Ford Focus MK3 manual gear change issue

[mikeyr]

Any thoughts on a probable cause?

6 speed manual, 1.0 ecoboost car, 2014, 90k, recent service and wetbelt change.

I've only owned for couple of weeks. And until today it's been spot on and gear change nice and positive. But suddenly today, on a twenty minute drive, the gear changing is intermittent, it can be buttery smooth or can feel like the gearlever is out of alignment, banging into resistance when changing gear. Any gear can become completely blocked out and take a couple of seconds to happily slot back into place. Or, fifty percent of the time, the gear change is totally fine, very smooth.

The clutch seems okay to me, at least my foot isn't detecting any discernible difference, unless this is symptomatic of a clutch cable issue that I wouldn't be able to detect?

Thoughts on likely culprits?

Ps no obvious noises whilst driving and gear lever stays in place, no wobbling etc, it's only intermittently on an actual gear change where I might end up hunting around for a gear!

Oh, and parked up at home with engine off and clutch not depressed I can generally move through the gears smoothly and quickly

Its most likely hydraulic not cable so could be a failing master/slave cylinder.

I should add that the last bit of travel when releasing the clutch feels a little bit slow, like it's a different speed the pedal is coming up at.
