Sonnax 76948-01 Main Pressure Regulator Valve for Ford AODE Transmissions - 4R70W

The Sonnax 76948-01 main pressure regulator valve restores normal line pressure operation in all ranges for Ford AODE and 4R70W automatic transmissions. This valve replaces 1995 and earlier 4-spool valves only and does not replace 3-spool valves.

Key Features:

• Hardcoat anodized aluminum construction combats premature wear
• Annular grooves help center valve in bore to reduce side-loading
• Direct replacement for worn OE pressure regulator valves
• Restores proper hydraulic pressure control

Vehicles with 4R70W and AODE transmissions often experience erratic line pressure, poor line rise, and throttle-sensitive buzz, which can result in harsh or soft shifts and band/clutch failure. Worn pressure regulator valve spools allowing pressure escape are a common problem in these units. This Sonnax replacement valve solves these issues by restoring proper valve function and sealing.

Note: If the bore is excessively worn, install Sonnax oversized pressure regulator and boost valve kit 76948-16K. The 1991-1995 and 1996-later pressure regulator valve designs are not interchangeable.
