Jatco JF506E and VW/Audi 09A neutral control valve controls the low clutch operating pressure in gears 1, 2 and 3. Because the valve is constantly oscillating from solenoid pressure, it commonly wears the valve bore.

Sonnax oversized neutral control valve kit 122892-13K allows you to restore the proper hydraulic control to the low clutch circuit.
