Note:

Oversized Pressure Regulator ValvePart No. 74846-06K Tooling: 74846-TL6 The spring seat on the valve has been modified to compensate for the oversized valve. Valve provides higher line pressure at idle. Salvages expensive, hard to find valve bodies Note: It is highly recommended that the pressure modifier valve bore be checked for wear on the F4A-EL, FA4A-EL & F4E-III units as well. Wear at this bore can result in erratic shift quality and high/low line and EPC pressures. Sonnax offers an oversized pressure modifier valve, 74846-07K, which can be used to refurbish bore wear at this location. See instructions for appropriate part numbers and applications.
