Bit of a long shot, but you never know! My gearbox is whining like a good un....was like this when I bought the van, and for all I know has been like this for years and may well continue in this state for many more.... But it's annoying! I've either got to have it rebuilt, which will mean the bus off the road for a fair while, or replace it. If anyone has a box sat in a corner doing nothing I can give it a good home! I know what these fetch, and expect to pay a fair price (I have the stick ready to bite down on...) Here's hoping.....!
