I dont know a thing about how these work but, I learned the hard way. I was at a car dealership I sell to. couldn't get my Bucket to start, Using my remote jump starter switch,with my knees on the ground jumped my starter, it started but was in gear, well I thought it was just rolling in neutral but it was in gear, Duh I tried to get up, as well as hold it and just dragged me on my knees till I was smart enough to let go. after I got up it was on its way through the parking lot and about to hit a wall. Thank god the parts manager managed to reach in and push the brake. I had to change my pants after that ordeal. Scraped up knees, Well I'm about to replace my hurst shifter pro shift 2 with something? any recommendations. The neutral switch will not allow me to start the car without putting preassure to the right against the switch, and the switch alone it $45.00. Sloppy wiggle shifter anyway so I might as well get a new on.
