Now it's got colder I've noticed a slight notch 1st - 2nd gear first thing in the morning, I can get around it by change gear slightly slower and after a few mins it's fine. Is this a sign of the clutch going? Gearbox oil was changed last year.

Try doint the gear selector align mate.

Cheers Billy, will give that a try

I found mine was much easier to get into second after I replaced lower engine mount (dogbone mount)
