my car (omega 2.2 auto on a 52 plate) has started very occasionally at slow speeds (under about 10mph) dropping into nutural for a second and then changes gears as per normal

any help much appriciated

[tunnie]

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

[mkirky]

Yes check fluid level first 

[athers]

Yes check fluid level first 

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.

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  .

thanks for the offer butas i live in shrewsbury i will take it into four crosses garage bicton , they are an authorised vauxhall garage (i wouldnt take anything to greenhous!!!) and will let you know what the error code(s) are asap

thanks everyone for all the help so far 

[athers]

ok ive had the codes read today




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

[cannonfodder]

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

[Jimbob]

being a 2.2 once you replace that cam sensor.


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

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 

[Entwood]

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. 

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

meny thanks , you have all given me a bit more hope 

will get cam sensor replaced asap

[albitz]

It amazes me that a Vauxhall dealer didnt know this.
