ok - so I tackled this yesterday....

One warning - dont attempt this unless you are mechanically minded....
especially if the whole linkage arrangement inside the box - springs apart on you and you have to methodically work it out and try and try again to get it all back together right.....
You want that stick to feel exactly the way it was before you took it out/apart - with a reversing light this time....

Anyway couple of extra pics - I built the worn cam lobe up with epoxy as well.

Similar Area - but different problem - sorry to hijack....
Has anyone had a failing +/- on the PF (>2000) electronic boxes where the +/- gets to be a little hair trigger (more so on the plus(+) than the minus(-))?
I'm thinking I will need to pull the selector apart as we had to with the this reversing light issue and see if I can massage it back the other way.

???
eg: I have to push a full left to register a minus(-) as would be normal, but it only takes the slightest whisker of a touch to register a plus(+).
I think its getting worse and may possibly prevent me from going minus(-) 'cause sometimes lately, as soon as it flicks back from a left push minus(-) it can sometimes click itself back a plus(+) and end up back at the same gear.
