2000 LX with 321k miles. No tranny fluid changes. No problems.
Btw, I think $12-13k for a low mileage 2000 LX is not the best deal in the world. The low mileage factor is deceptivley deceiving.
I have 265k on my 2000 with zero fluid changes. Bought at 48k miles. So I'm sure it's the original fluid. Fluid doesn't smell burnt or anything. It's deep red color is about the only indication it's old.
