Greetings all. I seem to be having a problem that is described in the 2nd Gen section. When starting from 0 I have to run the truck up to about 3000 rpm before it shifts. This started about a month ago and I've been trying to find an answer. I'm wondering if the fix is the same in dropping the transmission pan and replacing a couple of sensors. After it makes that first shift it seems to operate normally. When its warm it doesn't seem as severe. I don't have any check engine lights. The truck has a 5.9L with 150xxx miles. Any ideas would be most appreciated. Thanks
