Caveat: I am not a professional wrench! I am not an expert on Nissan’s; I work on Subaru’s as a hobby!
You may want to get your brakes checked first, as ABS means (Anti-Locking, Braking, system) this may require a different fluid, and goes in a different area. Or your pads may be worn.
As for the Transmission most of the worldwide brands will work it’s called (ATF), although Nissan recommends theirs. If you are going to use the first option of fluid:
1. You need to drain the transmission first, then refill with all fresh fluid.
2. When was the last transmission service done? You may need a new filter.
3. How many KM’s on the car? How old is the car? Is it leaking fluid?
4. What is the service schedule?
The dealer is not always the best option, they usually over charge you, for work that any good mechanic can do.
