My 40,000 miles '23 LZO has no rattles.

The 10 speed behind my LZO runs between 190 and 200 winter and summer. In colder ambients, it takes longer to get there -- but it does.

Are you saying that if you hold the button in the up poistion it will not travel up or the auto function will not raise the window?

No advice to offer, but pre-refresh trucks work differently than refreshed truck

Every dealer in front license plate states or provinces will be able to fix it up with the conversion kit.. If the vehicle is factory shipped to a license plate state the parts (rpo VK3) will be factory will installed.

GM might decide to limit speed below the trating of the tires (for whatever reason). Hard to believe they would even think about accepting the liability of having the vehicle speed limiter above the rating of the tires they installed. Will tires fail immediately if rated speed is exceeded? --- of course not .

https://gm-techlink.com/?p=14641 Diesel Engine Rear Main Oil Seal April 13, 2021 Some 2020-2021 Silverado, Sierra; 2021 Tahoe, Suburban, Yukon and Escalade models equipped with the 3.0L diesel engine (RPO LM2) may have an oil leak concern and DTC P06DD (Engine Oil Pressure Control Valve Performance) may be set. These conditions may occur if the rear main oil seal has moved or is severely shifted out of position in the timing chain lower cover. If these conditions are found, replace the timing chain lower cover, which comes with a seal already installed. (Fig. 9) Fig. 9 If the seal is tilted out of position, use a caliper and record the depth where the seal is pushed in prior to removing the rear cover. Also place an indexing mark on the seal and cover, which will be helpful to the Warranty Parts Center in case the seal falls out or moves during shipping. (Fig. 10) Fig. 10 Record the Part Unique Number (PUN) found on the white label attached to the back of the cover. The timing chain lower cover comes with a two-piece protector/installer. The inner piece becomes the installation tool. (Fig 11, A) The outer piece simply holds them together for shipment. Remove and discard the outer piece. (Fig. 11, B) Fig. 11 The inner piece acts as an installation tool substitute for the EN-52466-2 seal protector and fits over the bevel on the end of the crankshaft. Be sure that the inner lip of the seal slides over the rear of the crankshaft without rolling during installation or a repeat oil leak may occur. The protector/installer (Fig. 12, shown without cover) will have a snug fit to the pilot of the crankshaft. Fig. 12

Stretch belt install/removal is tool is about $30 and fits in the glovebox or pocket in rear seatback or.... This one is a Lisle

And be careful where and how the pressure was wand gets applied.

Do you stop filling the first time the fuel nozzle clicks or re-activiating it multiple times to squeeze in as much fuel as possible?

Can't answer your question about the 8 speed, but how are you liking the 2.7T ?

And of course the spring loaded idlers also have bearing failures.

I use cruise almost every time I'm in the truck. Adaptive cruise is another tool in the kit. For many years I manually operated regular cruise to 'sorta' behave like adaptive cruise. Hit pause to slow down when approaching slower traffic that I can see I won't be able to pass. Bump the controls up or down to maintain distance when pacing others. Sometimes on longer trips it was a sort of game to see how many miles were possible without needing to use the brakes or throttle. I find that I need to interact with the controls for cruise much less often when it's set to adaptive cruise. And of course in some traffic situations -- I'm mostly thinking about heavy commuter type traffic on limited access roads -- neither type of cruise is usable. I've never been in a vehicle with 'super cruise', but I wonder how well it would behave in those situations that regular cruise or adaptive cruise don't work well? We also have a mid-size GMC suv with adaptive cruise. I don't like it's programming as well as the Sierra..

IIRC, the L76, used in the 1500 was an aluminium block engine The L96, used in HD's until recent change to LT8 was cast iron block LT8 is cast iron block
