Hatzie I enjoy your interjections and in my time studying the GM 7427 PCM for my 4L80 after reading this I know about 1/10th of what your saying and that's good because now you are driving my to learn more and that is the #1 reason I come to this site is to find the drive and necessity to know more because if I never knew something existed then I would never know to know more if that all makes sense
