I had a look at a 73 bus today. It had issues with going into 2nd from 1st or 3rd, and the clutch point is a lot further out than I would like. Could these be linked? Is this a gearbox or clutch about to shit itself? It is a 3 rib gearbox with a 2.0L. If it is a gearbox issue, what will a replacement cost me?
