2004 TJ i6. I was checking my power steering fluid level today and noticed it was a little low. I wiped the fluid off the dipstick with a rag and it was a light tan color. I was expecting to see red color for ATF 4 it needs to use. Would it cause any problems if the previous owner added power steering fluid instead of atf4? To top of the fluid level what should I use? Is it worth flushing? Thank you.
