The ‘Allison’ 10-Speed Scam? Inside GM’s Silverado/Sierra HD Transmission Failures, Valve-Body Chaos & the Branding Divorce

Did GM really put an Allison transmission in the 2020–2025 Chevy Silverado 2500HD/3500HD and GMC Sierra HD—or did they just rent the name? In this episode, we unpack the controversy around the Allison-branded 10-speed (10L1000): why longtime truck buyers believed they were getting bulletproof Duramax-era reliability, and why so many owners now report harsh shifting, limp mode, valve body failures, and months-long parts backorders.We break down how brand licensing works in the auto industry, what the “Allison” badge actually signals (and what it doesn’t), and why this saga has become a case study in marketing vs. mechanical reality. Plus: how the situation escalated into a full-on reputation problem—so big that GM and Allison are reportedly ending the partnership and even removing Allison badging from unsold trucks after the agreement expires.If you tow, haul, run a small business, or you’re shopping used HD trucks, this is the episode you need before you sign anything.▶ JOIN the Expedition Money Community for FREE!Use the code below at the following link ($1,200 value): https://expedition.money/subscription...Free Access Code: FREEXMYEAR▶ Get a copy of my book, AMAZING MONEY STORIES here! https://geni.us/R7efGET INSIDER COLLEGE PLANNING INFORMATION:▶ Mastering FAFSA Strategies to Maximize Your Financial Aid Course: https://www.udemy.com/course/collegef...----------GET MY BOOKS!▶ How I Make A Six-Figure Income On YouTube Book: https://geni.us/UZ2bnyd▶ How To Get Out Of Debt Fast Book: https://geni.us/HeWdQi1▶ Rethink Money Book: https://geni.us/O1tcs▶ Amazing Money Stories Book: https://geni.us/R7ef▶ Just The Essential Disney Hacks Book: https://geni.us/cYZO3T0▶ Living The Dream: 5 Strategies That Changed My Life Book: https://geni.us/dxPr▶ Discovering Travel Bliss: Insider Secrets for Transforming Ordinary Trips into Joyful Journeys Book: https://geni.us/QzzEgjo▶ Money Is Factscinating: Fascinating Money Facts, History, Stories & Trivia Book: https://geni.us/LckBTAX----------DISCOVER FINANCIAL INDEPENDENCE:▶ Podcast: https://geni.us/N79P5UC----------FOLLOW ON SOCIAL MEDIA:▶ Instagram:   / expedition.money  ▶ Facebook:   / expeditionmoney  ▶ X:   / expeditionmoney  ▶ LinkedIn:   / expeditionmoney
