Shudder issue

For the past 3.5k miles, my 2018 MH (62k miles) has had a mild but worsening shudder when accelerating between 50-60 mph, which stops as soon as i let off the gas or go faster. It doesnt throw any codes, so i'm holding off on diagnostics for now, though it's tricky since the issue only happens under specific conditions.
 
I had a similar issue with my 2016 Malibu LT around 70k miles. Felt like there was a light vibration right in that 50–60 mph range, only under load. Turned out to be early signs of a torque converter issue. No codes either, but a transmission fluid change helped smooth things out for a while. I think you can check if yours is due for service.

Thanks. Did you notice if the vibration came back quickly after the fluid change, or did it last for a while? Also, did you end up having to replace the torque converter eventually??
