Driver Information Center
To enable the full function of the DIC, you'll need the DIC buttons.
The DIC wiring is behind your dash when you pull off the cover, you just need to hook it up to the switches.
Final tally on tranny temp for my trip, when I went through Mt Rushmore, due to my inexperience of manually downshifting, I overused my brakes and thought I might go off a cliff...lol not really that bad but definitely had a few pucker moments. I reached temps of 206 with outside temps of 85-90 degrees.
The next day when I was driving through the Rockies I manually downshifted every time I encountered a downhill segment, and actually saw my tranny temp decrease, and then rise again as I would climb the next segment. the highest temps I saw climbing were 212 in steady 90 degree temps. The last day was a scorcher with temps around 105-106 and going through the Mt Rainier area of WA my temps jumped to 221 on the worst climbs. Once again I manually downshifted on the downhill segments and the temps dropped a little.
If I were to do this trip again, I would seriously consider the all-wheel disc upgrade. My current brakes are also 6-7 years old never been reworked, but only have 40k miles on them. They seemed very inadequate pulling the trailer and bike through the mountains, until I got comfortable downshifting that is. I would also re-read the operator manual and know exactly what my manual shift points/speeds are.
I hope my rambling on puts some perspective on tranny temps, and what to expect from your ride.
Glad your trip was OK. I'd give your truck a gift of slotted discs and ceramic pads on the front end. Your temps are fine, my truck runs at about 200 degrees in the summer or winter, no difference, my other car (also a GM) will go to 210-215 degrees if it's 100 degrees outside with 75% humidity. so I wouldn't fret over you temps, You truck is running perfect. I am planning on the brake upgrade I mentioned come fall. When I'm towing in high temps I can feel my front brakes getting hot and slipping, so I'm going with better disc's and pads. :great:
They are a real upgrade for the front end of your truck. Most of your braking power is on the front wheels. The ceramic pads need to be broken in or cured after installing them, not complicated, but the ceramic pads give off very little dust, but the best thing about them is the hotter they get, the better they brake your trucks speed, No fade !
