Tool Kit for 74846-06K

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. Refer to the following chart for appropriate part numbers and applications.
