You can change the actuator fluid any where between 10 ~20k kms or earlier if you want. If i were you i would do it every 10k. Mobil 1 DOT 4 is good option.
As for transmission fluid 30k kms is safe bet for our climate. ATF-DW1 is HONDA.
I change every 5k kms along with oil filter. Total 0w-20 with original oil filter.
I cant say about this vehicle but generally its 30 to 60k Miles.
Well the place is your personal choice, especially if you know how such things are done.
