Hi Callaghan82 where did you get your gearbox refurbed for only £450?, that sounds very cheap when you consider the bearings, labour to take the box out and refit, and not forgetting the new oil, was it a Indie AR specialist or a local garage ?,
What miles did yours start going at ?, mine is making a slight whining noise in high gears at just over 90k, if you got the bearings changed for £450 seems a bargain.
Autolusso offer a gearbox exchange with 12 months warranty for over a grand depending what is damaged in your box which I thought was reasonable considering labour to take a box out and in.
I also figure if the box is coming out when I do mine I will also change the clutch at the same time, so both are done.
Will be interested in knowing who did your work though.
