    Default Issue selecting gears

    Hi All,
    Suddenly I'm having trouble selecting gears when the car has warmed up. If I let it cool down for a few hours all seems ok then issues again when it's warmed up again. Anyone any ideas I'm having the brake and clutch fluid changed on Thursday to see if that helps at all
    T.I.A.

    they have been known to go thru clutches quite quickly pal , is the clutch under warranty ( 2 years on some kits )

    describe the issue better... based on temperature related info its oil level or quality thats the problem. They are undefiled from the factory and even after 23k miles when i changed mine i could feel the improvement in the gear changes

    Mine had a very “tight” gearbox when I got it, especially when hot. New trans oil sorted it, so it does sound like that is your problem. Are you sure they have put enough in? Anyway - should get it looked at ASAP.

    agree with the above , not something to ignore ! on the point of fluid changes , does the siggy have a separate diff or does the gearbox feed it all ??

    Gearbox -> haldex -> rear diff... all have their own fluids and never the twain shall meet as haldex and diff fluid are very different and they are only separated by a seal, if they mix, you loose the diff.

    No separate front diff though - it is integrated into the tranny

    dont forget the transfer box as well... so thats 4 in total to watch out for.... only issues with the main gearbox though will cause selection problems
