V0A

Version 0A  and 0A in hex is 10.

A fluid change may help but, remember that the autobox has an adaptive setup to adjusts to your driving style....hence why after the 'nearly wales' the cars I had given a thrash will have been driving slightly differently and also why AA's car changes gear at 972 rpm....

Yeah right, you mean 9720 rpm

In sports mine changes up around 6600 - but it is running a little off so I am checking it this weekend

With the new software, it should change up at redline even in 'economy' program, if you foot is hard planted....

Does the box need to relearn one's driving style after a change of battery?
Mine appears to be behaving differently since the new battery last weekend

Should adapt very quickly.

What is the box doing? Misbehaving?  You have a tractor, so the original box is good for about 120 - 150k normally...

It must be catching this gearbox problem. I have just bought an Omega  2.2 CD 2002 petrol. And i have just spent a fortune trying to get it to run spot on. Re- gearbox i have had the same issues ,in a morning hangs on before changing up gears, paid for full gearbox service then i was told this is normal for this cars gearbox. Also sometimes if stuck in traffic, when i pull away  it sometimes wont change up until about 3000rpm then is fine again, although i have found it all depends where you have the throttle positioned. I have  had the car on diagnostic machine for gearbox check every thing is OK they say. Also on hills it cannot make up its mind what gear it wants to be in
                                     Plus can i ask if other 2.2 omega owners feel the same as myself, that they are let down by the tick over, it is not very smooth, plus the engine sounds agricultural for a top of the range luxury saloon. I have spent hundred's trying to sort this car out. New exhaust manifold (cracked) new diss pack and cam cover gasket's plus plugs. Cleaned every breather pipe out plus can eat your dinner off the throttle body. Again it has been on diagnostic machine for the engine this time, again  every thing is coming up as OK. I have owned other luxury cars or cars that cost the same as these when new, and it is not a patch on the Jaguar, BMW, or even the Maxima i have owned. It is a shame really as i will admit on the motorway it runs spot on, and the handling is excellent, So is the ride and comfort. It is just a pity its let down by the idle and the gearbox problems, regards bash

If the gearbox is misbehaving, it is likely mechanical.  Start by changing fluid first.  If it is just smoothness, v9 (or later) software helps.

2.2 idle isn't silky smooth like 6 cylinders engines, as its only 4 cylinder.  Saying that, its no worse than most 4 cylinder ones  :-/

And also remember, computer diagnostics are useless unless the user knows what it is saying, and can interperate the live data readings.

Cheers for the reply, i agree about the smoothness of the engine, i may be harsh comparing a 4 cylinder to a six, but i still think even compared to other manufacturers 4 cylinder engine's. The  Omega 2.2 litre is not as smooth or as quite . As for the fluid change, this was done with a filter change when i had the gearbox service done and the gearbox diagnostic check only a couple of weeks ago. The place that did the gearbox diagnostic check and service is classed as the best place for gearbox's in my area. It repairs and rebuilds  all the luxury ,and top of the range sports cars with all the most up to date diagnostics's available it even does the main dealer's gearbox problem's for them. Also the chap who does the engine diagnostics runs a rolling road tuning place . Sets up Rally and Track car's plus super car's, and as he says . The equipment has not shown any faults in the last ( i cannot remember) but so many starts, and he has even gone through the check with me showing the throttle position, drive by wire and all other parameters working just as they should. I will admit it is far better now the manifold and diss pack has been done. BUT from what i have read on the forum the gearbox has been a pain from day one in the Omega. RE- the 2,2 engine not a lot is posted on it, this is why i have asked for others with the same engine to comment Regards bash
PS i am not complaining about the smoothness of the gear change, it is just it seems to have a mind of its own on hills . Plus unlike other auto box's it does not seem to have set rev ranges for gear changes plus it is super sensitive to how much throttle you use, re one reply i cannot get my box to not change before red line, even when i have the peddle to the floor

The box, in economy (normal) mode is adaptive - its change points will vary based on your recent driving style.  Rag it around the lanes for a few miles, and you will notice it starts changing up higher, and down earlier.  Drive like grandad, and it will start changing up lower...   ...that is the design.

Later software does tend to improve the general drivability of the box, as GM develop it...  (in particular, the step v8 to v9 is a much better firware)

[bash]

Many thanks for the info , i will watch and see how it behaves in the next few days driving steady for a day then giving it some boot, will admit hardly ever put it into sports mode. Re- soft ware up grade is this an upgrade you buy and have fitted , or can my gearbox centre re programme the box using the most recent diagnostic equipment.

Mine does in sports mode   Floor it in sports mode and it doesnt change until it gets to red line

I know what you mean.....mines the same  :-?

[korum]

Hmmm maybe its something different in the 2.2's i hvae a 2002 cd auto and mines the same, when crawling along in traffic it cant decide what gear it wants and will clunk when you let go of the throttle.
Also when im travelling at around 45 and ive got the throttle just enough to keep that speed the box cant decide if it wants 4th or the lock down gear??

very enoying
