In the morning when I first start off, I feel a surgeing when I come to a stop. It's almost strong enough that I sometimes have to put it in neutral. I first noticed it after my last flash and thought it was just me, but now I know better. Seems like it's when I have my trailer on, but it stays on most of the time. After the truck warms up, I don't seem to notice it. The engine rpm's raise alittle but the brakes doesn't even stop the truck without really putting your foot into it. Maybe it just needs to warm up alittle more ????
