I´ve blown a clio 1.6 16V gearbox (and a couple of months later I´ve blown the engine...). I´me getting now a 2003 172 and I am worried about the gearbox. Many people had problems with the 172 gearbox and many other people talked about doble clutching and some other stuff they did to shift quick and not blowing the gearbox. PLEASE HELP ME TO KEEP MY FUTURE GEARBOX IN ONE PIECE !...
