Mission: To deliver in-depth conversations about the 3.0 Duramax diesel platform, automotive technology, and the diesel truck community—bringing you behind-the-scenes insights, expert interviews, and technical discussions you won't find anywhere else. Mr. GregWrench is the podcast arm of Nelson Speed Co., hosted by Greg Nelson, a GM technician with over 20 years of dealership experience. Each episode dives deeper into the topics that matter to Duramax owners and diesel enthusiasts—from engine specifications and reliability concerns to product comparisons and industry trends. Whether you're commuting, wrenching in the garage, or just want to stay informed on the latest 3.0 Duramax developments, you'll get straightforward technical talk from someone who works on these trucks every day. No fluff, no hype—just real conversations about what works, what doesn't, and why it matters to your build. Part of the Nelson Speed Co. family alongside DemonWorks and Nelson Speed Co. content.
