Ford KA reverse gear problem?

This only happens in reverse, but when I try to select reverse it won't always let me select the gear. Also when I lift the clutch up a very horrible grinding sound appears when you don't put it into the gear properly. When this happens I always try to put it in properly but it still happens sometimes.

It is a 56 plate KA

Is it the gearbox, is it the clutch I don't know, but it is very annoying and inconvenient for me and other users of the road.

Hi so what do you expect from an old ford which has now got a very worn out gearbox. The age is something of an indicator now 8 years old the end of it's design life.

Trade it in. The original Ford KAs are crude by today's standards. Swap it for a nice reliable Asian built car.
