Well, just took a 170 mile round trip up north and back again. Pretty much all highway with CC set at 70. Still running and shifting smooth as could be, must be about 320 miles or so since the goofy shifts and SES. Maybe I'm pushing my luck, but I can't afford a rebuild or to be without the car right now. If it breaks down I'll have to see what its options are so far as selling/fixing.
Thanks again for your help, guys. Just figured I'd update while my thread's still at the top.
