Why is there no drain plug??  :-/  and could the sump be drilled and a sump plug fitted?? 

Because GM reckon it's sealed for life.

And, yes, I've heard of others putting a plug in but only really worth it if you're keeping the car for another 60k.

Personally, I can't wait til I have the pennies for the last piece in my auto to manual conversion kit.

Actually... did the auto box on the Carltons and Senators not have a drain plug?

It's the same box isn't it?  Swappsy the sump?

[Shackeng]

Mine has two sumps.

Mine has two sumps.

Yeah, they all do but only the main sump on the Carlton/Senator boxes had a drain plug.

You don't really have to empty the smaller sump but if the old fluid is bad then you're better to.

[Shackeng]

Just done mine - both- but thought at the time that drain plugs would be handy. Trouble is, they would, if fitted in the base, be open to impact damage, and the sump base is fairly thin.

Looking at pictures of the Carlton/Senator auto sump, it's an alloy one and the drain plug is recessed so that it won't catch anything.  You could probably put one on the side of the sump as close to the bottom edge as possible.  Maybe at the rear would be best then you can lift the car at the front only to drain as much as poss, then lift the back up to bring it level for filling.

Oh, and the Carlton/Senator sump has a hole in the side for the oil cooler return pipe so I'd doubt that a straight swap would be an option.

Could be blanked maybe, and I like the recessed plug.

Changed the oil last night and the warnings I've read about getting covered with oil were correct... Now there's ATF all over the place

I could not find the correct torque values here so I checked TIS and it said:
- oil pan screws 12 Nm
- level plug (hex bolt head) 30-40 Nm

I forgot to torque up the filter, I just put it carefully tight by hand.

One thing I-m not sure about is the quantity of oil. I think I got out around 5-6 litres (yes, I spilled some...) and was able to use 5,8 litres of new oil (and again, yes, some was spilled... on the ground, on me, on all the tools...). How much people have usually been able to fill?

The old oil was quite dark in colour. Also I found greyish sludge in both sumps, esp. in the front one. and the magnet was really dirty with the same grey sludge. No metal chips, no thrust washer.

The job is not difficult in any measure but it is extremely fiddly and awkward, I'd say the most uncomfortable job I know on Omegas. Oil will get literally everywhere.

Sounds about right to me. The sludge and metal filings are a result of wear in the box and are normal. Sounds like it was ready for a change.

Think I got about 5½ litres in when I did mine.

The worst bit of getting covered in the old ATF is that it stinks like crazy and it's more a difficult smell to get rid of than petrol on your hands.

[kcl]

I got only covered by the new atf, the old one went nicely to waste oil buckets and can. But filling was a nightmare, I had a syringe (which naturally leaked from both ends  ) and had to crawl under the car quite a few times.

Once again, tools needed:
- 10 mm socket with short extension, 1/4" or 3/8", 1/2" is too big
- 13 mm wrench for plug (no room for a socket due to lambda wire)
- 13 mm socket (here you can use also the 1/2" set) for filter
- plastic mallet (to release the larger sump from gasket). the smaller one fell off after screws were opened.
- small torque wrench
- do not forget to replace the plug copper washer!

[Kevin Wood]

The best device for filling autoboxes is a cheap "killaspray" type garden sprayer with the spray lance removed and a length of copper microbore pipe inserted, and shaped into a hook at the end. You can just have a cup of tea while you sit and watch it fill.

Yes, I planned to use a killaspray but forgot to purchase one and did not want to use the uber-reliable Gloria one I have... Now, if I had the choice, I would definately use the expensive Gloria spray... well, it's done now... And now I have only one issue left: the smoking.... heads off I guess, but that's another story...

Sounds a bit drastic, could you not try Nicorette first?
