Sonnax 76948-16K Oversized Pressure Regulator and Boost Valve Kit

The Sonnax 76948-16K oversized pressure regulator and boost valve kit is designed for Ford AODE, 4R70W, 4R70E, 4R75W, and 4R75E transmissions ('95 and earlier models). This kit provides a solution for excessively worn valve body bores that cause erratic line pressure, poor line rise, and throttle-sensitive buzz.

Key Features:

• Oversized design fits worn valve body bores that standard valves cannot repair
• Hardcoat anodized aluminum construction combats premature wear
• Annular grooves help center valve in bore to reduce side-loading
• Restores normal line pressure operation in all ranges
• Addresses harsh or soft shifts, band/clutch failure, and driveability concerns

Application Notes:

• Fits '95 and earlier transmissions only
• Requires reaming with Sonnax tool kit F-76948-TL and VB-FIX fixture
• Use Sonnax bore sizing tool 76948-BST for proper installation
• '91-'95 and '96-later pressure regulator valve designs are not interchangeable

This oversized valve kit is the recommended solution when standard pressure regulator valve 76948-01 cannot adequately repair worn bores.
