Bill I have wondered if a deep pan would help it as well. Brian at BTS doesn't feel deep pans are beneficial as if you get the tranny hot it takes a lot longer to cool it back down with those pans. So I'm running a stock pan.
As I mentioned above about it shifting it really doesn't matter what gear it's in. If the tranny is not spinning it's not spinning so I don't think it's trying to shift into a default gear. When mine as doing it I don't recall the TFT getting all that hot. I mean it was climbing due to loading the TC but not out of range. And I have my temp sensor in the line to the cooler so that's right when it comes out of the TC and at it's hottest point.
BTW what are you doing on the furms while you are on vaca? I mean I love to see you post but man go take vacation!
