could you please provide a link to this,

preferably from this forum..
so it's there in months to come ,
unlike photbucket , etc

thanks,
Charlie

Here is the link for Grande Punto Elearn. It has some very interesting reading. If you want I can also give you some more information on how the dualogic works. I just need to know which type you have, CFC300 or CFC328.

Do you happen to have an english copy of the pdf manual? the eLearn does not contain much about the selespeed.

I may have isolated the issue with the transmission in my GP. The automatic transmission fluid is always below minimum level; when I top it up to normal level, it leaks (through the pipe below) and again goes below the required level. The leak amount is always similar to the amount I top up, around 30-50mL. I'm trying to isolate the function of the pipe and potential replacement.

The car operates fine when in gear, but has a delay when switching from N to 1 (2-4 seconds).

I have the Fiat-500-training manual. On page 156 the describe the 5 speed Transmission in detail. That leak look like it is coming from the low pressure return pipe.

I had a better look at the picture, the pipe that you highlighted seems to be an electrical wire and the fluid seems to be leaking from somewhere else on to the wire.

Does it loose fluid even without the electric pump priming the system? The fluid enters the electric motor at the bottom of the tank, leaves through the metal high pressure pipe to the accumulator which is located on the solenoid unit and returns to the tank at the top through the rubber hose.

Still no luck with this, changing gear from R,N->1 still requires a few seconds delay.

Regarding the leak in the automatic transmission fluid. This would happen only when I topped it up, maybe the system would overflow and leak only the amount which I topped up? The system seems stable

I have now managed to connect multi ECU.

The good – the hydraulic pressure seems to vary between 40bar and 48bar. It sustains 4-5 gear before falling to 40 bar before it jumps to around 48bar again.

The bad (?) – I have one error showing for the selespeed and this is "P1772 GEARSHIFT LEVER SWITCHES (ONE OF 4)". Switch contacts stuck. The fault is present now. Take appropriate action to fix this sensor fault. Dashboard warning light was activated for this fault. "

A translation from another forum says "In order to replace the gear lever / gear selector group you have to remove the tunnel between seats, unscrew 6 Torx screws keeping the gear selector and disconnect the electrical connection (a little tricky, pay attention, you need to push the bottom rugged surface to release it)."

There is a youtube video on a related procedure for changing the gear linkage cable but I'm unsure this is related as it refers to another model. Dualogic manual and eLearn conveniently don't have much information on the selespeed gearbox.

Anyone with a similar issue?

EDIT – I see there are 'side-to-side' and 'forward-backward' would these refer to the directions of the stick?

Only guessing here !

side to side and forward/backward actualy refers to the stick movement (almost 99% sure)
The 4 position switches should be located at bottom of the gear stick OR on the gearbox itself (50/50)

@ Tonico: do you have the 500 manual in PDF ? If so could you upload it ??

You can try to check the transmission selector in Multiecuscan. Go to parameters and select the A/T transmission position lever, Gear engaged and Gear selected check boxes. See if the A/T transmission position lever, correspond with the other two.

The gear selector use hall sensors to determine the selected position on the gear lever.

Their is one hall sensor for each of the positions on the selector. A magnet is attached to to gear shift lever and creates and magnetic field which excites the sensors. This signal is then coded and sent to the gearbox.

I have tried to upload the file to the Fiat 500 download section.It is being reviewed.

Thanks for the precise description and the upload Tonico !!

I had a look to check this – the position lever does indeed correspond with the gear engaged and gear selected checkboxes – but the specific error was not occurring at the time, it's quite intermittent.

I think it must be either a hall sensor error or a gear linkage cable error corresponding to the side-to-side movement of the lever. Changing from N->R or vica versa (i.e. vertical movement) never makes a problem. It's only when the lever moves from R or N to 1st gear (lateral movement) that I have the delay in engaging the gear.

Do you have any manuals related to these two parts? I have the eLearn and the dualogic manual but both don't mention any servicing procedures. Another post advises to check the gear selector unit connections checked but not sure how to access them.

Unfortunately I don´t have any manuals for the gear selector. Elearn has nothing regarding the dualogic. It looks like fiat made supplementary documents for the dualogic. The training manual I do have with the most detail on how to remove the parts is for the CFC300 M20 6 speed gearbox. But even this one does not show how to remove the selector.

To remove the gear selector should be very easy.

Look at elearn to see how to remove the centre console ( i can remove it in 3 minutes)




Once that is out you should see the selector (like in the photo below)it looks like it is only held in place with 4 screws.


Disconnect the battery negative then unplug the conector on the gear selector.

Their are no cable (only the manual cars have 2 cables) the single are sent via electric wires.

Request for a gear change or mode selection using a specially designed multi-stable electro mechanical lever with three stable positions (NEUTRAL, REVERSE and TIP) and three unstable positions (UP, DOWN, AUTOMATIC/MANUAL)

By means of 4 signals that convert the electrical signals of the 10 Hall-effect sensors located inside the lever itself (the signals must be read by the control unit as analogue inputs for safety reasons).

Tonico, the link points to a manual (apparently) leva cambio...
Is it the same housing / fitting ?

Regards, Bernie

Bernievarian, you right I didn´t even notice. Here is the correct photo.

Better ! Anyway, fittings are identical ...

Regards, Bernie

I had the same issue over and over again.. on cold start.. took it to fiat and £1500 later... it's all working perfectly.. one thing still need to be fix is my gear lever switch which playing up according to Fiat... and again that would be £620 to do.. grrrr

Waow, what for did they charge £1500 ?

Regards, Bernie

They change the actuator as the pressure was low all the time and didn't hold the preserve too!

Right, so after still having the error (some 3 months later...) I decided to have a go at changing the gear lever stick in order to hopefully rectify the issue.

The logic behind this is that one of the sensors inside the stick has failed so a replacement should remedy this situation

The bad news – I wasn't able to remove the old gear stick. The base of it is hidden below a metallic cover, of which there is no clear indication how it is removed.

The good news – Even without completely removing the old one, the replacement stick box is functional. However, its hard to know if the issue is fixed as the error I was getting was intermittent.

So there we have it. I'm wondering – has anyone had any experience in remove this metallic cover shown below?

Any comment here?

The eLEARN only goes as far as removing the coverings – no more detail on removing that metallic cover, annoyingly.
