Dont VX recommend a fluid change every 70,000 miles, i seem to remember seeing this somewhere.

It is in the OOF recommended service intervals 60k iirc. Vauxhall say the box is sealed for life, bless them.

In 'ere.

...and I remember wrongly.

Ok question time before I go and spend 50 squid on 2 gallon on ATF and a can of brake cleaner.

My new shed has been neglected for the last 2 years.
Engine oil was like tar but now sorted.
Gearbox is very reluctant to change up when the oil is cold.
Also it had a p1700 code which seems to have disapeared over the last 300 miles of my use.
Ode meter says 125 K

Do I drop the gearbox sump and do a total oil change and clean the filters out while i'm in there OR do I just top it up with fresh ATF and see how it runs ?

Never had a auto box before so this is a bit of a learning curve.

Also do I need a gaskit for the sump plate or is it a case of silicon ?

You can't change "all" the ATF by just dropping the sumps/filters, only about 1/2 gets removed as the torque convertor and cooling pipes are still full. actually emptying the system takes a quite a bit of faffing I believe !!

I did the "sump drop change" on mine at 85000, as its use for towing a lot .. and I'm very pleased with the result... changes were smoother, quieter and seemed to be earlier as well .. but that might be wishful thinking !!

A favoured method of changing the ATF on Merecedes forum iirc is to disconnect the outlet pipe from the transcooler and put the end into a suitable container.Then,start the engine and pump new ATF into the transmission.Job is complete when new ATF starts appearing in the container,rather like bleeding brake fluid.
I wonder if thres any reason this cant be done with the Omega autobox ? 

TG,if the car has been a tad neglected and the box is a bit grumpy I would change the ATF personally.
Iirc there is a gasket,but its fine to use sealant when replacing the sumps.

New gaskets and filter are about £35 from here http://www.jpat.co.uk/

Change it. That's twice the recommended mileage.
I prefer gaskets myself, but an instant gasket goo will do fine.

I know you don't mean silicon btw, but just to be sure, silicon is a no no.
Sealing the scuttle up maybe, but other than that, no. Just no

Indeed. Scuttle drain. Exactly that.

[TheBoy]

I'd chnage it.

Note, the TCM holds 1st gear longer when cold, to heat the cats up faster. ECO crap for the tree hugging hippies who really are a waste of valuable oxygen.

thats the method i use,works very well but uses a fair bit of atf

[Vamps]

I had a full oil and filter change on the Jeep, Merc Autobox, and noticed an improvement in gear change time and smoothness......

If its unknown, I think I'd like to have the sump off anyway, check and clean the magnet, and search for bits of thrust washer....

[feeutfo]

Yes I'd like the sumps off, but I'd also like to get ALL the atf out too
