How old should transmission fluid be at 150, 000 miles?

15 years old, 150,000 miles. If your fluid is bright red, somebody has changed it at least once. I’d change fluid and filter if it was mine.

When to change the transmission fluid and filter?

I always change the transmission fluid and filter before 100,000 miles, and can assure you that what comes out is not as clean as it looks on the dipstick.

Can a 15 year old transmission fluid flush?

But this thread is about a 15 year old car with 150K miles with original transmission fluid. Those are the cases where likelihood of problems from doing a flush are no longer near zero.
