Thanks to all re your advice. Following the comments re the selector jamming in neutral I have fiddled with this and Can now move the gear lever into reverse and first ie the one rod is now operating successfully but not the other (2 an 3rd gear)This movement from neutral to a gear is only achievable when the clutch is depressed so looks to me the clutch is not stuck. However although the gear lever gets into gear ok and the one presently working selector moves through to the gearbox the car stays in neutral .I should be able to get the other gears working with a bit more fiddling but cant understand why the car remains in neutral after appearing to select a gear Any ideas?
