Hi all i have a problem with my auto box
When auto box is cold i have some drive but when it gets warmer i end up with no drive
I have checked the atf level which is fine but is a very brown colour.
 autobox was changed for a recon about 18 months ago and has done about 24000 miles since omega is a 2.5 cdx /2000year
regards

Clint

do you get any drive if you manually shift to 1,2,3 ?

I'd take the selector switch and give that a good clean first. When you checked the ATF, was it to the level of the drain plug, on a level surface with the engine running?

[clint omega]

no drive at all when selecting different gears and when checking the atf it was warm with engine running and on level ground

Have you had any warning lights or messages on the display. Might be worth checking for any codes try paperclipping or pedal trick. Not sure which one for your car but there will be a link in the maintanence guides.

no warning messages nothing i will have a better look at it the weekend if it stops raining but any more advice would be grateful

I'm new here, and I;m a new owner of omega z22xe. I had a same problem with my automatic gear box, the atf color is brown because it's mixed with antifreeze or water from the engine cooler (radiator). I had a same problem with my omega and i had a new cooler but i'm suspisious that it wasn't the corect one because usualy omega b is under 1999 and my omega is 2003 (some people call it Omega c). i hope that somebody hwo understands let me know what type of cooler is from my omega 2.2 16 petrol 2003.

I reckon its the TC myself but it won't hurt to drain the fluid and replace it.

[sandune]

Yes, as said inan earlier post,drain the aft and refill.

[gasxxx]

I've done that, i've drained tha ATF and put a new. but my servicer is saying that the you have to change the cooler because it will mix it aging with antifreez.
thnx for rply.

Not sure when it changed but the autobox oil cooler was originally in one end tank of the radiator. To change it you need a complete new radiator. A new radiator costs about £200 from VX.

Later ones are just a length of pipe that wiggles around in front of the radiator so there isn't a risk of cross contamination.

I understand but my servicer told me that engins that runs on petrol doesn't have radiator inside the gearbox. the only cool the ATF in main engine cooler (radiator). only diesel vehicles has the radiator inside the gearbox. So I have to change the main engine radiator.

Yes, thats what I meant.

[Andy H]

I think Diesels have exactly the same.

For the Omega, there are no differences in the gearbox, diesel or petrol. Box is the same inside. ATF is always cooled in the rad
