My wife's Stilo MW JTD has developed a problem with the gear change. It's an 04/54 car 22k miles we've had it since new. In the last month or two the springing that returns the gear stick to the 3rd & 4th gear plane has gone and the change from 1st to 2nd, 2nd to 3rd and 3rd to 4th is getting stiffer. If you push the stick across to the left for 1st/2nd and let go, it just stays there. You have to actually pull it back across (with some resistance). If anyone has experienced this before and has an idea of what the cause / solution is, i'd be grateful and relieved.
