OE replacement bushings can allow critical line pressure to exhaust because of poor fit. This line pressure feeds the E2 clutch and provides critical lube. When the bushing is worn or incorrectly toleranced, it will result in poor or erratic 2nd gear shifts, burned clutches and loss of lube. The Sonnax replacement bushing 120002 is designed to provide the proper clearance for this application.
The Sonnax bushing is designed to maintain minimal clearance between the bore and the mating shaft to greatly enhance the life of the bushing. As a result, there may be situations where the mating shaft and bushing don't fit due to some small interference. In this instance you may carefully polish the bushing bore with fine emery cloth or a fine abrasive hand pad until the shaft fits in the bushing.
