foracle

I normally have it slightly above ground and straight. Angled tends to tip one corner too low and tap ground. I have it as low as I can to get as much air flow. Sometimes I just sit with the hood up for 20 or 30 minutes and let the temperature drop. But I will check out recommendation. Thanks

Thanks! They sound like what I had in mind. But its hard to know if my opinions, based on theory and no real mechanical knowledge, are on the right track. And its hard to separate real solutions and quality products from gimmicks. So thanks for the info!

I want to start by saying i understand i am working my truck a tad hard. And I AM going to continue. I just want to protect it as much as possible while doing that. I have a 2014 silverado with the 4.3 v6. 102,000 miles and never a problem. Owned since new. When i haul heavy up gravel roads my tranny gets hot like....220-240. I am a carpenter and pull materials and box trailers. I installed a snow plow this year which is snow moving so not a lot of air moving past radiator. I have hit 250 before. I had the transmission flushed at 50,000 and again at 100,000. But i would like to get my temps down. I am thinking an aftermarket fan? An additional tranny cooler? From what i read the tranny cooler is basically built into the radiator. And because the engine runs so hot you wont get too much cooling ability. Also it dosnt start actively cooling until 190? So i guess i need to adjust my thinking to the trucks 190 and up temperature range. But I am not happy with 230 for hours on end. I dont plow commercially just a few small drive ways. Any technical advice, not just opinions(lol) would help.
