This issue has persisted since 2019-2020 hasn’t gotten better or worse. When reaching up to speeds of 40-45mph I’ll get this shudder or vibration that you feel mainly in the peddle area. It’s only if I accelerate slowly at those speeds. If I give it gas before then I’ll shift right past it without issues. I’ve read many people complain about this. It’s not my trans fluid and it’s not my spark plugs. Car is currently at 121k miles and this started around 65-70k miles. People have talked about it being torque converter but some have had that done and still the issue persists. The only other things I’ve heard about this is it’s software related. I’m not paying $3-4k for a torque converter that’s if that’s the issue.
