Your mechanic is wrong. The 15W-40 oil is fine. I'd almost guarantee that the chart in your owner's manual will verify this. The 0W-40 is recommended strictly for fuel economy reasons, not for protection or longevity. There have been enough reports of problems with 0W-40 that I will NOT use it in my cars. If it makes you both feel better, you could use 5W-40 (either M-1 or Amsoil) instead.
Tranny fluid - that car has the 722.6 tranny, and I would highly recommend sticking with the OE/dealer trans fluid. I would change it at least every 30kmi, along with the filter, and make sure you drain the converter too (otherwise you only get about 1/3 the fluid out). I usually change before 30k though.
