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)

We’re sorry to hear how frustrating this experience has been for you. We do want to clarify that our team has advocated on your behalf. We were able to secure substantial help on your recent visits, even though your warranty had expired. Most recently, on 1/30/2026, we again obtained 60% coverage toward the transmission repair to reduce your cost as much as possible. We recognize that your concerns relate to GM’s broader manufacturer policies, and we’re sorry that this has added to your frustration. We remain committed to helping you in any way we can and are here to assist with any next steps.

I understand you guys offered 60% for a faulty part that GMC caused. My question to you is show me all your extended warranties GM provided your dealer regarding transmissions issues. I know how you guys tweaked the numbers, especially in the warranty and service department to gain profit for the dealership. If you can be transparent, I would accept your offer. I’ll be waiting for your response.
The service staff were friendly,knowledgeable and
efficient in their handling of the job I will be back again.
