Apparently it is a sealed unit for what that is worth and it is filled with oil that should last the life of the car.
What’s the life of a car at this stage?:rolleyes:
The Volvos use the same box and what I could find is that you have to measure the gearbox temp to establish when it is on the correct oil level.:confused:

It can be changed.
There is a thread somewhere in this section where the dealer (in Greece I think) used the wrong fluid and refused for some time to admit it was wrong.
Eventually they replaced with the correct Tutela GI/VI.

Correct! I read that thread but I am really looking for a guide/manual how to change oil ...

I too would be interested in whether this is a diy thing. I believe that it's a Toyota/Lexus gearbox used by Peugeot and Citroen as well as Alfa ?

Its not a Toyota box but it was developed in Japan as a compact 6spd Auto box that can handle 440nm.
It is used by a lot of manufacturers including Toyota.
The VW’s use the smaller sister of the box.

It is a maintenance free unit but like all things mechanical you can drain it and refill with new oil just make sure that you use the correct oil.

I have also found this post :thumbs:, it is probably the best guide I have found so far.
I don't really understand if there is a procedure but when I did it they just drained the fluid (about 1 liter only) and they put 3.3 liters.
Because of all the wrong fluids they put in, this week I am going to do another change and then another hopefully to get as much of Matryx out.
Why do you want to change it?
Do you have any problems?

If you only got 1 liter out you only unscrewed the smaller plug. To get the rest out you need to unscrew the bigger plug as well. See here: Photo albums - Alfa Romeo 159 Owners Club

If you have drained 1 liter, and then put in 3.3 liters you now have too much oil in the gear box. No good!

Also have a look in this thread where I have answered your incorrect statement about posabilities to check the oil level. http://www.alfaowner.com/Forum/alfa-159-brera-and-946-spider/326701-qtronic-transmission-oil-change.html

My 159 Q4 Qutronic Auto box is playing up a little. Holds gears coming down hill and occasionally not the smoothest of changes.
I am researching how to change the fluid, which does not seem simple.
But while I look at this I notice it is the same box as in many Volvols, including the XC90. But I see from many Volvo forums this box has a level checking dip stick. Why does my Alfa not? Can one from a volvo somehow be installed. Wouldn't this make changing and topping up the fluid a lot simpler?

Like most modern automatics, it needs the fluid replaced whilst on the diagnostic machine as it needs to be at the right temperature and get all the valves flushed in order.

Volvo's with the same box use the same procedure, it's older versions you are looking at if it's ye olde dip stick type.

Its not a procedure for the faint of heart!! I had mine done by autolusso at 80K and it was much smoother afterwards. I will get it done again when I hit 120K.

Open top plug, drench both bottom ones.
Top up about 7 liters (Snitched from Ford Etis, why would Ford use more oil in same gearbox?)
Warm up gearbox, it have to be between 53 and 57C
Go through all gears, remove the smaller plug.

Top up if needed, else let it stop drip from the smaller plug, refit.

Incorrect oilchange may cause hard shifting, slipping on gears and other fun things.
If you don't have the correct tools and diagnostic (And skills), leave it for a workshop.

Just got my 159 back from the shop.
I asked them to change the auto fluid, but as everyone says they just took the "it's a sealed unit" approach.
They told me they did a software update, and it does seem better.
I would still like to do a fluid change.
Instead of the Tutela Multiaxile (that I think should go in the transmission), can I use this this in the box?

Have a search on Google AU for a local Transmission specialists and tell them you have a TF-80SC you want the oil changed in. Seriously, I cant stress this enough, a DIY oil change is likely to end badly in the QTRONIC boxes as they are extremely sensitive to the change procedure and oil type/quantity.

Thanks JabawokJayUk,
Sounds like I need an expert.
Have I read the manual correctly. I need Tutela Multiaxile in my 4x4 box?
Or is it car matryx in the box and multiaxle in the rear diff only.
