We Tested 10R80, 4R70W & 6R80 After 200,000 Miles — A Clear Winner

Which Ford F-150 transmission actually survives 200,000 miles the best? 📘 FREE Ford Longevity Checklist 👉 https://fordscope.gumroad.com In this video, I put three of Ford’s most important truck transmissions on the teardown bench at the same mileage: the 10R80, 6R80, and 4R70W. One transmission looked nearly new at 200,000 miles. One showed wear patterns that point toward an expensive rebuild. And the oldest transmission in the test embarrassed both of them. Using real-world wear patterns, fluid analysis, valve body inspection, torque converter condition, and documented long-term ownership data, I break down what actually happens inside these transmissions after two decades of work. If you own an F-150, are shopping for one, or want to understand which Ford transmission has the best long-term durability, this video is for you. 📙 Ford Longevity Guide (full system) 👉 https://fordscope.gumroad.com/l/bluep...
