Diagnosis Please (and give it to me straight doc)

Big R ED · July 1, 2020

Patient - 2019 1500 LD, 5.3, 6 sp, 7200 miles old, Covid-19 negative. Symptoms - 2-3 second shutter / shake / rumble, during light acceleration, 30-40 MPH and low RPM. Happens while both in V4 mode and while in v8 (manual w/ transmission set to L5). I thinks its the torque converter, but surfing the forum I see this issue mainly referenced to 2015+/- K2s and I'm not sure if they changed the trans in the final years. I'd appreciate either a TSB # or a link to another posting were I could find the TSB. I'd like to be able to take to my dealer and say "HERE....READ....FIX" (politely). Many thanks!

Unfortunately the bulletins for trans issues don't cover '19 old style, but I'm sure they would apply if the bulletin matches your problem. These may match your issue. I cant copy the whole bulletin(s), but it may help.
