Graphite1500

Very similar sound. This is what the techs noted.. 2021 silverado 1500 6.2L with 300 miles. Brand new

Just bought a '21 6.2L 1500 with the 10-speed. There was a squeak noise coming from the transmission. The dealer already knew of this issue since it was referenced on the initial inspection. The idler/driven gear on the trans pump is out of alignment. They're pulling the trans next week.
