Car shifted into gear when in park...

The lokar cable has nothing to do with it. That is used just for throttle pressure. It's in your shifter cable or the shifter. BE CARFUL! The only way it COULD be something with the throttle pressure cable is if you have the levers on the transmission rubbing on each other. Make sure when you give it throttle the (top) level is not interfering with the shift lever (lower)
