TOOLING REQUIRED

Vehicles equipped with Aisin AW 55-50SN and 55-51SN transmissions may suffer from delayed Forward engagement and require increased throttle for engagement. These problems are caused by bore wear at the neutral relay valve, resulting in loss of clutch engagement pressure. This can be fixed with the Sonnax oversized neutral relay valve kit 59947-35K. The Sonnax valve kit restores clutch pressure, which will eliminate delayed engagement and the need for increased throttle.
- Hardcoat anodized aluminum valve combats premature wear
- Tighter fit to bore than OE for better sealing
- F-59947-TL34 tool kit can be used for both 59947-34K and 59947-35K oversized valve kits
