I have a stupid question since I did something stupid. I have a new 2005 f150 4x4, I was driving today and I have been driving up to 60mph the last few days, and just noticed that my truck was in 4L it has electronic shifting. so what I did(not thinking at all) is shift it back to 2L without stoping I was going about 35mph, now I heard a grind then it went away. of course I said oh #$%&! but I stopped and shifted it properly and it seemed to still work. My question is did I do any damage it seems to be driving ok..
