Upgrade your transmission's performance with the Sonnax Boost Valve Kit, designed for 6L45, 6L50, 6L80, and 6L90 models. This kit includes high-quality components to address common transmission issues and ensure smooth and reliable operation.
Symptoms:
- Low line rise in Drive
- Soft shifts
- Burnt clutches
Cause:
Wear of the boost valve sleeve allows EPC fluid pressure to escape to exhaust.
Correction:
The Sonnax drop-in boost valve kit features upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control. The sleeve has a slightly larger EPC feed orifice for quicker throttle response. A new pressure regulator valve outer spring is also included to replace weakened original springs, providing a modest 5 psi increase across the pressure curve.
Features:
- Boost sleeve is manufactured from highly wear-resistant billet aluminum to prevent wear
- Larger feed orifice provides quicker throttle response
- Replacement spring provides a modest 5 psi line pressure increase
- Drop-in Zip Valve™ parts install quickly and easily
Kit Contents:
Vehicles with the specified GM transmissions may experience insufficient line rise in drive ranges, soft shifts, and/or burnt clutches. These issues are often caused by continuous oscillation of the boost valve within the boost sleeve, creating excessive wear and a path for EPC fluid pressure to leak to exhaust. The Sonnax Boost Valve Kit (part no. 104520-12K) includes upgraded materials and minimal clearances to prevent wear and restore proper hydraulic control.
