When I drive off from cold in my '96 Disco with 94k miles, it's difficult to move the gear-stick between gears. As the engine warms up the gear-stick becomes easier to move but then there's a slight crunching of gears as I change. Is this because the synchromesh baulk rings have worn (doesn't seem likely at 94k and with thorough service history) or could the gearbox oil be low or need changing - are there additives which can help? (The clutch appears to be fine - it disengages at the beginning of pressing it and not near the floor.) Any thoughts or ideas gratefully received.
