So hear is the short of it. Asshole in a Porsche cuts me off. I have to slam on the brakes and my puppy flys up to the front of the cab knocking the selector into Reverse. I didn't know that it got knocked into reverse and I hit the gas, and the truck just revs up and that is when I looked down and see it in Rev. My question is, is there a safety that is in place so I don't screw up my transmission?
