Sonnax GM 4L30E Medium Ratio Boost Valve Kit OEM #48 AR25 AR35 4L30-E Automatic Transmission

Product Details


The OEM boost valves in 4L30-E units (also known as AR25 and AR35 in Europe) are made of steel, whereas the sleeve is aluminum. Over time the valve wears against the sleeve and causes boost pressure leakage. The result is low line pressure during boost, with associated burned clutches. The Sonnax kits 56200-01K, 54200-06K and 54200-12K restore pressure integrity to the boost circuit and incorporate several design details to reduce future wear.
