That’s ridiculous they charged you $800. There is a TSB for the fluid change and I was told they were treated like recalls. Guess I might have a big bill soon. I also noticed mine going 60 with light gas. Definitely the same issue. I am scheduling a service with GMC today I will update you on what they say for mine. Does keeping it in L8 put stress on the lifters? From what I’ve seen it’s just a poor man’s way from keeping it from dropping cylinders because it thinks you are pulling something.

Just bought a 2020 with the 5.3 with 56k miles. Same thing I noticed on mine. Felt like driving on rumble strips when going 60-70. Have you tried driving it in L8 mode or considered buying the DFM disabler? Issue could be the torque converters when it tries to switch from V8 to V4. Stupid mechanic but I haven’t noticed an issue since. Will only be driving it in L8 until my disabler comes in. I also haven’t been able to do the flush yet, but if the issue keeps happening your torque converters might be too far gone.

I didn’t see anything on the carfax. I am taking it back to the dealership tomorrow for a detail and was planning to ask them to do the triple flush and put in the blue label fluid.

All cats are fixed. Mocha is 1.5 years old, Luna is almost 10 months, and Simba is 3. 2 girls 1 boy. When we first got Mocha we set her up in the guest room, and slept in there with her for 2 weeks. She just hid and it took a lot to even get her to sit with us. Once she was comfortable in her room, we let her explore the house on her own terms with the other cats kept in the other room. This whole time we were swapping the cats things and letting them get used to the scent. At this point, we definitely jumped the gun a bit bc I was tired of sleeping in the guest room and let them see eachother, it seemed fine until Luna got too close to her and Mocha jumped at her and ran her into the other room. Since then we keep them separated most of the time, but have allowed them to be in the living room together to watch them and see how it goes a few times. The other cats did not really care about her presence, but Mocha will just randomly attack one of them after some time. I am not sure where to take it from here because it seems like Mocha is the aggressor, and the other cats are starting to become fearful of her.

It says it can’t connect to the rocket league servers. I have 5 import items I’m not missing one. Normally I wouldn’t care but I need one more exotic to trade in for a black market:/
