i think u have a clutch cable on this model so try adjusting ur clutch cable up a couple of turns! its situated on top of the gear box. (be careful not to adjust it too much or ur clutch might slip) if the vehicle is quite high mileage have u changed the gear oil as this will also aid ur gear change!(make sure u use the correct gear oil ur local motorfactor will help u).if its only crunchin in these gears it well may be ur syncros on those paticular gears ,if u can change gear better with a slow gear change it usually is ur gear syncros! remedy 1 thicker gear oil , 2, a gearbox additive from ur local motorfactor(its usually molybdenum disulfide grease), 3, a reconditioned g/box!
