I have a 1999 dodge 2500 diesel auto
4wd. Everytime I first start my truck after sitting overnight, it takes about a mile or so before it will shift out of, I think 1st maybe 2nd, like it needs to warm up before it shifts normal. Plenty of power. Took it to the dealer, found no codes, so they flushed the trans. still notice the problem, not as bad now because of the warm weather but still there. Please help if you know anything that will help.
