My 2019 Silveraldo has started to shutter going down the road and sometimes it sounds like rumble strips. I checked online and this year and model did have issues with 8 speed transmissions. I took it to a local garage and they were tooo busy to test drive but said it is no doubt the converter. Another place said I could do a flush and fill of the transmission fluids and see if this helps. What is your suggestion?
