Message: Hello to all! I have a stock 98 Dak w/3.9 6er 135K miles. My transmission won't shift into Over drive sometimes. When it does this, the check enj. light comes on. If i floor it and make it kick down into 2nd, then it will shift into 3rd then into OD. The tranny has not been serviced in 25 or 30K. I replaced the computer not long ago due to lack of fire, so i dont think this is the prob.(it did it with the old PCM) THANKS for any help! Chris
