When I bought My last Camaro in March of ‘21, the tranny would shudder on inclines. It also would seem like it wouldn’t shift right every once in a while. Two days after I bought it. It was a 50th anniversary 2017. I took it in to the dealer, and immediately the transmission tech knew what the problem was. Sometimes the Camaro would act like what everyone is talking about on here, and, I’ve experienced it with My ‘19 Blazer. The fix? They changed the tranny fluid to MOBIL ONE. It didn’t ever do it again. In a week I’m going to go get MOBIL ONE TRANNY FLUID put in, MOBIL ONE oil put in also. I’d like to get the throttle body cleaned, My ONSTAR is not connecting, maybe just an UPDATE ISSUE, and have the dealer do the full inspection of everything! If I’m keeping this car and going to pay it off before I retire next year, it had better be right! By the way, the tranny problem with the Camaro was on the ‘16 and ‘17s. And You can GOOGLE it and it is right there. I couldn’t believe My eyes. Might not be the same but worth a shot! I’m starting to wonder about these newer Chevys..new Cars period. Are they selling us junk?
