What is normal transmission temperature?

Hello,

What should the normal transmission temperature be for a 2011 Chevy Silverado (not 4x4)?  My gauge (on the right-hand side of my dash) always shows the temperature as straight-up 210.  But, when I press the button on the left-hand side of the dash and check the transmission temperature control there, it showed about 159 degrees (F) this morning.  Why don't these two match?  Should they?  What should the "normal" temperature be?  I am in Texas.  Right now, the temperature outside is about 32 degrees (F).  I had my transmission rebuilt about a year ago with the Chevy dealership.  I have about 117,000 miles on it now.  Yes, I have read my manual - it's not very specific on this matter.  I do a lot of highway driving (almost every day), so I need to make sure I am OK and don't get stranded somewhere.  Please help!

Thanks in advance!!

They don't match because the gauge on the dash (right hand side) is the engine temperature gauge...normal temp on it is around 210°F

Transmission temp is shown when scrolling through digital readout on the DIC.  159° is in the normal range for regular driving...towing or hauling will cause the transmission to work harder, causing the temp to go up some.  The temp you are seeing, 159°, is well within the normal range

If the transmission temp ever gets too high, it will throw a trouble code, and you'll get a warning chime accompanied by warning light and warning message in the DIC.  If none of that is happening, you are within normal operating parameters.

      Around 2008 if memory serves they took sulfur out. That was when diesel went up.

      Question for you Grumpy, why is diesel so much more than gasoline? Seems to me that it may be slightly a little less refined than gas and it doesn't have 10% alcohol which presumably lowers the price of gas

      Thanks, so being a different beast altogether, anyone know what the "optimal" temp is for the 10L80/90 for proper shifting?

      How many years have I pointed out every point in that link to the folks here and been avalanched with criticisms and outright hostilities at times? I ran counter to even the great CUSTOMBOSS and Lake Speed Jr and the half dozen experts on YouTube and in the final.....GM, Physics (Stribeck) backs that Grumpy old Bear.    Honestly, I never said a thing engineering hadn't studied silly and laid in concrete during WWII. But I'm old, the information is old and yet, the Laws of Physics are eternal.    Okay there is one exception. I vehemently disagree with their use of the word 'tolerances' when what it meant is "clearance".   The clearance is the distance between two objects. The tolerance is the degree of acceptable variation permitted in that clearance. I.E., piston to bore clearance is 0.004" with a tolerance of +/- .0002" so the clearance is in specification if it lies between 0.0038" and 0.0042". Cutting that 'tolerance in half has ZERO impact on lubrication requirements. Makes for more difficulty in manufacturing.  But a tighter clearance 'MAY'. Depends on finish. Anyway....   It's one of those statements made by people to make themselves look smarter than they are to convince people who are as un-enlighten as they seem to manipulate their behaviors. But hey, the blind leading the blind puts them both in the pit.

      Out and about yesterday on a long Saturday drive I passed a lot of Shell stations. My preferred, so I pay attention. Lot's of small town Illinois so not six stations in three blocks like the city.    Everyone of them over a radius of say 100 miles had regular at $4.19 but one which was the one closest to home at $4.15. However Premium pricing varied greatly between 85 cents over regular to $1.50 over. I'm not counting the price of the station with the lowest regular so the reference is the same for the remainder and all within the same brand. However the spread discrepancy holds across all brands.     @txab, any thoughts on that?
