Sonnax 96948-01K Line Pressure Modulator Plunger Valve Kit

The Sonnax 96948-01K line pressure modulator plunger valve kit addresses severe wear in the line pressure modulator sleeve that allows EPC (electronic pressure control) oil to leak past the valve, causing soft shifts, or causing the valve to stick and produce harsh shifts. This kit features a 0.427" diameter size bore and is designed for heavy-duty and high-performance applications in Ford E4OD, 4R100, and AX4N transmissions.

Key Features:

• Sleeve manufactured from carbon steel to prevent excessive wear
• Valve made from hardened alloy steel for better wear resistance
• O-ring helps prevent EPC oil loss
• Annular grooves center valve in sleeve and eliminate side loading
• Improves shift firmness

This kit resolves soft 1-2 or 2-3 shifts, intermittent harsh shifts, or poor line rise complaints often caused by ECU (electronic control unit) or accumulator pressure problems. The kit includes the valve, sleeve, and O-ring needed for installation.
