Thanks for the reply.
Actually the SEL light went off yesterday, not sure why. My transmission fluid was replaced 5k miles ago or so - it looked good when it was replaced, but figured after 100k miles it was a good time to change it out. The transmission problems seem to be doing better as well. I really don't understand how any of the problems would go away on their own but I'm not going to complain. I haven't driven it enough to say all my problems are fixed but its definitely doing better.
