What a dork! - oh well sorted now. Although I must say the manual isn't clear... and it looks bloody awkward when fitted... Anyway, next problem.... the o/d has stopped working.. yes, it bloody has!
Took her for a spin in the sun and engaged o/d.. great, and then it dropped out of o/d. Got home and tested it... no 'click.' What should I check first? - power supply to solenoid I guess? - fuse is ok.
Oh, and the whirring noise is still there!!?!?!?[xx(] - what a waste of time that was!!! It only makes a noise when in neutral... so the clutch is dragging for some reason?!? - God knows why though!?
