I have finally sorted the right spec gearbox oil and now changed it, I would say it has improved the change by 30% it now feels dare i say it normal, Its still mechanical and precise but no longer slightly annoying it does what it should and i would say it is now has a perfect feel, When its cold its still a bit tight but once its warmed though its superb, Before changing the oil it was very nice when cold but when warmed up it got a bit tight and annoying so to me that meant oil was not working when hot as it should and although it should not be changed till quite a high milage/time period the oil i took out was very thin and very very black.
