I have an '01 4 cyl. auto. 209k with a few problems that I'm not sure if they are seperate or a combined problem. It has been shifting a little hard going into 3rd gear. Also when I press the gas at a stop it hesitates and then takes off. If I start out in the manual 1st no problem. Also it hasn't happened lately but tends to get really hot when the temps are high and lots of mountain hills. I haven't taken the chance to see if it will get all the way to overheating but have been close enough. When this happens the a/c blows outside air once the needle is 3/4 of the way to overheating. Any help would be appreciated.
