Anybody having this problem..... I don't know what to do to fix this. 07 1500 4l60e Will not up shift to Second speedometer drops off and reads zero . If I stop the truck and put it in park then into drive this goes away ...does this randomly. I've read everything from Bad VSS. To bad ignition switch. To broken snap ring in transfer case. I'm new to this forum so I'm hoping I'm not ruffling any feathers here or posting to the wrong area..... if I am I apologize
