after suddenly breaking to a stop on a highwayfrom around 50 mph to 0 the transmission was frozen on trying to get back into first gear and driving on. After precariously inching back onto the hardshoulder (a few stalls on the way) in whatever gear in was able to get into (something like 4th) and continuing to inch along on the hard shoulder,
2 minutes later the gearbox slowly loosened up and it was as good as new ?This has happened twice
