first thing to check is the ATF level is good. Engine running, flat surface, the fluid should be level with the fill plug  :y

thats now done , level was fine

seems to do it between 3rd and 4th and before it drops out of gear it seems to stay in 3rd to long , goes past revs of were it normally changes for 3 - 4 seconds , then drops out of gear before about 2 seconds later changing into 4th and then it will behave itself for rest of day

Are you able to get any codes from it.

Being a 2.2 you'll need a code reader, as the pedal and paperclip trick won't work.

Where abouts are you ?

As some has previously said, first thing to check would be the fluid level as this can cause problems.
http://www.omegaowners.com/forum/YaBB.pl?num=1152783586

If that is at the correct level (and colour  ::)) then you could go on to check to see if there are any codes stored.

I'm only 25mls away from you and could bring my basic code reader over, to see what and if anything is being shown?.
PM me if you're interested

However, it may well need to get someone with more sophisticated code reading equipment to help out.  Ideally someone with a proper Tech2 as that's the daddy of them all  ::) .

ok ive had the codes read today

(http://img.photobucket.com/albums/v157/atherlon/img023b.jpg)

(http://img.photobucket.com/albums/v157/atherlon/img024a.jpg)
error codes found were -
 
p0340 - cam sensor
p1700 - service request via can
gearbox codes were -

p1792 - can recieves error
p0727 - can recieves error
p0730 - unknown code
they advised me to get firmware updated and i must say its altered the car so much , drives so much better , feels like a different car . only problem is gearbox is still playing up

this time it came up with car/spanner light and went into limp mod , error now is (if i remember correctly) gearbox over rev error - 900rmp to great ( i think its p0730)

i think this is just were 3rd gear is not changing and so is reving to much in that gear instead of changing gear but i really dont know

the garage tried to sell me a recon gearbox for almost £1200 lol , well that isnt going to happen

learnt to check out all my solenoids, always worth a check as they'll completely trip the box out?

being a 2.2 once you replace that cam sensor.


the gearbox will likely behave and the other codes will dissapear like magic  :y

the cam sensor on a 2.2 causes all sorts of grief, and brings on other non existant faults.  Change it and you will be sorted  :y

athers ... I don't know owt about the 4 pots .....  but the 0340 - cam sensor ... says to me that the speed signal to the ECUs may not be right at all times.

If the Engine ECU and the gearbox ECU are getting differing speed information this could well be the cause of the problem ???

My thoughts would be to sort the cam sesnor out and then see what difference you get. Cam sensor needs fixing anyway .....  :(


EDIT .... must type faster .. jimbob's beaten me ... again .. :(

Yep, agreed.  :y

I've seen all of these codes present, and autobox misbehaving. Cam sensor fixed the lot.

Doesnt amaze me   :'( ;D ;D ;D

Oh....and when you replace that sensor, dont try and saeve a few quid with a pattern / aftermarket one. Get Genuine from Vauxhall.  :y

I reckon that when the crank sensor on the V6 is on it's way out you get similar symptoms.

Once I change mine after Easter I should be able to confirm this.

Before you go buying a new cam sensor, just try unplugging it and cleaning the contacts with a bit of contact cleaning spray.  You have the same symptoms and codes I had and simply disconnecting the cam sensor and reconnecting it cleared the problem.  I was getting a P0340 every other day or so but I haven't had one for nearly two weeks now.

Post by: athers on 05 April 2011, 18:41:33
ok had cam sensor changed (plug was also broken  :'()

it hasnt faultered yet  :y but now that they put firmware version 10 on ecu and gearbox yesterday , the gearbox is "lumpy" as hell from cold , was so smooth before - except for the orignal fault . does anyone think this could be this new firmwares fault ??

Post by: Jimbob on 05 April 2011, 19:29:19
some gearbox programs run in 'keep it in low gear mode' for a minute or 2 to heat the atf faster, could it be that you are experiencing?

the upgrade is normally a massive improvement.

The car may also take a day or 2 to learn new values depending on what else they have done.

Post by: athers on 05 April 2011, 22:20:02
it might be that , as when i took it home from upgrade and engine was hot it was a different , in a good way , car
