Eljeffe316 started following Annoying Rattle, Behind Passenger dash or firewall, green screen, 2019 5.3l 8 speed jolt when accelerating and and 1 other
My 2019 AT4 did this for the first time today at 3k miles... actually thought I was rear ended it jolted so hard. Did feel like the trans slipped in some way. Just backed out of the drive and switched from R to D - also was on a cold start.
I’ve got it as well...as described it’s a plastic on plastic sound when the truck is cold. Started hearing it at 500 miles and now at 1000 it’s still there. Sounds way back in the dash footwell to me, will wait until someone figures it out before I rip everything apart.

I agreed, originally thought it was a gimmick... however, after using it I really like it. Having a bad knee (recent ACL) this gate is amazing for getting in and out of the bed - extremely easy!
