I'm not sure what you're referring to when you say "fluid level sensor", I don't think these units have a fluid level sensor. It does sound like you might need a new transmission. However, I would just try overfilling it by about a 1/2 or full quart, just to see if that makes a difference. What could be the harm, I suppose, it does sound like it might be on its last legs right now...
