    sort of gear crunch??

    Hi all, cars just started doing this tonight on the way home from work. Its started making a crunching noise as you go into 3rd but its not hard to engage the gear it feels normal its like its just all of a sudden ran out of grease on the gear stick.

    nothing serious i hope any ideas??

    Hi.
    check the fluid for any leaks,

    switch the engine off then try selecting 3rd gear to test if it's still

    crunching, might be the clutch.

    shouldnt be the clutch as that would start crunching into 1st and 2nd before any other gears and all gears would be a bit stiff. It is most likely that it is a box fault, but before a gear selector gets condemned as said check for leaks as you may just be low on oil. Sometimes a change of oil does wonders for the box

    Thanks for the replys guys

    The cars recently been serviced so i would hope that the oils been checked and changed in the box. It doesn't crunch when the engines off or when its idling just when you change up or down to 3rd when driving, was thinking of adjusting the clutch see if that helps but i dont know how to go about it on this engine , my old corsa was easy enough as it could be done from looking in the engine bay is it the same with astras?

    if it is doing it going up and down the gears then I would bet that is a knacked syncro and cones on the 3rd 4th mechanism in the box

    most places won't check the gearbox level, mainly because its a pain in the ass, you can't adjust the clutch, its hydraulic. as said, it sounds like the syncro is on its way out.
