Reverse servo spacer 4L80E

Reverse servo spacer 4L80E Short Spacer Belleville Spring Washer Flat Washer E-clip Increased contact area reduces pressure between apply pin and piston by 60%. Added Belleville spring washer reduces shock on piston. No machining necessary, drop-in components. Maximum durability for minimal cost. Symptoms: Broken Low/Reverse servo piston No Reverse Cause: Poor reverse servo design and high pressures in reverse combine to cause reverse servo breakage. Correction: Install the Sonnax kit to increase piston to spacer contact area, reduce stress on the underside of the piston and add a Belleville spring washer between piston and apply pin.
