I have a 2018 Tahoe with the 6L80 tranny. Did it come from factory with Dexron VI? I have 21k miles on it and it’s still clear /slight pink.

Maybe I was being harsher on my fluid than it actually is.  At 35,400 miles presently.

 

I believe I would ignore the seriously dirty portion when I wiped the entire length of the transmission dip stick.

 

The two other areas are soaked into the napkin somewhat but are more representative of the fluid that comes from just the very tip of the dip stick that is submerged in the pan.

I wouldn't say it's bright red but looks relatively pink.  Davester's looks worse.  It's probably a bad idea to wipe the entire dip stick when going for a measurement of color.  Even clean metal leaves a residue when it's wiped.  Not sure why that is but it happens.

It's the clutch material, it goes up the dipstick tube as a dust and coats the tube and dipstick. Mine has it too.

Makes sense.  Although it doesn't seem like it matters what or where metal is, if it's raw and un-coated it will give you a sort of residue if you wipe it with a rag or towel.  Not exclusive to dip sticks.

      2007 Silverado classic Cooling fan running

      By Mistycool · Posted

      I am having similar issues.. 08, 4.8L granted I did had a fender bender and minor damage up front passenger side but I don’t think it had anything to do with it.. I had the high and low pressure checked and my fan for my radiator keeps coming on.. replaced the pressure switch and don’t want to keep throwing parts at it. I did have some minor problems here and there like on long road trips sometimes the ac would get a little warm and then on the highway as soon as I give it a little gas or get a little heavier on the petal it started running cooler. Never had an issue with the ac besides the here and there.. but I also started having issues when I fuel up now it takes a bit to start ( super embarrassing) it runs fine and once started ( only happens after fueling up) starts fine any other time. Could they be related?

      Spent a small fortune on fuel this weekend.   $6.69 diesel, 18 gallons of that. $6.99 92-octane ethanol free, 10 gallons of that for yard machines $5.59 87-octane for one of the cars, 11 gallons.   $250+ and I didn't even get a tug.   Hormuz ain't Hormuzin again, did not see that coming...LOL

      Appreciate the advice. I've watched multiple videos. Most showing the most complex for those that have a center console, to one that showed maybe 2 pieces of trim being removed, like 6 screws, pulling back the screen and switch assembly, and installing the inline module. And this was a new/newer Silverado. That didn't look too bad. All the others show alot of trim pieces that need to be removed. I've broken those kind of tabs/clips on my C8 Corvette trying to get to the battery, and that was a lot less clips than what I think is involved here after watching multiple videos and looking at my dash today. I have one on the way. Called a reputable stereo place about installing it and got a "minimum" price of $175. Ouch! Looking forward to seeing what the instructions have to say.

      Ac not keeping up

      By Atlas · Posted

      Hard to say what the issue might be. Anything from the ability to cool the AC condenser up front, to blend door issues in the HVAC unit, to refrigerant charge, to compressor issues or issues in the lines.   Report back what the techs find on the 29th.   GM has service publications which list acceptable vent temperatures and AC pressures at given ambient temps and humidity. They probably won't touch the system if it's operating within those ranges.   I'm also surprised to hear your 2024 with the L8T is still using R134a? I was pretty sure the HD's had switched to the new refrigerant around 2020.
