A flexplate is an important part of your automatic transmission. The flexplate in your GMC Sierra 3500 HD helps to adjust small misalignments between the engine and transmission. The flexplate provides protection to the other components because it will not crack. At StockWiseAuto.com, you have a wide variety of flexplates to choose from.


Some of the indicators that you have a problem with your flexplate include whining noises from the starter, clunking and grinding while in neutral and vibrations when your speed increases. If your GMC Sierra 3500 HD transmission system has a problem with its flexplate, StockWiseAuto.com offers a 30-day money-back guarantee on all products.
