Had an issue in my 2007 V8 with the check engine light coming on after being stuck in traffic for two hours going up the 6-7% grade to the Eisenhower Tunnel here in Colorado yesterday. Trac did not over heat, but the computer obviously was messed up as shifting was rough and out of sequence, etc. I disconnected the battery and shorted the terminals then after 20 minutes or so reconnected. Today, I drove to work (125 miles round trip) and mileage was up from 18.5 average to 20.5 average. I have not seen this mileage since last fall when the truck was almost new. I'm sure the computer reset did it. If my mileage falls off agin, I will reset again.
BTW, no more check engine light and shifting is back to normal.
