I am a member of the Dutch alfaromeo156club.nl club.
I have a major problem with the 156 v6 24v q-system and i hope you can help me in our own club nobody can.
The Aisin gearbox did not engage R and if it did it made a ratling noise and was undrivable.
After diagnoses i came to the conclusion that my only option was to replace the gearbox, so i did.
Now after the repairs te engine runs smooth and you van hear the gearbox run but it won't make the driveshaft's turn around.
I believe that the ecu doesn't make the actual shift.
Now the gearboxlight on de dashboard flashes, i don't know the meaning of that flashing sign and i can't find it in any book or internet.
Only 12 of this model were sold in the Netherlands. So getting info really is almost inpossible. I've got the official workshop manual (alfa romeo) but it doesn't say anything about it.
Can you help me????
