Zoom in on photo you can see it at front of assembly, left side of first pic.
7th pic on link is close up.
Ok. I think I will remove old one and see if I can see a part number, might not be today, but one night this week lol
Clear the codes
Try it for a bit
Read the codes
Try it till it fails

P1818 does not help much
The transmission control unit has asked for a change
It's failed mechanical, hydraulic or failed to register (sensor)

You've lost fluid. There are 2 areas the robot leaks from - the gear selector actuators (2 solenoids) and the clutch actuator. The clutch actuator will have have weepage around if it has been leaking. If the gear selector actuators are leaking, the leaking fluid builds up towards the gear position sensor at the front, and will show weepage.
Mine has weepage around the clutch actuator, but it's currently behaving itself.
It's interesting you can still change gear manually (up/down) when hot, which suggest the robot is working ok.

Fyi, Alfa odb demo app will show you fault codes too. I now have the paid version of this.
Some tests here
www.fiatforum.com
And in the PDF here first one
Section
Р1818 (A/B-III) Shifting Gears Control (24)
Gives some hints and a few possibilities
Unfortunately this code isn't particularly helpful. Its basically say something went wrong but don't know it does not know what

Hi koaler success someone had insulated the small thread that fits inside the battery tray with tape presumably to stop it rusting I took the tape off so I could get the bolt off then the gauge instantly went to 3/4 so thanks for your help

Looking at that photo, I am thinking is the green line on the actuator fluid reservoir the minimum or maximum level as I can't see any words on mine ?
I have taken it to be the maximum level with the unit depressurised, am I wrong ?

The dialogic has gone through quite a few different evolutions
Is this reservoir closed to yours
Should be at the min after the door been opened
It's on the top towards the front of the actuator
Click link in post 62 and look at photos to find gear position sensor.
I think your photo is clutch position sensor.
