Sonnax 105740-58K Feed Limit High Valve Kit GM 10-Speed Transmission Zip Valve Drop-In Repair

The Sonnax 105740-58K Feed Limit High Valve Kit is a drop-in repair solution engineered to correct circuit pressures and restore proper valve function in GM 10-speed automatic transmissions. The OE feed limit high valve bore is highly susceptible to premature wear, and excessive bore wear can allow internal leakage — leading to no-shift conditions, burnt clutches, and premature clutch failure.

This kit resolves those issues by restoring correct circuit pressures and valve operation without the need to replace the entire valve body. Designed as a Sonnax Zip Valve™ drop-in repair, installation is fast and straightforward with no special machining required, making it ideal for valve body service or as a preventative upgrade during a full transmission rebuild.

Key Features:

• Hardcoat anodized aluminum valve combats premature wear and extends service life
• Highly wear-resistant valve sleeve increases durability over OE components
• Calibrated replacement spring maintains OE functions and pressures
• Drop-in Zip Valve™ design installs quickly with no special tools or machining required
• Restores reliable clutch apply, consistent shifting, and extended transmission life
• Recommended as a preventative replacement even if no transmission problems are currently present

The Sonnax 105740-58K is compatible with GM 10L1000, Gen. 2 10L60, 10L80, and 10L90 automatic transmissions. Sold as a complete kit including valve, sleeve, and spring.
