I've read loads of threads on this and was hoping someone could give us some advice.
When I select 1st a clicking sound (normal when the gear engages) happens but it doesn't engage and goes straight into N. Doesn't go into R at all. If I push the gear stick up twice, it engages second gear and I drove off in second but it wouldn't do any other gear changes (up or down) so made it home at 20mph!
The resovoir seems to be at the right level and can't find any indication of leaking. The pump makes a positive sound (no different to 'pre-trouble') when the door opens.
It's obvious that Alfadiag is required but I don't have a laptop.
Does anyone have any clues as to where to go next?
