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 offers a oversized pressure regulator valve kit 122892-03K to restore hydraulic pressure control in Jatco JF506E and Volkswagen AG5/09A 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; and Nissan ZY units.
