hi everyone

need your advise for changing my kenari atf and atf filter.
i called the perodua sc and the adviser do not know what is atf filter. the car is 94000 km now. they told me it is about RM50 only to change atf only.

is it advisable to do outside or back to perodua sc?
my worry is that changing outside will spoil the gearbox due to bad workmanship.

thanks.
