Would you re use your auto transmission fluid if it was only in the car for 3 years, is clean and only has about 2 or 3 thousand miles on it?
...and how about the anti freeze also?
Depends.
If I was rich I would use all new fluids, but I have reused both from swapping a radiator or a pan gasket.
I just won't use the last little bit of either fluid when it goes back in, and they have to look really good.
