Title: 99T 3.0 Elite Estate. Clunky Gear Change.
Post by: Paul T. on 22 December 2009, 03:07:14

Hi Everyone,

Forgive me if this is posted in the wrong section.

The box on my 3.0 elite sometimes changes gears with a thud.
The box can be fine for a week and then misbehave and then go into limp mode.

If I turn off the car and re-start all is usually well again.

My local VX dealer fitted a new switch £350 but the problem remained so the old switch was put back again.

I've had the car since a year old (17,000 miles) and have full VX history. The car now has 94,000 miles.

I may well sell the car but I don't think I could get a realistic price with this fault present.

Would it be worth paying to have the fault fixed in relation to the price I could expect to sell for?

Any ideas on how to fix and how much it would cost would be much appreciated.

Thanks,

Paul.

Could just be the box wants an oil (Atf) top up

could possibly be the thrust washer....box off to change.

Check the fluid level first ;)

Thanks Jimbob and Elite Pete.

I'll be pretty upset if the atf is low because the car has full VX history apart from the last service carried out by a local indy.

Is it easy to check and top-up the fluid?

Many Thanks,

Paul.

VX will NEVER touch the autobox in any service, designed as 'sealed' unit.

there is a level plug on the side of the box sump, no dipstick unfortunately.

the correct level is the plug, with the car flat, and running, so not the easiest to check, and you need fluid to add really....


when i do mine, I jack the (running) car up, fill to the plug, then lower to flat, some will run out as Ive filled at an angle, then jack up again and replace the plug.

Many Thanks Jimbob.

I'll try and get someone to have a look at this.



Isn't there a "Thank You" button on the forum?

Cheers,

Paul.

Even though its supposed to be a sealed unit at 94000 miles I would change the gearbox oil and filter anyway :y

If I changed the fluid, does anyone know how much the gearbox holds?

I have a pela style pump and could suck out the atf and then replenish.

Thanks,

Paul.

No, you need to drop both the sumps, remove/clean then replace the filter, check front sump for 'bit's of plastic. About 7 litres of new Dexron 3 (it holds more but not all will come out)
You said a 'thud', was this between 2nd & 3rd, ie after the revs 'flare' then 'thud' ?

Spot on about the thud between 2nd and 3rd gears.


Thanks for the atf product info Richard.

If you are buying ATF, most of us join OPIE oils where we get a club discount (see parts for sale section)

the fluid of choice is Fuchs Titan 4000  :y

Many Thanks Jimbob.

Does anyone have any ideas on the labour time/cost of the ATF change?

Can anyone recommend someone to do this job, would anyone on the forum be interested?

Many Thanks

Paul.

VX will charge about £70 (labour only)  to change ATF but make sure you get a fixed price as they do not do this job very often and sometimes struggle getting the sump back for some reason. Change filter as well. You will find various prices on here - VX even on trade club is a little expensive - but may be the best option if you need to do job quickly. VX will only drop out old ATF that is immediately within 2 sump pans - so replacement will be around 5L to 6L.

Obviously if you can be there when they check level and it is low you may get away with top up. Just had to do mine at almost 90000.

If the 'thud' is between 2rd &3rd as you agree, you could well require a new '2nd to 3rd solenoid'.
I had the same type of problem even after replacing the ATF and cleaning the filter, replacing the solenoid sorted the problem - many thanks to Forum members.
Omega's are excellent cars, well worth taking the time to understand them.

A 'forum member' sent me a 'used' solenoid for free, many thanks  :y  to buy from GM they are about £80.
If you are able to drop the large 'auto' sump then remove the filter, the solenoid is the one close to the centre line of the gear box, easy to replace.
It is a design fault of a other wise excellent auto box.
If you want a photo of the auto box and solenoid send me a PM with your email address.
