In my experience they'll not be the least interested. I had the same kind of symptoms on my 3.2, but it only happened last summer after prolonged high speed use, was better with fluid topped up, but still happened occassionally.  I bought new filter and seals to change the gearbox oil, but procrastination and the need to do the cam belt and front brakes have taken priority.

I would try to find someone with Tech2 who knows how to use it (either an enthusiast or an independent technician)

I can read the codes and live data for the gearbox in my 3.2 and my 2.6 using the "scanmyopel" app on my Android phone with a 15 bluetooth adapter. I don't know if that would work on your 3.0 :-\

One of the OOF admins was based in Scotland and was able to offer Tech2 services but I haven't seen him posting for a while - don't know if he still has his Tech2  :-\

Hotel21 in Fife has a Tech2, IIRC.

First things first, though, might be worth checking that the gearbox ECU fuse is OK, as, if the gearbox ECU has lost power, then it won't respond to a code reader!

Well worth checking the gearbox fluid level whenever there are problems, as said.

Also, make sure the 3 round connectors behind the battery are securely fastened, and the connectors where the loom enters the gearbox.

Beyond that, codes from the gearbox ECU would tell us what it's not ahappy about.

 Dont know if this is relavent on an Omega, but have you changed your HT leads recently?
On the Senator, if a cheaper set of HT leads were fitted, they upset the gearbox ECU and caused it to go into limp mode.
High quality leads sorted it out

Not sure on the number on a PFL, but there's just the one fuse that powers all the gearbox electronics. :y

Fuse 9 failure results in full gearbox limp, and "Auto Gearbox" on MID.  Defo worth checking, it won't be the first one I've seen blown.

I got a new coil pack and leads fitted about a week before it started playing up
