I did not have any trouble with the studs at all. I have a 2018 Z71 and am in the "rust belt" in south east Michigan. The total fluid that I had in my drain pan was just short of 7 quarts. I put 7 quarts in when I filled it.
I have a friend who has too big a belly to easily get under his Colorado for oil changes, so he has a slightly different excuse. I told him he just needs a lift kit.Sorry, but at a little over two Franklin's, and at my age, I gladly have my local Indy service the tranny.
I too have a larger🤪 belly. Since I have 6” of lift and larger tires I can slide under quite easily lol.I have a friend who has too big a belly to easily get under his Colorado for oil changes, so he has a slightly different excuse. I told him he just needs a lift kit.
did you have your truck sitting over night, its possible you had some drain back from the torque converterI got around to checking my level "by the book" with transmission level, and added about 8 ounces then let it run out, so mine took just slightly over 7.5 quarts which is what I drained out too. I have seen several folks refer to about 6 quarts for the pan drop and filter change. Don't know why they are seeing a difference but feel good that I verified the original dealer flush was right on as far as level with mine.
Advice: Use only GM filter and oil. Dont let anyone flush the trans. I am a trans guy.Could not find anything recently on this, sorry if I missed it.
Decided to change (some of) my fluid and filter on my 8 speed (it had the new fluid and flush at 2000 miles as a pre-emptive strike) now at 50,000 miles, but with S/C and a lot of towing near max GCWR and at high speed/high temp figured it could not hurt to change out the fluid and filter (not a flush).
At any rate, I can't get the trans pan to clear the crossover exhaust pipe to remove it, it comes very close but jams up. The service manual does not mention anything about dropping the exhaust crossover, so wonder what y'all who have done this encountered. Going to tackle it again in the morning.
