2006 clio 1.5 gearbox failure

Car is a 2006 clio dci 1.5 van, so still the earlier shape.

Was driving perfectly until recently when the gearbox started making a awful clunking noise when driving, makes the car impossible to drive.



I have been looking into getting a gearbox for it and it turns it the gearbox used is quite rare, the type is jh3145.

My question is, is it worthwhile looking into gettingthe box repaired or are there any more common gearbox types that would fit instead?



Thanks
