Got a little bit of fun for you guys lol... So I've been having this problem with when going into reverse sometimes the gears crunch only sometimes though so took it to mechanics today and he said yes definatly needs new clutch.. But about 30 minutes ago when putting into first and driving off it had slipped out of gear a couple of times and made a big thump.. it felt like it wanted to slip out of gear on 2nd and 3rd too ..is this the gearbox or the clutch?
