What is your question?
My husband put atf in the brake fluid reservoir. How do I fix this without spending a ton of money? I've replaced everything but the master cylinder and brake booster.
What makes this problem better or worse?
Nothing
How long has your 2001 Lincoln Navigator had this problem?
Months

Well during the process of replacing “everything but the master cylinder” (booster is irrelevant) you should have emptied all or most of the existing fluid from the system - refill master cylinder WITH BRAKE FLUID and continue bleeding all brakes - repeat as necessary.
