Transmissions showing symptoms of soft shifts from 1-2 or 2-3, periodic harsh shifts, or low line rise may be able to correct the problems with one of these Sonnax Line Pressure Modulator Plunger Valve kits. When sleeves become worn, electronic pressure control (EPC) oil can leak past the valve to cause the soft shifts; valves will also stick or hang up through wear, leading to the rough shift issue. Sonnax kits include a replacement modulator sleeve made from carbon steel to combat extreme wear, along with a durable plunger valve crafted from hardened alloy steel. The O-ring helps to prevent EPC oil loss. Sonnax Line Pressure Modulator Plunger Valve kits are produced for fitment on a variety of transmissions, including 6 and small 8-cylinder applications. Select the kit that's tailored to your vehicle.

Sonnax throttle valve plunger kits address the poor line rise or no detent downshifts that can be common complaints in vehicles with a stock overdrive transmission. The steel plunger continuously reciprocates within the aluminum sleeve, wearing out the sleeve. This wear (plus the weak OE spring) allows throttle valve feed oil to leak past the plunger and exhaust, resulting in the aforementioned issues that can lead to 3-4 clutch failure. Sonnax throttle valve plunger kits include an improved throttle valve spring designed to properly maintain higher line pressure and improved throttle valve performance. Order the kit recommended for your transmission application. Features and items: * High-quality aluminum sleeve prevents wear * Tight-tolerance sleeve and plunger restore hydraulic integrity * Eliminates the part throttle sleeve orifice * Spring * Sleeve * Plunger
