I purchased my 2020 GMC Turbo Diesel and expected a premium, reliable truck — instead I’ve gotten nothing but frustration, expense, and stonewalling from both GMC Delray’s service department and GM Cus premium, reliable truck — instead I’ve gotten nothing but frustration, expense, and stonewalling from both GMC Delray’s service department and GM Customer Service. Owners across forums and Duramax community boards have been reporting 10-speed transmission valve body failures that lead to harsh shifting, torque converter shuddering, and even limp mode or lockup conditions. These issues aren’t rare anomalies — they’re well-documented complaints from GMC and Chevy owners with similar model years.  My truck began sputtering and shuddering under load, a classic symptom of torque converter and valve body problems that many others have also documented online. Despite my visits and clear diagnostic results showing failures directly tied to the transmission’s valve body and torque converter, GMC Delray refuses to classify the damage as a defect worthy of warranty coverage. They’ve told me the damage isn’t covered and wants me to pay for work that is clearly tied to a known failure trend. Other owners have experienced months at dealerships waiting on backordered valve body parts, or being offered only software updates that don’t fix the underlying failure.  To make matters worse, GM Customer Service has been dismissive, offering platitudes but no resolution, not standing behind their product, and forcing owners like me to fight for coverage that should be automatic under powertrain warranty. This has been an expensive, drawn-out nightmare. Based on my ordeal and the countless similar reports from real owners, I can no longer trust GMC or GM to honor their commitments. Avoid dealing with Delray’s “service” department unless you want endless excuses and zero accountability. (If you are experiencing the same concern I am there is a class action suit regarding the 10 speed transmission) Contact information at GM Service manager Ralph Nahmod Assistance service manager Dave Glickatein Master service consultant Casey Salman More
