    Hi guys,

    Can somebody give me some advice on my girlfriends corsa, The S light on the dashboard keeps flashing, and the car will only drive in 3rd gear (i guess), This is not all the time, it can go a couple of days without doing it...

    Works fine trying to change manually, so its not a mechanical fault..

    I am very mechanically minded, but know very little about Cora's, normally work on truck's / busses etc...

    Hopefully somebody has had the same problem, and was able to sort it??

    Any suggestions welcome..

    Thanks.
    Gav.

    If you've checked the fluid level then the next most likely thing is the selector switch on top of the gearbox. Do a search on here for the stripdown and fix.

    If its not either of those two then you'll need to get the codes read.

    The light is indicating it's gone into limp home mode. Needs the fault code(s) reading out to establish what's put it on.

    It could be something as simple as requiring an oil change, or a faulty selector switch.

    I would get the fault code(s) read out first as it's not always the selector switch at fault. Why bother going to the trouble of stripping it down when it might not be the cause of the problem?

    Thanks for the advice guys, So far i have stripped down the gear selector switch, built it back up etc and re-fitted.. I thought i had cleared the problem but about 1hr later light came back on, next i will drain the fluid whole 7 litres of it, and top back up, as it does look & smell burnt could be the problem..

    I will keep you informed of the outcome..

    Thanks.
    Gav.

    You'll probably only get around 3.5 litres out as the rest is held in the torque converter and can't be changed.

    Thought it was only about 3.5 litres, 7 seemed too much for a small box, its only 11 litres to fill a bus gearbox.... lol...

    If the problem is not sorted after an oil change i will get the car looked at, i took the switch apart again and checked the components at work, all of them worked correctly, hopefully its some think simple like an oil change??

    Thanks.
    Gav.

    Someone has just posted something similar on another forum - turned out to be the fuse for the gearbox ECU (in the fusebox) had blown.

    Might be worth checking it (with a meter - not visually) to see if you're that lucky :ROFLMAO:
