It seems to not shift properly. Normally when stopped at a light RPMs about 700. Lately its been above 1000 RPMs. I am getting horrible gas mileage. Any suggestions to figure out how to fix the problem appreciated.

    It has turned off while driving once. I pulled over and waited a minute and it started up. Its hard to start if I go in the store for a couple minutes.I don't believe it was overheated though. I felt the hoses and it felt like there was pressure. How would I know if it was the temp sending unit?
