Gearbox ecu has detected a fault.  You really want to get this sorted before any (further?) damage occurs.

Hi, Had gearbox oil and solidnoid replaced and problem still exists
When accelerating in sport button mode, car will move into gears until the top gear is about to activate at appox 115mph. The management light comes up and its like the same condition as if the coil pack is faulty. The two coil packs have already been changed. If I stop and turn off ignition the fault clears and drive away as normal.
Any views or ideas would be welcome

Have you had the codes read?

[Broomies Mate]

As DG above has said - You need the codes from the TCM.  Without them, you are pissing into the wind.

Out of curiosity though;

What happens if you do the same run WITHOUT sport mode enabled?

If you are just doing a very long WOT run, Sport Mode will make absolutely no difference to performance at all.

Have had Bank 2 sensor changed ( error code P0403), and tried the sports button again. same issue again with top gear not being reached and then engine management light lights up. turn car off restart and problem cleared. 1 min later bank 2 sensor comes back again

P0403 is EGR fault. 

What light are you ACTUALLY seeing?   

You are aware, I hope, that top gear will not be engaged when in Sport mode (until you are about 130MPH)

Do you mean 0430? The sensor isn't the issue... The fact you changed it and still have the fault confirms this.

The 2.6 isn't exactly a performance engine either.

Which it doesn't have

Exactly..... and I wonder why OP has come here with a 'gearbox error' and states P0403.

I'll wager that because it's in Sports Mode, it won't change into top and giving pre-cat codes due to being strangled to death.... (although pre-cat codes are very common on the 2.6/3.2)

[Doctor Gollum]

Factory fitted , although given the apparent abuse the cats are probably shot.

A decent spanking every so often helps keep them clean, but the 2.6, whilst hardly a gutless dog, is no performance car. Also I wonder what we're not being told

Any recent work? Any mods?

Indeed.  OP states it will change into top at 115MPH.  It's been a few years since I owned an Omega, but it was closer to 130MPH.  However, OP states the EML comes on (at ~115MPH) so I'll hazard a guess that Sport Mode is deactivated???

High revs for a prolonged period of time could point to anything.  I know for fact that the pre-cat codes won't rein-in the power.... so there's something else going on here.

[Broomies Mate]

Without proper codes, we haven't got a clue. 

[ronnyd]

What is the OPs obsession with sport mode?   I never ever used it on my Omega. BUT, it was only a Desmond.

I assume this is an April Fool’s post. If not this idiot is doing 115mph on a road somewhere near you!
