Sonnax 76948-09 Main Pressure Regulator Valve for Ford AODE Transmissions - 4R70W 4R75W

The Sonnax 76948-09 main pressure regulator valve restores normal line pressure operation in all ranges for Ford AODE, 4R70W, 4R70E, 4R75W, and 4R75E automatic transmissions from 1996 and later model years.

Common Problems This Part Solves:

• Low line pressure or throttle sensitive buzz, especially when hot, often caused by a worn main regulator valve
• Wear on the boost spool diameter that allows EPC (electronic pressure control) oil to leak to exhaust, resulting in poor line rise
• Worn pressure regulator valve spools allowing pressure escape

Important Compatibility Notes:

• Designed specifically for 1996 and later transmission models
• 1991-1995 PR valve and 1996-later PR valve designs are not interchangeable; for 1991-1995 PR valve, see part number 76948-01
• If bore is excessively worn, install Sonnax oversized pressure regulator and boost valve kit 76948-17K

This direct replacement valve eliminates pressure regulation issues and restores proper hydraulic function to your transmission's main pressure control system.
