Sonnax 105740-54K Feed Limit Low Valve Kit for GM 10-Speed Transmissions

The Sonnax 105740-54K is a patented, drop-in feed limit low valve kit that overcomes bore wear, restoring proper valve function immediately without the need or expense of replacing the entire valve body. This kit is designed for GM 10L1000, 10L60 (Gen. 2), 10L80 (Gen. 2), and 10L90 (Gen. 2) transmissions.

Addresses Critical Transmission Issues:

The feed limit low valve is subject to significant side-load force, resulting in severe wear and pressure loss to the default disable solenoid and connected control valves. This pressure loss can put the vehicle into default mode at high speeds, resulting in momentary wheel lockup, sudden downshift to 2nd Gear, harsh shifts or a P0747 code. The feed limit low valve can wear out in as little as 30,000 miles, with many vehicles requiring service by 35,000 miles.

Key Features:

• The valve reroutes the balance circuit through an internal passage, significantly reducing the side-load force, while upgraded materials prevent future wear
• Patented valve and sleeve combination overcomes bore wear and significantly reduces future side loading of the valve
• Hardcoat anodized aluminum valve and wear-resistant sleeve combat premature wear
• Drop-in Zip Valve™ parts install quickly and easily
• Overcomes drivability issues related to GM Safety Recall N242480630 for the GM 10-speed wheel lockup condition

The OE feed limit low valves are at high risk for premature wear and failure. Replace the valve in every build even if there are no transmission problems and the valves pass a vacuum test.
