I have a 2021 8spd 5.3 with same shudder. It's been at dealer for 2 weeks and supposedly they are waiting on a gm engineer to tell them what to do. I noticed in an older thread but a 10spd and fuel injectors fixed it which is pretty much like a misfire so I guess it makes sense. I highly doubt it's that thermostat.. thats just because they put in too high of one and if towing the trans will overheat...
2021 lt with a mix of rear bilsteins and blocks, front is rough country 3.5 replacement struts and belltech upper arms. Still stock 18s and little tires but so far I love it!! Haven't decided next tire size yet but it will eventually come. Ive also added rear suspension suspersprings [black] for towing.
Where can you buy just the seats? Wonder if I can even add em with just an lt optioned truck. I almost bought a used ltz for the seats alone... heated seats where I live is absolutely worthless!!
Man you got that for an insane price...wish I could find the same for time being....my truck is an absolute dog. I had a hike it controller [amazing] and it made the truck fun but I had the trans rebuilt so I didn't put it back and want to tune everything..especially trans. Sent from my SM-N960U1 using Tapatalk
Yes sir..... personally these are plenty big for me. I have two jeeps as my toys... this trucks a pavement pounder. For that matter these tires are noisy as hell!
