Hey all, when I drive my 2019 Impala normally it seems fine. However when j accelerate hard it seems to have issues shifting from 4th to 5th gear. It starts shuddering severely. Its like it can't get into the next gear. If I take my foot off the gas it calms down as the rpms and speed reduce. Any ideas what is going on here? Is this a known issue with the 6speed transmissions? I think it is transmission because I feel the shuddering in my seat not in the wheel, but the whole car shudders when this happens.

 

Take it to the dealer for warranty repair.
