Ok, I have a little problem with the auto transmission on my 2007. 5. After ideling over 10min or pulling a load for a short period of time the unit will shift very hard into drive. (so hard that you can not hold it with the break and it will move foward about two inches). Now the problem is that if you kill and restart the unit it will not do it again. Of course the dealer thinks that I am crazy even after showing them mutiple times that it is not fixed and mutiple dealers. I dont know what to do, it does not throw any codes, and I love the truck, but with 25K on it, I am getting a little concerned. Also, I dont know if it has anything to do with my problem, but 4WL will not come out, so you have to kill the truck to get it out of 4WL. Any advice would be great. Thanks for your help.
