ok, I bought a 2007 silverado 1500 with the 4.8. It has the tow package but apparently not a transmission cooler. I transfered my suburbanite plow from my 02 f150 and just had it installed on this truck. The problem is, when lifed the plow is only like 6" off the ground. While driving home from the plow dealer my trans temp was at 205. No lights or warnings came on but I was monitoring it on the built in computer. I'm sure this is too high, especially for just driving. I'm guessing the plow is blocking all air flow under the truck and this is the problem (i was on the highway traveling at about 75mph before slowing to 65) any recommendations!!
