That is such a stupid design. Put the cat right next to it so that it cooks the fluid, then take and bury the fill plug so that you can't easily change the fluid. As bad as putting the battery inside the driver wheel well and having to remove the intake to change the spark plugs!
The suggested maintenance list to replace the PTU fluid is ambiguous as to whether it applies to all engines. But after looking up some repair manuals and diagrams the 2.4L engine front wheel drive does not have a PTU that needs fluid changed. This should only be applicable to the models equipped with an AWD engine.
