90 mile from home in a small town and when I started my GX to go home this morning, there was a high whining sound for a while. And then all the dash lights came on. The truck is sluggish and won’t shift out of first gear. I suspect low transmission fluid but it’s sealed so I don’t know what to do. Anything I can do to get me home? I have my wife our dog or cat and my mother-in-law with me and I’m kind of desperate. I’ve called several shops in town and no one can help.
