Technical dualogic selespeed pump fluid

Hi Stu,

too bad you SIL's mate didn't knew exactly what he was doing ...

In theory, the motor should have had a current peak that would have blown the protection fuse, OR it overheated and finally cuts the winding or shorted it to ground.
You really need to get the pump out of the car, drain it of any oil, disassemble it from the motor and see if it still rotates freely. While you have the motor off the assembly, connect it to a battery or 12VDC power-supply THRU A LIGHT BULB (this is to limit the current in case of internal shortcut): if the motor start spinning your're safe to reassemble the pump & motor and check again for a short time (there is no oil inside the pump !). If still ok, reassemble everything, fill the reservoir with new selespeed fluid and perform the bleeding/kiss point procedure. Do not forget you have to depressurize the accumulator as well to drain off as much as 'bad mix' as possible.
If the motor alone is not spinning, open it and check what went wrong, but I'm afraid it won't just be the brushes (unless maybe the old motor). You won't find them @ Fiat stealer nor on line (euro part or so), but a good hardware store will probably have what you need ...

Just reading your last post once more: yes there are two fluids in the system: the 'thick' (tutela) one is for the gearbox itself (like a manual one), to lubricate the gears and differential; the second one is hydraulic fluid (Selespeed) that's used by the robot to move the actuators that drive the clutch and the gear lever instead of the human interface (You) ...

Tell us how you get on !!

Edit: Ideally the entire system should be disassembled / cleaned, it's NOT that difficult but you have to be very meticulous ...

BRs, Bernie

Ive stripped the pump out, just adding pictures to try and make sense of things.

Original pump on car that fail, after trying to start with low battery, cold snap, kept blowing fuses afterwards before it gave up the ghost.

replacement worked, for 15 minute test drive, next day wouldn't get gears properly till it stopped trying to get gears (this would have been topped off with gearbox oil)

The original and replacement pump are different models as in photo's, was told that just swapping the head over would fix the problems, I've opened the head and it seems to be working as it should, rotation of gears.

I've tried power directly to pumps, both not working, I checked ohms again, both have different reading using 20K ohms settings, as in photos. I don't know what it should be reading

I know I now have to bleed the complete system before I do anything, I can't get the fluid tank off, as not sure if it pulls off, as I've struggled or its got a clip I cant see, also where do I have to drain the rest of the systems down.

I can't find drawing or tec that is detailed enough to help, like I say I'm not a mechanic, so this is all new to me.

would the different motor on the pump make all the difference? as it did work when first installed.

sorry its so long winded but I'm trying to start from the beginning.

cheers stu

Dualogic transmission fluid initial fill must be performed in two steps:

- fill to the top
- open driver's door: the pump will prime and partially empty the reservoir
- adjust the fluid level to the MAX line: done !

If initial fill wasn't done like this, there is a possibility that fluid level will get low enough so the pump can't reach the correct pressure ...

Hi
When you say fill to the top does that mean fill the entire reservoir all the way upto the cap and then top up to the fill point max level

Does this include clutch bleed somewhere in this instruction

Why would I only get 3 bar and no more

Ran the pump manually fluid just sat there even thigh pump is fine

I removed accumulator didn't depresserize and it was empty
