I am female so I will describe the problem. This morning I started my van and the speedometer and the tack would not work the gas and the oil gages work fine. But also when I am driving I have what I call a glitch in the drive. I will be driving then in feel like a very hard shift. I can feel the pull when it does this. My question is can both of these issues be the same problem? Can it be that I have a bad computer switch? PLEASE HELP!!!!
