4L30E Transmission Boost Valve Medium Ratio Sonnax 54200-01K AR25 AR35Medium Ratio, OE code 448In GM 4L30-E (AR25 and AR35) units the OE boost valves are made of steel, whereas the sleeves are made out of aluminum. Over time the valve wears against the sleeve and causes boost pressure leakage. The result is low line pressure during boost, with associated burnt clutches. Sonnax boost valve and sleeve kit 54200-01K restores pressure control to the boost circuit.Sleeve is made from wear-resistant aluminum and incorporates annular oil passages to distribute boost oil evenly to the valve and reduce side loadingValve is hardcoat anodized and includes oil grooves which allow the valve to ride on a film of oil, further reducing wearValve and sleeve are made from the same material to help reduce leakage due to thermal expansionNoteMedium boost ratio kit.
