Recently bought this 2008 6.4. deleted with spartan tunes. I noticed a couple times the truck (in one specific spot on my road) would get confused in between 2nd and 3rd gear. When it happens I am always coming up a hill and turning. i let off coming up the hill and as I am coming out of the turn at the top when i ease back into it the truck will free rev for a second and then slam into gear. It happened tonight but this time it was so bad that the truck couldnt find a gear for probably 15 seconds and when it finally did it was stuck in 3rd and threw the wrench light. Again, i just bought the truck so can somebody explain this wrench light to me quickly? Its obviously not the CEL. I shut the truck down, started it back up and it drove perfectly normal the rest of the way home. I scanned for codes with the spartan and nothing is showing up. Any ideas? thanks
