I would question the correctness of the Comma data sheet that implies that AQ3 is compatible with both Dextron and 9979A4.

Thanks that's seems very expensive for 1L of oil, will have a look around see if I can find it at more reasonable price, the specification from what I can see is "9979A4"

same stuff but cheaper https://www.ebay.co.uk/itm/324989317747
No, that is not the specification, that is the part number for the official oil.

The system needs special oil - you can't put any old oil in unless you want further problems, it is a special hydraulic oil not a gearbox oil!

I called Comma today to double check about the actuator oil they said this is correct the AQ3 is the required product and equitant to 9979A4.

Today I managed to fill the actuator reservoir with oil the car went into gears and then stopped changing gears again noticed the reservoir empty, looks like I have a major leak somewhere. I will be towing this to the garage tomorrow for them to take a look once fixed going to get rid of this car never buying a ECG gearbox car again!

Best to get a proper automatic with torque converter or stick with a manual.

There's a high pressure pipe which wears / corrodes through, or the slave has burst in the bell housing. Surprised you cannot see oil everywhere!
