Hi all,
I have had similar problem when suddenly no power in reverse.
Looked it up and saw all sort of pull apart and major adjustments to hydraulics and gear box.
Well it turned out that the nut on the end of the rod attached to the pedal has come off.
The movements of the lever had no pull power to move it in the transmission as it was moving on its on spot and not pushing or pulling anything,
There is a pivoting point in this assembly that has been worn out and poped off.
I temporarily put a cable tie to get out of that pickle and ordered a new part the part is K1122-42080 ROD END,5/16-24UNF. AUS$18-00
]The damaged part:

The new part:

All is good now same forward as reverse no transmission work required.
Just got to make sure it is firm and not loosing that nut again.
Cheers,
Ben
