Constant movement of the pressure regulator valve wears the valve body bore. Bore/valve wear causes erratic line pressure, resulting in delayed engagements, loss of lockup and high or low line pressure, depending on the area and extent of wear. Sonnax oversized pressure regulator valve kit 122892-03K restores hydraulic pressure control in Jatco/Nissan JF506E and VW/Audi 09A units.

These valve and tool kits also service Jatco FP series; Ford JF506E, FPH; Jaguar JF506E, FPD; Mazda JA5A-EL FPF1/FPF2; Rover JF506E, FPO; Nissan ZY units; and VW/Audi AG5 units.
