VW Polo diesel 2003 TDI model - may fit other VW related models ?

Have a used gearbox for sale, as ended up reconditioning my own gearbox. Was told by mechanic does not work in 1st gear, however may be of interest to someone who can fix this. Gearbox was for a VW Polo diesel 2003 TDI model. Ideally pickup from home or local delivery within Coventry may be arranged. Please call if interested.
