How to Diagnose and Repair

If you own a 2018 Chevrolet Silverado, you may have experienced transmission issues such as grinding, slipping, and erratic shifting.

When diagnosing transmission issues, it is important to pay close attention to the symptoms. If you notice grinding or slipping, the problem may be caused by a worn-out clutch or worn-out gear teeth. If you experience erratic shifting, the issue may be due to an electrical fault or a dirty filter.

Once you have determined the cause of the issue, you can begin the repair process. If the issue is due to a worn-out clutch or gear teeth, you will need to replace the transmission components.
