Hi I have a 2010 Mazda 6 4 cylinder automatic that will not work in reverse stays in park. If put it in drive 1st and 2nd gear works but when it shifts in 3rd, 4th or 5th it just revs the engine. This has just started to be a intermittent problem. Sometimes it will drive normal. And out of the blue it will do this. Anyone have an idea or where to start looking. Problem the nearest Mazda deal is over 2 hours away. Hate to take it to them when it’s not mess up. But hard to when it does.
