I have had this same problem for months on my 2001. I changed the transmission about 4k miles ago, and keep an eye on the brake fluid reservoir. Over the weekend, I did an oil change, flushed the power steering fluid, and checked everything else. Brake fluid was completely empty! I filled it, and have checked every 30 miles, or so. I keep expecting a significant drop, assuming that I've got a leak, but after about 100 miles, it's still completely full... Kind of at a loss. Could be a coincidence, I guess, but either way, I've still got a stiff shifting problem. Any further thoughts would be greatly appreciated. Thanks!
