Rapid install for pros or experienced DIYers—an economical fix versus major transmission work.Vehicle Compatibility (verify trim & CVT): Outback, Forester, Legacy, Crosstrek, Impreza equipped with TR580/TR690 Lineartronic CVT.Why this matters: At cruising speeds the torque converter clutch locks to eliminate slip. If the solenoid can’t build the commanded pressure, the clutch dithers, creating heat and wear. This calibrated TCC lock-up solenoid restores the control window the TCM expects, stabilizing RPM, reducing heat, and returning that quiet, confident Subaru feel.Note: Compare resistance (3.0–3.5Ω), connector, and OE part number to your original before installation. Professional diagnosis is recommended when multiple CVT DTCs are present.

• Perfect Compatibility – Designed for Subaru Lineartronic CVT transmissions TR580 & TR690, compatible with select Subaru models including Subaru Crosstrek Forester Legacy Outback Impreza. This torque converter clutch lock-up solenoid is a direct fit replacement for OE 31825AA050, 31825AA051, 31825AA052.
• Restores Smooth CVT Operation – A failing lock-up solenoid valve often causes shudder, rough shifting, delayed acceleration, or overheating. Replacing it restores proper torque converter engagement, ensuring stable performance in transmission torque converter lock-up systems delivering smoother driving and longer transmission life.
• Durable Construction – Manufactured with, high-temperature resistant seals, and corrosion-proof housing, this part withstands the extreme heat and pressure of Subaru CVT systems for long-lasting durability.
• Precision Hydraulic Control – Built with OEM-grade components, this solenoid regulates fluid pressure with high accuracy, ensuring the torque converter clutch engages and releases at the correct time, preventing unnecessary wear and improving fuel efficiency.
• Fast & Cost-Effective Repair – Designed as a direct replacement for the original valve body solenoid, No need to replace the entire valve body—simply install based on resistance (3.0-3.5Ω), helping avoid costly transmission replacement while restoring original Subaru driving performance.
