Hey all, I've has my 2021 camaro 1ss for a few years now, and starting of 2023 it started acting up on me. At first it wasn't really a problem and went away after a bit, but now it's back and it happens every time I drive. When coming to a stop, and it downshifts like normal, right when going to first gear, the tachometer dips down hard to 500 rpm and even below that, then the vehicle stutters like its about to stall, then goes back up to idle like nothing happened. I'm very confused on why this is happening... I took it to the dealer and they said they didn't find any codes stored... I'll take it back again soon since it is getting worse in the cold now that winter is creeping up. But before I do, I want to hear everyone's thoughts about this and can help me out. Thanks. I've attached a brief video of this happening. You need to turn your volume up to hear it making a weird noise (sounds like it needs a new serpentine belt kinda sound) followed by stuttering.
