Hi guys, new to this. i have a 2005 stilo 1.6 16v active sport (xbox edition). this car as only done 30k miles and as developed a noisy gearbox. at speed its a general groan but at very low speed it sounds like a chip fork in your bike spokes. it seems to be in all gears. i have changed the gearbox oil but no improvement. any ideas, please dont tell me new gearbox
