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.

“I purchased my 2020 GMC Turbo Diesel expecting a dependable, high-performing truck. After experiencing issues with the transmission — including shuddering under load — I initially felt frustrated, especially after seeing similar concerns reported by other Duramax owners regarding valve body and torque converter performance. However, after working through the situation with GMC Delray’s service department, I can say they were willing to step in and work with me toward a resolution. While the repair was not fully covered under warranty and I did have some out-of-pocket costs, the team made an effort to address the issue and move the process forward. This was not a quick or perfect experience, but I do appreciate that the dealership ultimately took the time to evaluate the problem and help find a workable solution. If you’re dealing with a similar concern, it’s worth staying engaged with the service team and advocating for your case, as they are willing to work with you.”
