[QUOTE="Boxxerace, post: 1114545, member: 16687"] Yo Mike and others, While stuck in some wicked traffic on 520 on Friday afternoon, I watched at the transmission temperature and radiator temps got fairly high. I kept the truck in nuetral when not moving and once I saw the radiator temps rise above the standard 210', I turned off the AC and put on the heater to help dump the extra heat. The transmission peaked out at around 220 until we got moving again. The truck: 1500 GMC Sierra, 2008 model, 4.8L V-8 with 4 speed autobox [IMG]http://www.gmc.com/images/gmbp/48012/vehicle/2008/med/2008317_c1_b21.jpg[/IMG] Am I looking normal operating temperatures (with bad traffic, warm air temps)? What is the safe range, primarly of the transmission, before the tranny fluid breaks down? Nice truck otherwise. [/QUOTE]
