Consumer Description

My 2018 Sierra began experiencing severe shuddering while driving down the road. The dealer said it was caused by moisture getting into the transmission fluid and contaminating it. In my ownership of dozens of vehicle's this has never happened before. This formerly inexpensive minor fluid change requirement morphed into a $618.00 major surgery just to fix a problem that should have never occured. If the fluid was contaminated by moisture as the dealer explained, it's a design defect which caused it and nothing I have ever done. I am still unsure as to if the transmission or torque converter may be damaged. The manufacturer should be liable for the cost to fix this not me!
