R400D (2008), 6-speed box, 48K miles.
Something odd happened with the gearchange during the 30-mile trip to my MOT yesterday.
When I went to change down from 6th to 5th, the gearlever became very reluctant to move, and when I pressed on the lever, I could feel (hear, even) what seemed like poorly meshing gear teeth. It was as if I was attempting to make a poorly-synchronised clutchless change.
After a couple of moments, I succeeded in changing down, and further downchanges (5th to 4th and so on) were ok. Up-changes were as normal. The same problem occurred just once more during the outward journey.
Nothing untoward happened on my return journey, with all up and down changes silky smooth as usual.
The box is the original, has been faultless since new, and hasn't been reconditioned in any way. I've yet to check the oil level, but there are no leaks and the car was serviced by Millwoods 350 miles ago.
Could there be a problem of some sort with the synchro mechanism? And if so, why would the box behave impeccably on the return journey?
Any thoughts, chaps?
