I took my 24 Sierra Denali 4wd in at 37,000 miles. Had the mileage maintenance checks done, asked them to change out the two limited slip differentials, including the limited slip additive, and change out the transfer case fluid. They rotated my tires, verified my shocks weren’t leaking, and whatever minor checkouts that were on the list for 37,000 miles. About three hours later, they charged me $600 and sent me off.
I was considering having the 10-speed transmission serviced, but between the posts on this forum and previous experiences with transmission failures after a fluid and filter change, I decided against the tranny fluid changeout when the service advisor told me it would take about 3 hours and cost about $500. After growing up working in three different full-service gas stations, I know to stay far away from flushing machines connected to any automatic transmission.
I don’t meet the severe duty schedule, but I may follow the 45,000 mile tranny service, unless
i see more problems from doing so on the forums. I expect I will want to watch the entire procedure. The various utube videos do a decent job of showing how much time and attention should be taken for a correct fluid &filter replacement, so witnessing the procedure seems something I should do. Trust but Verify🥳
Otherwise, I’ll follow the owner’s manual recommendations, whatever they are.
Bring this old post back.....
@Rally6.2RST in your list of part, you bought a "1 camera I used for rear ($70) 23390514", why exactly did you buy it ? Asking because your car already had a read camera, right ?
Thanks
Have you considered using a 90degree downward hdmi adapter? I am going to try it once mine arrive- my kids already broke two wires in a span of 2 weeks
In Arizona- just got her about two weeks ago, have put 1,000 miles on it both highway and city driving between phoenix and California along driving it back to phoenix form Las Vegas when I got it.
Anyway, I failed smog because the catalyst was “not ready”
anyone else have this issue?
edit- 2021 Yukon denali 6.2 l87 10speed
Looking to get some insight into why a 2023 GMC Sierra 1500 8-speed SLE 2.7L L4 would shudder when accelerating around 80-100 km/h (50mph to 62mph) between 2000-3000RPM. It began doing this last winter, and hasn't been used since, but it continues to have this issue. I used to be able to sustain the shudder for longer, but now it only lasts about 2 seconds.
