Product Details

The Sonnax 4R100-LB1 line pressure boost valve kit is designed to address low line pressure issues in Ford 4R100 automatic transmissions. This kit helps restore proper hydraulic pressure in worn transmission units, improving shift quality and preventing slippage under load.

Key Features:

  • Restores proper line pressure in high-mileage 4R100 transmissions
  • Improves shift firmness and reduces clutch slippage
  • Precision-machined components for reliable performance
  • Direct replacement for worn OE pressure regulator components
  • Designed for professional transmission rebuild applications

This line pressure valve kit is an essential upgrade during 4R100 transmission rebuilds, particularly for units used in towing or high-performance applications. The kit includes precision valve components that restore hydraulic integrity to the transmission's pressure control system.
