The Sonnax 96948-05K line pressure modulator plunger valve kit eliminates oil loss problems in Ford E4OD, 4R100, and AX4N transmissions. This high-performance valve kit features a 0.500-inch diameter design specifically engineered for extreme heavy-duty applications and performance builds from 1989-2004 Ford vehicles.

Key Features:

• Carbon steel sleeve manufactured to prevent excessive wear
• Hardened alloy steel valve for superior wear resistance
• O-ring helps prevent EPC oil loss
• Annular grooves center valve in sleeve and eliminate side loading
• Complete kit includes plunger valve, sleeve, and O-ring

This kit addresses severe wear of the line pressure modulator sleeve that can cause EPC oil leakage and plunger valve hang-up, resulting in harsh shifts or shifting issues. The precision-engineered components restore proper line pressure modulation and improve transmission performance and reliability.
