I bought this 2018 Tahoe Premier in August of this year, w/94k on the odometer. The Chevy dealer gives a lifetime warranty on engine and transmission on all vehicles under 100k.

Carfax showed that the previous owner had the transmission replaced in June of this year. So I figured with the new tranny and lifetime warranty, I shouldn't have to worry too much about transmission issues, if any, for a while. Well last week (with 101k on the odometer now), I started to get the dreaded "shudder". Felt like I was driving on rumble strips at times, and the transmission would shift a little hard sometimes.

I made an appointment to see the dealer. Appointment is 2 weeks out.

So I was driving it yesterday, and it seemed like it was back to normal. No issues. Then it started to have a hard time changing gears. Then it got stuck in a gear and wouldn't change at all. Called tow truck and had it towed home.

Is there ANOTHER new transmission in store for this Tahoe, or do you think it's a smaller problem (torque converter)?

Doesn't sound good. Mine was shuddering. Needed a new torque converter. We ended up doing a full rebuild anyway.
But it does seem like if the thing was installed in June of this year there should be some kind of warranty. Good luck
