clutch was replaces last year so that was fine.
i did use gear oil additive in the old box but didnt make a difference. it must have been the diff that was noisy as the noise was present in all gears. when i went to Ace the noise defiantly got worse, so much so that i was embarrassed to drive it in gear and my mum was worried that the car would stop, thats how bad it got.
the new box will be left as it is, as in just oil and no additive
