Was driving home the other day and the Check Engine light came on and the A/C started to blow more air, noticed the Trans Progrm light on in the Driver info center. Trans went into default made it home. Comes and goes Sometimes it works ok, then it returns, Any Help would be appreciated Thanks Neal

Well I would like to thank the 149 people looking at my post, I figured it out ! When the problem happened I had my volt meter on the battery and noted an over voltage problem.
17.5v I had replaced the voltage regulator on the alternator about 6 months ago and it decided to fail again. I removed the alternator and replaced the electronic regulator assembly again and it works great. Thanks Neal
