6L80 & 6L90 the WORST 6-Speeds? | Common 6L80 & 6L90 Problems that lead to DESTRUCTION!

Follow Cole as he goes through common issues with the problem-prone 6L80E and 6L90E transmissions, how to identify them when they happen, and why you want to NOT DRIVE your vehicle when certain symptoms occur. The 6L80 and 6L90 transmissions, despite being related to the robust 6R80 transmissions, have more than a few issues from the factory that makes them essentially time bombs. The PR valve within the valve body loves to wear, the OEM torque converters lover to fail, the pistons love to crack, and the clutches love get roasted.
