May i add a question to this topic?
I have a 2001 Nissan Altima (automatic) and i am hesitating if i should change the transmission fluid myself or not. That car has about 107K Miles and i am not sure if it got a change before (used).
This Nissan has only a bold to let the oil out and no filter (at least the manual does not talk about a filter).
I have talked to the nissan part guy and he told me, regarding the fluid, to just get either dextron 2 or 3 and to fill about 5 quarts in it, since the 10 are not needed. I assume some stays in the transmission.
Now i heard that sometimes the transmission could be ruff to drive after a change and now i am just really confused.
It look really easy to do, but since it is a major part of the car i really want to make sure that i'll do it right.
