OK... my Taurus has trouble choosing a gear to be in between 2nd and 3rd. It will cycle between the two over and over for about 3 times and pick the higher gear, bogging it down. This is when applying a steady acceleration. If I REALLY punch it, it won't really do it... it may do it a tiny bit. I think it may be some kind of vaccuum thing, but I am not sure. Also, just in the last couple days, a chirping sound has started (but it doesn't sound like a loose belt or anything). And, I noticed that it is getting hotter while driving. The fluids all seem to be fine, but it is getting increasingly more important to find a solution. Thanks in advance for any and all help you can provide!
