I have done a lot of searching and do not really see anything that applies to this problem. 2006 Escalade that now has a 4L80E and tune has been adjusted to reflect. Everything works flawless until the transmission temp gauge (factory) reads roughly 160*. I get a Transmission Hot across the display and trans will act as if it is in limp mode. I have gone threw the tune settings and can not see if I am missing something or what. I repined the stock transmission plug to correspond the the 4L80E pinouts. Thought or help please.
