Sthdrider2000

Had the same issue with my 2017 Sierra 1500 4x4 slt. Had to replace transmission at 108,000. Not happy about it as I take good care of mine as well. Always dealer serviced. I’m a GM employee so my dealer gave me a discount on it. Normally around $5,000 to replace. My cost was $4,000. Absolutely pissed! $54,000 truck should not have these issues!! Torque converter was the culprit. I’ve read of this happening to many others.
