Hello, my gearbox has started playing up. I did a few drag runs and my first one was fine. Done another one 20mins later and it would not go in 2nd, so I put it in 3rd, then it wouldn't go into 4th easily, but did eventually. After a bit of messing about putting it into all the gears whilst standing still I tried another run and it was ok.
But now every now and then whilst driving normally when I put it into 2nd the part of the gear knob that you pull up to put into reverse seems to go up itself when I put it in 2nd and 4th and it doesn't feel right, other times it can be normal.
I'm thinking its a combination of the oil/ heat making the oil thinner and something up with the selector part of the gearbox.
Anyone have any ideas what I can do from now? I'm quite happy to take the box out and have a fiddle...
