From your post #28, looking at the photo, the amount of cable showing is quite different from the photo in post #5.
The photo in post #5 was taken before we started attempting to adjust the cables as per the procedure, locking the selector and gearstick.
If we lock the selector and pull the cable so that it looks like the photo in post #5 the gearstick is locked in 2nd gear position, that is why we were looking towards perhaps something being wrong at the gearstick end.

The cables do not appear to be damaged and all brackets seem secure and solid . The cables do not seem to be giving the required range of movement to select certain gears even though we followed the adjustment procedure numerous times. The selector arm moves freely and appears to be able to select all gears. As catnip pointed out the amount of new cable showing post adjustment differs significantly from before we ever attempted adjustment. We cannot seem to pull the right hand ( arm rotation) cable any tighter when the tower and the gearstick are locked.
We will try again tomorrow.
Thank you for your patience.
