I'm going to ask this question again, as I didn't get enough responses on this issue last time I posted. I see a big issue when it's 25 F out or below. So it won't shift up into 2nd very well or 3rd. When it does get to the 4th Gear you can tell the convertor won't unlock this happens on all the gears, but worse on this gear. Fluids where checked and dealer said they are good, checked for codes and updates on transmission, nothing found. I believe my torque convertor isn't operating correctly, as my Father has felt shutter on it when we where stopped at a light. I have had cluncks happen going into 2nd or dropping down to 2nd to low. But the cold weather is really effecting the shifting. Eventually it will shift when I drove it for about 4 or 5 miles.
