I would just like to run this by some people and see if I am diagnosing this right. OK I have a 1999 GA GT 3.4L with 70,000 miles on it and about 2 months ago I started to notice that the temp gauge was reading higher then it used to and when this happened the tranny would want to slip a little bit on me in Drive (but only when I would change from park to Drive or Reverse to Drive). I now am starting to notice that the engine wants to continue to heat up even after I turn the car off and acceleration seems down a little, all of this is making me think and has been suggested to me that my Cat Converter could be clogged up, not letting exhaust gasses escape as much as they need to.

Any other diagnoses would be appreciated
