2004 L&K 130 6 speed. 2 weeks ago lost 1st & 2nd gear with no warning at all-no noise or anything. Main dealer changed 1st & 2nd selector shaft . Car ok for a few miles then difficult, sometimes impossib;e to select first gear. Now telling me that gearbox casing is worn? Car bought new, has done 100k with no other probs apart from normal maintenance-never been thrashed-still on original brake pads. Always done my own maintenance but unable to do so at the moment due to recent surgery. I suspect I am being hoodwinked somewhere, anyone else had or heard of "gearbox casing wear" with no previous symptons or noises etc. By the way new casing is £750 without labour.

TIA kevin

Never heard of it, plenty on here running the 6 speed with much higher mileage without any problem. Perhaps when they replaced the selector shaft they put it back together wrong causing parts to wear against the housing inside the box. In normal use there is plenty of clearance inside the box, or the original failure of 1st and 2nd caused gears or similar to rub against the inside of the box.

You could get a whole gearbox cheaper from a breakers yard, a lot cheaper.

I've heard of casing wear on a reduction box, but that was traced to an assembly error.
