Hey all,

Not even had this car very long and ive got the airbag system failure -which doesnt really bother me.

But had to get her towed last night because of auto gearbox failure. I dropped into second from 3rd and beep beep its coming up and puts me straight into neutral.

Had this once at a friends house, but just left it 20 mins with the engine on and seemed fine. Wouldnt work this time though. Checked receipts and found in fed over 800 quid was spend on the SS gearbox at a fiat specialist in sutton-in-ashfield way. new pump, actuator, refurb, sensors the lot. So should this really be happening now? Should I contact them and say - the work hasnt even lasted?

It wont drive or go into gear at the moment, i dont have anyone with any diagnostics either which is garbage - im based in nottingham.

Any ideas? thanks all
 
find out how long ago the work was done if less than 12mths or whatever the warranty period was then they should sort the problem out it will depend on how long they warranted it for after the work

:yeahthat:

I assume the pump can still be heard running? Whats the level of the SS fluid in the reservoir?
 
Pump can he heard. Fluid is pretty much to the top, bar 2 cm?

HERES something odd though. I tried it this morning and tried that open the door 10 times and close it. It's fine, will drive, will go into gear... what the hell is going on?

The work was carried out at Alfa Tecnico in feb of this year. Included new SS pump, actuator and fluid...
 
So what could have happened here?! HELP

hey all, Selespeed again,

So I got towed home on Monday after auto gearbox failure, it went from 3rd into 2nd and then wouldnt go into gear no matter how many times I stopped and started the car. Pump was working etc no problems.

Tuesday morning - Car turns over fine, goes into gear fine, revs seem a little high for movement but I didnt dare drive her far.

Thurs morning, i decide to bite the bullet and drive it to work. 10 mins into driving - gearbox failure. I pull up, restart the engine - its fine again. I take it 40 meters to the next side street. Its starting to kick off while im turning around. Stalls on a hill and locks brakes etc. I keep trying to turn it on, get it on and moved so im not blocking traffic.

Get the laptop out and stick fiatecuscan on it. NO ERRORS aparent just a p1770 which is the accelerator pedal signal. Surely nothing to do with this.

Try to cut my loses, turn around and go home, Got stuck on the dual carriage way round about in 1st gear at light. I hear a rumble and BANG the loudest most aggresive stall from being still ive ever come accross. Nearly hit the car in front. Gearbox failure comes up again. At this point I have had enough and get it towed to alfa technio specialists.

What on earth is going on here. They said they drove it and couldnt get the gearbox to do it and it just just juddery. Put it on examiner - NOTHING whattt??? They recalibrated the clutch and box and said its driving fine, but will need a new clutch? New pump 2x actuator etc was done earlier in Feb this year - not by me, ive had this car 3 months.

I picked it up this morning, the judder is gone, but im scared driving it. Got it home, set me back another 80 quid. Aparently sub frame rear bushings are gone too and needs a right arm. So its not hitting Feb MOT. I do not have 1200 for a clutch, i really do not.

Can ANYONE shed some light on what might be happening here? and what are my options realistically. I dont think I want this stilo abarth anymore. its a 2002 model.

Thanks in advance!:mad:
 
Not all that clued up on the SS box but I'd assume the system relies on quite a few sensors from clutch/ brake/ accelerator pedals to know or predict what it has to do. If one of them sensors isn't working probably then the signal can make the the geabox ecu behave differently, perhaps?

If the clutch has been recalibrated on the ecu and they say the clutch also needs changed (also with MEP that the price is a bit high) then the ecu will need to be recalibrated again. If it's stopped the juddering then my advice would be to check out the accelerator fault, replacing it may be a worthwhile course of action.
 
1200 is steap then?

Do you think it is okay to drive? i really cant deal with getting it towed again!

Mark, I cant get that error code to come back up since I cleared it...
 
Since you have multiecuscan at your disposal what you could do is drive round in a small circuit close to your home with the software plugged in, there is an option to display multiple graphs in real time with different parameters displayed. If you do that and are able to replicated the problems you've been having then hopefully something will pop up on one of the graphs that would be out of the ordinary
 
okay,

Scanned on fiatecu on the engine instead got code P0704 - invalid signal

which is the clutch switch sensor apparently. Two other codes came up but im sure theyre from previous as its the boost thing and i replaced a dead ignition coil.

I cant clear them because its not the registered copy of the software so im a bit stuck. Do I get the sensor and try replacing it? Will this possibly solve the problem?

I didnt think a selespeed wiht auto clutch would have a clutch switch sensor, but im probably wrong. Is there a specific selespeed model for sensor too as I have seen these on ebay for about a tenner second hand.

Makes me think the fiat specialist didnt put it on examiner at all really if these codes are here and they found nothing but I still paid for 4 litres of oil and £35 quid for diagnostics...

Advice much appriciated. - Would it also need recalibrating after installing these and would the codes need to be cleared too?

Thanks.
 
The clutch switch is on top of the clutch pedal and is used to turn off the cruise control when changing gears. I assume your SS has cruise control but I didn't think they had clutch pedals let along switches? :s iirc from another thread the engine ecu adjust fueling relative to the clutch switch being pressed to make gearchanges smoother.

I wouldn't think you'd need to recalibrate the ecu, that's for changing the clutch itself I believe. And yeah you'll need to clear the code if you replace it, if it comes back on after replacing then there's something else going on...
 
It had clutch and gearbox re-calibration at the specialist.

Thats the thing.. there is no clutch so does this system even use that part? and where on earth would it go?! It does have CC but would this cause the problem to auto gearbox failure and stall?

What are the reprocusions of not clearing codes? Does it pick it up easier?

I'm not sure at all where to go with this...
 
The clutch switch on manual Stilos with cruise control is mounted at the top of the clutch pedal in the drivers footwell.

You could try clearing the codes, but make sure you take note of what they are (P.....) before you clear them so as you know if they come back that they're the same codes or not. If it comes back then I can only suggest changing the switch and see how that goes, as you said they're not expensive
 
This is the selespeed system, doesnt have a clutch pedal :-s

It wont let me clear the codes because it will only run in simulation mode, I dont have a registered copy urgh! So im a little stuck.
 
Im in Nottinghamshire, I dont know anyone with any diagnostics.

Would that sensor be the same whether selespeed or manual though? or would the sensor be different depending on the transmission?

Thanks,

I'm guessing, but probably different. A manual shouldn't have a need for one I'd have thought.
