10L1000 / 10L60 (Gen 2) / 10L80 (Gen 2) / 10L90 (Gen 2) Oversized Feed Limit Low Valve Kit Fits GM 10-Speed Automatic Transmissions PROBLEM / CAUSE Severe side-load wear in the feed limit low valve bore reduces pressure to the default disable solenoid. This pressure loss can force the vehicle into default or power-loss mode and cause serious drivability issues. SOLUTION Reconditioning the bore and installing this oversized feed limit low valve kit restores proper hydraulic pressure, corrects valve function, and prevents future wear—without replacing the entire valve body. WHY THIS KIT MATTERS Overcome the GM 10-speed wheel lockup recall and get vehicles back on the road FAST with this drop-in solution. The feed limit low valve regulates line pressure to: Default disable solenoid Control valves Boost ball system for “A” and “B” clutch control Due to significant side-load forces, this valve commonly experiences severe wear, leading to: Pressure loss to the default disable solenoid Sudden downshift to 2nd gear Momentary wheel lockup at highway speeds Harsh shifting Diagnostic trouble code P0747 Failures have been documented as early as 30,000 miles, with many vehicles requiring service by 35,000 miles. GM RECALL BACKGROUND GM issued a national recall that installs updated software to monitor valve wear. When excessive wear is detected, the system triggers: Check Engine Light Reduced Propulsion message Vehicle limited to 5th gear (limp mode) The recall ultimately requires valve body replacement—a costly and time-consuming repair. THE SONNAX ADVANTAGE This patented oversized feed limit low valve kit (105740-59K) corrects bore wear and restores proper function without replacing the valve body. Key design benefits: Rerouted balance circuit through an internal passage Dramatically reduced side-load forces Upgraded materials to prevent future wear KEY FEATURES Corrects drivability issues related to the GM 10-Speed wheel lockup recall Patented valve and sleeve design overcomes bore wear Significantly reduces future side loading Hardcoat anodized aluminum valve resists premature wear Wear-resistant sleeve for long-term durability KIT CONTENTS Oversized Valve Sleeve Spring Retainer Drill (not shown) Rivet (not shown)
