Model notes: A four-piece solenoid kit designed for Subaru CVT-equipped models, including Crosstrek, Forester, Outback, Legacy, and Impreza. Provides pressure control and lock-up operation replacements to restore smooth CVT performance and prevent shifting irregularities.

Key considerations: The kit targets models with TR580/TR690 and related OE references. Ensure compatibility with your CVT transmission and confirm OE part numbers before ordering to avoid mismatches.

Buying Guide: Torque Converter Solenoids

  • Compatibility and fitment: Solenoids must match the specific transmission code, model year, and engine configuration. Use the OE part number or vehicle-specific compatibility notes to confirm fitment before purchase.
  • Function and control: Distinguish between torque converter clutch (TCC) solenoids and lock-up solenoids. TCC solenoids control the clutch apply/release, while lock-up solenoids manage the torque converter’s lock-up state for fuel economy and smooth operation.
  • Durability and materials: Look for corrosion-resistant housings, robust internal components, and high-temperature tolerance to withstand ATF exposure and electrical loads.
  • Installation considerations: Some solenoids are direct replacements, while others require more extensive valve-body work. If unsure, consult a professional mechanic to evaluate wiring harness compatibility and calibration needs.
  • Diagnostics and symptoms: Faulty solenoids can cause harsh or slipping shifts, trans codes (like P2763), or poor fuel economy. Replacing the faulty unit can restore shifting feel and transmission behavior without replacing the entire valve body.
  • Cost versus replacement scope: Replacing just the solenoid can be cost-effective compared to a full valve-body replacement. However, if multiple transmission components are worn, comprehensive service may be warranted.
  • Warranty and supplier reliability: Choose parts with a clear warranty and from reputable brands to ensure consistent performance and support if issues arise.
  • Cross-brand compatibility: Some kits cover multiple models or transmission families (for example 62TE/41TE/42RLE). Confirm the exact transmission code to avoid incompatibility.

When selecting a torque converter control solenoid, prioritize precise fitment, durable construction, and compatibility with your vehicle’s transmission family. The five options highlighted here provide a mix of direct replacements and OE-style solenoids across domestic and imports, offering viable paths to restore smooth shifting and optimize transmission performance.
