A while back I posted a video of my car ('91 Rover Neon, but with a 1275) with an awful noise coming from it and seemingly not engaging the gears properly. I've taken my time getting the engine out and taking everything apart, bt now down to the gearbox, and the damage is obvious.
Basically the first cog inside the box, on both the first motion shaft and the lay shaft have broken or ground down teeth.

The rest of the cogs seem absolutely fine. I was wondering about simply replacing the cogs, but wanted to make sure the same thing wouldn't happen. The first motion shaft has a lot of back and forth motion in it (video below) - I'd put the case back on and the shaft itself is seated perfectly.
So I'm now thinking.... Do I replace the first motion shaft, and the cogs; or is this indicative of a bigger issue, and I'd be better off just getting a reconditioned unit?
Thanks, as always, in advance!
