I think I found the exact reason this transmission ended up in the junkyard

In this video, I break down the transmission, inspect the internals, and show the damage that turned this 4L80E into a junkyard candidate. As someone rebuilding a transmission for the first time, I’m learning as I go and bringing you along for the process—mistakes, discoveries, and all. If you’re into budget builds, junkyard parts, DIY repairs, and figuring out how things actually work, you’re in the right place. 👍 Like the video if you enjoy this type of content. 🔧 Subscribe for more: 4L80E rebuild updates Junkyard finds Budget performance projects
