Sonnax Main Pressure Regulator Valve for Ford AODE Transmissions

The Sonnax Main Pressure Regulator Valve (pressure regulator valve) is a drop-in replacement for the worn factory valve in Ford AODE-family automatic transmissions, including the 4R70W, 4R70E, 4R75W and 4R75E. It helps restore stable line pressure in the valve body.

Worn pressure regulator valve spools let pressure escape. This is a common problem in these units. It can cause erratic line pressure, poor line rise and throttle-sensitive buzz. These problems can lead to harsh or soft shifts, and to premature band and clutch failure. The Sonnax valve restores normal line pressure operation in all ranges.

Key Features:

• Hardcoat anodized aluminum construction resists premature wear
• Annular grooves help center the valve in the bore and reduce side-loading
• Zip Valve-style drop-in design for straightforward installation during a valve body rebuild
• Addresses poor shift quality, soft shifts, low line rise, erratic buzz and low Reverse boost
• Made in the USA by Sonnax, a well-known name in transmission rebuilding and performance parts

The factory valve designs for earlier and later production years are not interchangeable. Choose the variant that matches your transmission's valve design. This is a good choice for transmission rebuilders and owners who want to fix pressure regulation problems at the source.
