How do you remove the transmission on a Jaguar X type 2002 ?

The lower port is located on the larger of the two lines going in/out of your A/C compressor (the lines are silver tubes and your compressor will have a belt of some sort attached to it).  You can also tell which is the lower port because that line will be cool/cold while the high side port line is smaller and will be warm/hot while the A/C is running on max.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door
