My honda vezel gives a P073F error that describes as Unable to engage Gear 1. The issue pops up all of a sudden normally as i start the car and put it in gear once in every 10 times. This goes away once i shut down the car. Has anybody faced similar issue. If yes what was the remedy. Most mechanics want me to replace my dual clutch. Others want me to change my gearbox. Can somebody explain me exactly what is happening?
