Am looking for thoughts on what may be a related problem with a "new" gearbox.
Back in February, our Bongo (Seymour) started showing symptoms of gearbox trouble after a drive from Cornwall to Lincolnshire and back, so we took him to a local(ish) garage where after about a month's worth of investigations and, presumably, mechanicking we got him back on the road again. For about 100 yards!!!! He stalled and wouldn't re-start so had to go back to the garage. My husband reckoned it might be the torque convertor so ordered a gearbox off eBay and had it delivered to the garage. Another month or so and the new gear box was fitted and Seymour was returned to us.
We had a hell of a job getting him started, and on driving there is an awful whining noise. Does anyone know whether the two could be connected? The battery isn't flat, and the glow plugs seem to be OK so that isn't likely to be an issue with the starting. As for the whining, I have never heard a Bongo whine before and I never wish to again.
We will, of course, get Phil the mechanic to sort it out if it's not straightforward, but he's had to lay off his staff and is shutting up shop for a bit. Any easy fixes or things to look for? Of course the eBay gearbox might be faulty, but that's always an unknown quantity until it's fitted and you drive it. I haven't driven far in him, but my husband went out for about 20 miles yesterday and says he's flying.
If none of this makes sense, I apologise. I have limited mechanical knowledge (limited to maintaining a 2 stroke motorbike I had almost 40 years ago!!)
