i am wondering if anyone can tell me if they have experienced problems with their geartronic or automatic gearbox because they have had a brake servo which has a hiss when the brakes are applied.
any feedback would be much appreciated
thanks in advance

Hey Les, did you get your tranny fixed? What was the problem?

hiya vegas,

havent done much with it the last few days. before i tie a rocket to it and send it off to the moon, i am checking things out to rule out problems before taking it to the stealer dealer.

my faith in garages are poor because i have read so much on these and other forums that even the dealers have got the diagnosis wrong, ending up in a very big bill for the owner and the problem still not solved.

i am not sure if my car will need to go to the dealers to get the codes reset. i believe i may of fixed the problem, a broken wire to the gearbox, but i dont know if the codes have to be reset to get it into normal mode again.

it is still stuck in limp home mode and i have not got a choice of forward gears.

any suggestions, my dtc tcm screen reads "checking" ???

Have you tried disconnecting the battery cable from the battery for at least 30 seconds? I hear this is supposed to clear some codes.

hiya vegas,

i have had the battery disconnected overnight and it is still storing the codes.

i think i am going to have to get the codes cleared by the stealer.
