Cannot select 1st 2nd or reverse will not engage linkages all working but one of the selectors on the gearbox is loose and doesn't lock into position when moved .

any thoughts?

Sounds like an internal gearbox issue.
It's probably best to simply replace it with a second hand one. Hyundai Ioniq 5 Ultimate. The family car.

Been informed its a pin/rivet thats snapped on one of the gear selector swivel arms located on the gearbox
a common problem with age
The arm moves but the shaft doesn't and a few spots of weld is the cure.
Got to remove the air intake box to gain access . will try today to repair

Checked this morning found one of my selector rods was turning but the shaft wasn't. Less than 1 hours work to sort with a few spots of weld to fix the lever arm to the shaft . Tested and all good

Phew! - well done - that goodness you find the fault - it could have got very expensive Jules

Well done. That's more involved than most owners would be prepared to go. Top marks.  Hyundai Ioniq 5 Ultimate. The family car.

Yes
i was looking to upload a short video to show the arm turning and the shaft stationary?
also my manual gear change is tighter and feels refreshed

you tube Short to show worn selector . (Copy and paste into You tube)

I presume its splined and the splines have corroded and worn away Jules

I suspect it was a shrink fit. my PC is slightly to the right of Genghis
