Plenty of discussions with the dealer and techline in regards to the operating temps that GM set forth on the powertrain for our Tahoe. They said both engine and gearbox temps were normal and as expec

They'll get to the 8 spd once it get's closer to the end of it's life cycle.

End of the day it all came down to CAFE/Fuel economy ratings.  The faster the trans got to operating temp, the faster it could produce less friction, the faster it gets better fuel economy.

Thread divergence: @Blainebug: out of curiousity, from your sig, are you an ACVW guy?

No, username has nothing to do with the Volkswagen Beetle.

Correct me if I am wrong but here are 4 lines I see running to my radiator and the condenser up front. 2019 Yukon with active aero shutters in the grille.  All 4 lines are the same quick disconnect style with the clip and plastic retainer.  Are all transmission related?  I didn't think the A/C lines used quick disconnects like these, but I'm also not sure where the engine oil cooler goes.  As far as I am aware there was an engine oil cooler.  I do not have a factory towing package, as in, no integrated trailer brake controller in the dashboard and no 2-speed transfer case (2wd, auto, 4-hi only.)

I'll have more cold weather data here shortly.

Its around -13F here this morning and I have to drive about 22 miles. I'm expecting it to get up to around 100°.

Temp was -12°F , around 15 minute warm up. 

Trans temp was 37°F out of the driveway. 

Drove a mile to Dennys. Trans now 60°F.

Shut truck off for 20 minutes. 

Remote started it when I finished my eggs. Ate the rest of my grand slam and I was back in truck exactly 30 minutes later . Trans now 64°F.

Drove about 8 miles at 40 mph and stopped for gas. Trans now 118°F.

Cooled down to 114°F while idling 4-5 minutes. 

Drove another 12 miles at 55mph and watched it drop to 88°F. 

I think if I got on the interstate she would really cool down.

 

I got to think about this. I got at least 2 more months of below zero B.S.

I'm not really feeling crawling under it and re flipping it.

I'm also not feeling the 158 kit 

I like it flipped when it's hot in the summer.

The 158' kit is worthwhile.  If you're like me you can sell your original setup for $40-$50 and be into the new thermostat for only around $20 😁

If someone is going to tap and drill the old housing for a plug I'd rather have a spare on hand just in case something cracks or gets damaged in the process rather than being out of a vehicle for god knows how long.  That's the value in the old units.

My pill is flipped.  That was Free.

I don't drive a ton in the winter so I may just leave it

Just walked out to our 19 Tahoe with aero, tow package (not max trailer).

 

Based or RPO we have aux trans and aux oil coolers. 

 

Pass side:

Two larger diameter go to the radiator for aux oil cooling. 

One small diameter is trans to condensor supply.

 

Driver side:

Condenser trans return

 

KC4 - oil cooling system

KNP - HD aux trans cool

Z82 - trailering equipment

NP0- single speed t-case

I don't have an integrated brake controller or two-speed transfer case so I doubt that qualifies me for the tow package (not sure what the difference is between tow package and max trailering package.)  However I did request a build sheet from General Motors and it is listed that I have "KC4 Engine Oil Cooling System" and "KNP Transmission Oil Cooler."  I also have "Z82 Trailering Equipment Package."  G80 rear locker with 3.08 gear ratio.

As mentioned, neither do I. As well, two small diameter go to condensor. Double check your two larger diameter on the pass side, I bet they actually go to the radiator.

I believe 1 and 3 go to the condenser and 2 and 4 go to the radiator in my pictures.

PS, is your KNP really labeled "heavy duty auxiliary transmission cooler?" That is not what my build sheet says.

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w
