I got this but miss placed where i put it just found it but installed another one in my truck but i sold my truck so don't need it. these sell new for $160.00 so I amd FIRM on the PRICE. will work on both 2wd and 4x4 this is a great add on for your towing lowers your trans temp by 25*. I loved my truck when I installed it took about hour and half never had to remove the trans can be done with it in the truck everything is under the pan and the valve body. easy job.
