Well can get 1 to 5, a bit stiff but then no oil in the box etc....
Have the selector shaft rotated clockwise like it says but seems that the reverse gear is not pulled in to the mesh properly, am gona take it apart (not fully gasketed up any way) and try again, but am happy that I can get teh rest of it all correct!!
I note in a diagram I have it shows a spring under the selector shaft...was no spring in mine or is that one of the difference between 4 and 5 speed?
