The continuous oscillation of the pressure regulator valve in Aisin Seiki AS69RC and AS66RC units wears the valve as well as the bore. If severe wear occurs the pressure regulator valve won't stroke properly to regulate line pressure. This can result in high as well as low line pressure, which can lead to various shift complaints and burnt clutches. Sonnax oversized pressure regulator valve kit 122740-07K has significant improvements over the OE design to prevent future wear. With installation of this kit, the valve body bore can be refurbished and hydraulic integrity restored.

Hardcoat anodized aluminum valve combats premature wear
Added spring pocket increases contact area and reduces wear
Oversized valve maintains OE pressures
