The car is a '99 chevy cavalier with the 2.2 4 cyl. Going down the highway running 50-55 mph the temp gauge is reading normal . When you get around 60 mph the temp guage will drop to the cold mark and wander back and forth between cold and middle of gauge and you can feel the torque converter unlock . 3 speed automatic. Sometimes it felt like it was dropping back to
2nd gear. What are some possible things to look at. No check engine light coming on.- posted
