Sonnax highlights its oversized secondary pressure regulator valve kits for Aisin Seiki AS66RC and AS69RC transmissions. The company says reconditioning the bore and installing these kits can help users restore proper hydraulic integrity of the SLT circuit in these transmission models.
These kits include a hardcoat anodized aluminum valve that the company says combats premature wear, and a wear-resistant boost valve sleeve that increases the part’s life according to Sonnax.
