I have a 2006 RRS. Each time I start it, I get a beep and a "transmission fault" warning message. Then, when I put it in park, I get the same message. It drives and shifts normally and I am not getting any other messages. After reading the forum, I purchased and installed a new brake light switch and I also checked all the brake light bulbs. That didn't help - I continue to get the same message. Any ideas what to look for next? Thanks.
