    I kinda think that might be a reference to what my problem is we're kind of the same thing all the gauges will just drop all the lights on the dashboard trun on but the motor keeps running and it keeps driving but if it has to change gears that doesn't happen and basically you have to cut it off and turn it back on for the resume normal function..
