    Default Help! 03 Signum 3.0CDTI - gearbox just went??

    Well i've had the Signum a week and about half an hour ago when i was out in it, whilst under medium acceleration the gearbox seems to have let go.

    Basically in 'D' there is a metallic noise but no forward movement, in reverse same metallic noise and no reverse movement. Car otherwise sounds fine - gearbox makes no noises in neutral or park. Engine running fine, no engine management lights on.

    There is no oil under the car which i hope is a good sign.

    I've phoned the AA and they'll be with my by about 2100 to recover it. Having it brought home in the meantime, as i dont know what to do with it.

    Anyone any experience with a problem like this? I guess the likely culprits are:-

    Gearbox failure
    Diff failure
    Driveshaft failure / snapped

    I'd appreciate any feedback at this stage as i'm now panicking over a looming massive bill!!

    It does point to the gearbox though. I very much doubt from what you have said that it is the driveshafts, and unlikely the diff". Is there enough gearbox oil in ?. I am not too conversant with the Autobox. But there was and may still be a bit of an issue where coolant gets into the autobox, whether this has happened to you will need to be investigated.
    How old is the car. Is it still under warranty from either VX or from where you bought it from.

    Topic suggests it is a 2003

    I suspect the torque has blown the gearbox
    As I posted a few weeks ago, I blew my first ever clutch, it just went with little notice and what appeared to be loads of bite point left too

    Equally, you are looking at some serious wallet opening to get the gearbox out

    Where did you get it?

    Have had it recovered and is now back at my house.

    The recovery people had a look and think the passenger side driveshaft is 'wrung'? Its moving about a fair bit and the noise seems to be coming from the end of it.

    They thus reckon a new driveshaft should solve it.

    My mechanic is coming up tomorrow so will get a definitive answer then.

    Fingers crossed!

    Oh - its an '03 car bought through a trade friend. I didnt pay a fortune for it, but equally i dont (cant) spend a fortune on it!

    Thanks for your help / support so far. Will keep you posted

    What in an auto? the autos have reduced torque over the manuals anyway!
    Now I need a turbo to keep up!

    Hence why the torque is reduced on the auto, the manual is at the limit, so the same issue is clearly going to affect the auto (if not worse from reports so far)

    The 5-speed autos had engine torque reduced to 258 ft/lbs (which is still slightly over what the gearbox is rated at) in order not to stress the AF-33 box. Later six-speeders can handle more torque I believe.

    It's weird that a driveshaft should fail on an auto, but I guess that torque is torque.

    The torque converter has died. Oill cooler/ heat exchanger (whatever you want to call it) has failed and you will have water in the box which will kill it

    Exactly the same happend to mine just over a month ago, its been stripped down and re-built, there are no re-conditioned gearboxes available and even Vauxhall don't have any, was looking at a replacement box instead of a re-build but its not an option.

    Unfortunately you are looking at the wrong end of £2.5k at best to get it fixed

    To confirm its not the drive shafts, if you go out now when its cold you will be able to drive a few yards before it goes again
