vehicles with trans temp readout

My Suburban has a digital trans display as well as each tire pressure. Should be on all 2007+ GM full sized SUVs.

60 degrees over ambient? Ha - maybe towing a pop-up on flat ground...

Our 2002 Burb has an instrument panel gauge for transmission temperature, but I use a scangauge which is considerably more responsive and accurate. On an 85°F day and towing our 8500-9000 pound TT on flat ground at average highway speeds, we'll see transmission fluid temps of about 160°F. On a long hard climb it's not uncommon to see the tranny temp get up to 220°F for short periods. Since that's about as high as I want to see it, it's extremely helpful to see just how long it's up there and how quickly it comes back down.

I'm afraid the built-in instrument panel gauge doesn't show the true temperature until damage would already have been done. I'd recommend something like the ScanGauge for anyone who's really serious about protecting their transmission.

The GM trucks all do this but it is less helpful than you might expect. My trans fluid reads about 60 degrees hotter than the ambient air temp. If it is 60 degrees outside the fluid will run at 110-120 degrees. When it was 113 on a trip last month the fluid temp go up to 178 degrees. I am not going to drive it any differently regardless and the same applies to the tire temps. When cold the front will be at 65 and rear at 80 PSI. When they are hot they pressure goes up 8-10 PSI but so what?

I am not going to do anything differently in my vehicle checkout routine or maintenance or driving as a result of having this information. If the tire pressure seems low I am going to check it with a hand gauge which is no different than if I looked at the tire and it looked a little low.

Trucks are the most profitable vehicles sold by the manufacturers so they keep adding gadgets to justify their very high prices.

2012 Chev Silverado 1500 can display trans temp on info screen.

My 2012 F150 Lariat does, needle gauge and digital readout on info screen. Don't know if that's standard or part of the trailer towing pkg.

I have a needle gauge that shows trans temp in my truck....
