Awesome, thanks. Had the flush done and the symptoms are definitely improved. Can tell if the remaining issue is just in my head or actually there. Will have to drive for a while to know for sure.

Hi everyone, I have a 2019 sierra at4 5.3 with the 10 speed tranny. Currently has about 94000km on it (I'm in canada so km not miles). Couple months ago it started shuddering. Mostly a med to high speed when under slight load, like up a slight incline. Is gotten worse over time, and at its worst I can see the engine rpm oscillating by about 100rpm. Almost feels like it's hunting between 2 gears. Anyway, took it to the dealer today, and they said there's a bulletin to flush the tranny. Seems sketchy to me. Especially when my powertrain warranty is over in 6000km. Anyone experience the same or have any thoughts?

My brake wear monitor had failed prior to this. Was displaying "service brake monitor" so I just disabled it. Interestingly though, after I left the truck sit and cool down for a couple hours after the test drive, everything went back to normal and it's good to go. Very puzzling but happy with the result.

Hi everyone, I have a 2019 sierra AT4. Has about 70000km on it and the rear brakes needed to be changed so I did both front and rear pads and rotors. Everything seemed to go smoothly, and I got a bunch of the ABS codes on startup that I read about. I cleared those codes and things seemed better. After going through the brake bedding procedure, the fronts are now dragging to the point that they're smoking when I stop. Any idea what could cause this? Doesn't make sense to me as there's nothing to be binding with this new caliper design. Thanks in advance
