Today while salting the ABS light came on. After that the truck shifted alittle different than usual, kind of abrupt in the lower gears. I should say the truck I have is a '99 Ford F-250 Super Duty. All seemed fine until I noticed the ABS light on after seeing the warning the truck started acting as I described above. My thoughts are this is something electrical but I don't even know where to start. Can anyone help out.
