I have a x type 2.2 auto with 90000 on the clock, gearbox working fine as far as I know but does it need an oil change, Apparently a sealed unit but on forums it conflicting advice, I have read about changing it a bit at a time but not sure which way to go. Thanks any advice appreciated. 

Welcome to the Club.

I changed the auto gearbox fluid in my last X Type when it was 5 years old in 2014 at Mackies Auto Transmissions in Glasgow as they are a ZF authorised garage.

And never had any problems with it, a Hot Flushing Machine was used to change the fluid. The auto gearbox in the X Type is a Aisin Warner and it's just a Fluid Change as the Filter can only be changed if the gearbox is dismantled for repair. And I believe that the ZF gearbox has the Filter changed along with a New Sump. 

The consensus these day's is that it's not recommended to use a Hot Flushing Machine as Sediment lying in the bottom off the gearbox could cause problems .

Thanks its my first auto and just trying to keep it in its best condition. 

Does the 02 petrol 2.1 V6 have a sealed auto box also?
