Sonnax 144740A-01 Oversized Solenoid Pressure Regulator Valve for Ford 6F35 Transmission

The Sonnax 144740A-01 is an oversized solenoid pressure regulator valve designed to restore proper hydraulic control in Ford 6F35 Generation 1 and 2 transmissions. This precision-engineered valve addresses common transmission problems caused by wear in the solenoid pressure regulator bore, which can lead to low clutch pressure and result in transmission slipping, harsh shifts, and eventual loss of gears.

Key Features:

• Oversized design compensates for bore wear and restores proper valve-to-bore clearance
• Hardcoat anodized aluminum construction resists premature wear and extends service life
• Engineered to perform to OE specifications while providing superior durability
• Drop-in installation using Sonnax reaming tool kit 144740-TL (sold separately)
• Restores regulated pressure supply to shift solenoids for proper clutch operation

Application:

• Ford 6F35 automatic transmission (Generation 1 and 2, 2009-2018)
• Common in Ford Fusion, Escape, Taurus, Transit Connect, and Lincoln MKC vehicles

Symptoms Corrected:

• Transmission slipping or harsh shifting
• Low clutch oil pressure
• Flare shifts between gears
• Loss of 4th, 5th, or 6th gear function

The solenoid pressure regulator valve plays a critical role in providing regulated hydraulic pressure to shift solenoids throughout the transmission. When bore wear occurs, pressure control is compromised, leading to erratic shift quality and potential transmission failure. The Sonnax oversized valve solution allows technicians to machine the worn bore to a precise oversize dimension and install this upgraded valve for a long-lasting repair.

Note: Installation requires Sonnax reaming tool kit 144740-TL to properly prepare the valve body bore. This precision valve is a professional-grade repair component designed for use by qualified transmission technicians.
