There are plenty of topics already on this. Do you have the AM6 box? Pop your VIN up if unsure.

If AM6 on a C5 X7:

Don't forget you MUST reset the oil counter after changing the oil, so will need Diagbox or a compatible diagnostic system to do that. It will ideally need to be done over 3 changes as you can never empty the torque converter, so only 3 out of the 7 litres can be changed at any one time.

Ok, so you have the DW40CTED4 engine with AM6 gearbox, so yes, follow the guide in the links I gave you.

As you have a Euro 5 engine and gearbox, you'll need AW1 transmission oil or equivalent NOT JWS3309 which is only to be used for Euro 4 vehicles.
